## Abstract

The difference of factor input structure determines different response to environmental regulation. This paper constructs a theoretical model including environmental regulation, factor input structure, and industrial transformation and conducts a policy simulation based on the difference of influencing mechanism of environmental regulation considering industrial heterogeneity. The findings show that the impact of environmental regulation on industrial transformation presents comparison of distortion effect of resource allocation and technology effect. Environmental regulation will promote industrial transformation when technology effect of environmental regulation is stronger than distortion effect of resource allocation. Particularly, command-control environmental regulation has a significant incentive effect and spillover effect of technological innovation on cleaning industries, but these effects do not exist in pollution-intensive industries. Command-control environmental regulation promotes industrial transformation. The result of simulation showed that environmental regulation of market incentives is similar to that of command-control.

## Body

## 1. Introduction

Environmental regulation is one of the policies and measures by which the government solves “market failure” of environmental issue, which has become an important way to push industrial transformation. The main cause of industrial transformation is technological innovation. According to Porter [1, 2], the appropriate environmental regulation policy helps to stimulate the enterprises to carry out technological innovation, which can be called the effect of technological innovation incentive. Jaffe and Palmer [3] present three distinct variants of the so-called Porter Hypothesis, namely, the “weak” version, the “narrow” version, and the “strong” version. Lanoie et al. [4] tested the significance of these different variants of the Porter Hypothesis using data on the four main elements of the hypothesized causality chain (environmental policy, research and development, environmental performance, and commercial performance). They found strong support for the “weak” version and qualified support for the “narrow” version and the “strong” version. Ambec et al. [5] provided an overview of the key theoretical and empirical insights on the Porter Hypothesis to date. Blind [6] differentiated between economic, social, and institutional regulations following the OECD taxonomy on regulations. The results confirmed the hypotheses derived from the conceptual theoretical framework determining technical progress and innovation endogenously and allowing a distinction between short-term and long-term effects. So the influence of environmental regulation on technological innovation is determined by many factors.In terms of industrial sector, the adjustment of industrial production capacity is related to the proportion of fixed capital in production factors input. The fixed cost is higher relatively in pollution-intensive industries, due to the large fixed capital input, the complexity of technology, and the specificity of equipment. It is difficult to update technology for pollution-intensive industries when environmental regulation intensity increases. Pollution-intensive industries may augment production factors input to offset environmental regulation cost, which will cause a distortion effect of resource allocation. In contrast, it is easier to change technology for cleaning industries when environmental regulation intensity increases. Cleaning industries will increase R&D investment to improve technology to avoid environmental regulation cost, which will cause incentive effects and spillover effects of technological innovation. Therefore, the increase of environmental regulation intensity ultimately drives the adjustment of industrial structure [7].Many literatures focused on the effect of environmental regulation on industrial structure transformation from proportion of the third industry and secondary industry perspective [8, 9]. Li [8] addressed environmental regulations which will improve the proportion of the service sector relative to the industrial sector and promote the adjustment of industrial structure. The previous literatures were more concerned with the incentive effect of environmental regulation on technological innovation within the industrial sector. For instance, Bai and Song [10] found that environmental regulation can improve the efficiency of Chinese thermal power as a whole and cause incentive effects of technological innovation. Zhang et al. [11] conducted an empirical test on industrial sectors of 30 provinces in China and found that the effect of environmental regulation on technological progress rate is different among different regions. In recent years, many researchers found that industrial heterogeneity plays a very important role in the relationship between environmental regulation and technological innovation, but the conclusion is not consistent [12–15]. Li and Tao [12] indicated environmental regulation intensity of heavy pollution industry can promote the industrial green total factor productivity, the environmental regulation intensity of the moderate pollution industry is weak, and technological innovation can be early breakthrough “U” inflection point for light pollution industry. Nie and Huang [15] found the current strength of environmental regulation hinders the improvement of moderate energy-intensive industries in total factor energy productivity, technological innovation, and efficiency improvements; highly energy-intensive industries’ environmental regulatory intensity does not significantly influence the total factor energy productivity; for the mild energy-intensive industries, the intensity of environmental regulation promotes technological innovation.The existing literatures mostly focused on the effect of environmental regulation on industrial structure at the country or region level and paid little attention to the impact of environmental regulation on industrial transformation inside the industrial sector. In the meantime, the structure of factors input may cause different response to environmental regulation in pollution-intensive industries and cleaning industries. Therefore, we construct a theoretical model to analyze different effect of environmental regulation on heterogeneity industries in this paper. Then we conduct a simulation to examine the effect of different environmental regulation policy and put forward some suggestion.


## 2. The Mathematical Model

Environmental regulation includes command-control and market incentive regulation. In this paper, we select environmental regulation intensity as a proxy of command-control environmental regulation, environment tax, and environmental technology subsidies as a proxy of market incentive environmental regulation. Further we assume that technology is relatively fixed for pollution-intensive industries, but environmental technology will continue to change for cleaning industries in the process of production. Pollution-intensive industries are likely to increase inputs to offset the cost of regulation when environmental regulation intensity increases, namely, the distortion effect of resource allocation. And cleaning industries will promote the environmental technology, namely, the incentive effect of technological innovation. At the same time, the technology change will make organization structure and management mode change further, eventually leading to improvements in total factor productivity, namely, technology spillover effect. In short, the distortion effect of resources allocation represents the distortion of environmental regulation; moreover incentive effect and spillover effect of technological innovation reflect the externality of environment regulation. When distortion effect of environmental regulation is bigger than the externality (namely, the benefit that pollution-intensive industries accept tax punishment and increase factors input is higher), environmental regulation will inhibit industrial transformation. When the externality of environmental regulation is greater than distortion effect (namely, incentive effect and spillover effect of technology innovation for cleaning industry is higher), environmental regulation will promote industrial transformation. In the following section, the dynamic general equilibrium model is selected to analyze the mechanism.


### 2.1. The Effect of Environmental Regulation on Pollution-Intensive Industries

The capital, labor, and environmental resources are input in the process of production in pollution-intensive industry. Because of consumption of environmental resources, pollution emissions will be produced. Here, environmental resources include fossil energy and other natural resources, for instance, soil and water and air. As mentioned above, pollution-intensive industries are restricted by replacement cost of machinery and equipment, so environmental technology is relatively fixed, which can only accept tax penalties. Therefore, the production function in pollution-intensive industries is as follows:(1)

When environmental regulation intensity is high, enterprises require burdening higher cost of tax. Therefore, there is a trade-off between increasing environmental resources consumption and reducing the environment resources consumption. So the profit function in pollution-intensive industries is as follows:(3)

.Equations (4) and (5) denote the price of capital and labor equal to their marginal output, respectively. Equation (6) denotes the marginal output of environmental resources is equal to the sum of environmental resources price and tax cost which is caused by increasing environmental resources consumption to produce environmental pollution increment.


### 2.2. The Effect of Environmental Regulation on Cleaning Industries

Cleaning industries generally include large enterprises with the stronger comprehensive technology research and development ability and small businesses with emerging technology. The higher the intensity of environmental regulation, the stronger the motivation of green technology strategy carried out by cleaning industries. According to Porter [1, 2], the appropriate environmental regulation policy helps to stimulate the enterprises to carry out technological innovation, which can be called the effect of technological innovation incentive. The cleaning industries will increase green R&D investment, improve the level of human capital, and develop perfect system environment, which in turn improve technological management level and change organization structure and management mode, eventually leading to improvements in total factor productivity, namely, technology spillover effect. Cleaning industries also will discharge pollution in the process of production. In order to expand technology innovation incentive effect, the government will impose subsidy to R&D investment of environmental technology in cleaning industries. Therefore, the production function in cleaning industries is as follows: (7)

.Equations (10) and (11) denote the price of capital and labor equals their marginal output. Equation (12) denotes that the marginal output of environmental resources is equal to the sum of environmental resources price and tax cost which is caused by increasing environmental resources consumption to produce environmental pollution increment. Equation (13) denotes that the price of R&D capital of environmental technology is equal to the sum of marginal output increment and the reduction of tax cost caused by environmental technology innovation and the governmental subsidy for R&D investment of environmental technology.

2, because there is a complex nonlinear relationship among them. Equations (26) are steady state equations of the equilibrium solution. Industrial structure is the optimal structure under the steady state of model, because it achieves profits maximization and lifetime utility maximization of representative families simultaneously, which is to maximize the social welfare. The optimal industrial structure is determined by the parameters of the model at the same time based on the steady state equations (26); namely, the optimal industrial structure is a function of environmental regulation policy. Industrial structure transition is decided by the government’s environmental regulation policy. Pollution-intensive industries will gradually reduce the scale of production to drop cost, and cleaning industries will improve the environmental technology which is affected by technology innovation incentive effect when the government makes a tougher environmental regulation policy. Technology spillover effect leads to the improvement of total factor productivity which will promote the cleaning production scale to achieve the aim of industrial transformation. There are more than a dozen exogenous parameters in steady state equations, which have complex nonlinear relationship. Therefore, we analyze the existence of the technological innovation incentive effect and the technology spillover effect and the mechanism of environmental regulation on industrial transformation by simulation computation method with MATLAB software:(26)

### 2.6. Calibration of Parameters

(

The division standard of industrial sectors is in accordance with “China Industry Economy Statistical Yearbook.” To be sure, because the data is missing partly in Manufacture of Artwork and Other Manufacture, recycling and processing of waste resource and old materials, and Mining of Other Ores, we remove these subindustries. In addition, we incorporate manufacture of plastic and manufacture of rubber to maintain consistent statistical standard, due to industrial classification standard changed in different years. After the adjustment, we get 35 subindustries. Further, all the industries are divided into cleaning industries and pollution-intensive industries based on the median of the pollution emission intensity. The calculation of the pollution emission intensity (EMI) is as follows.①

2) Environmental Regulation Intensity. Environmental regulation is measured from 6 dimensions in the previous literature [11]. First is the type of environmental regulation policy. Second is the proportion of investment of pollution treatment in total cost or output value. Third is running cost of pollution control facilities. Fourth is the per capita income. Fifth is the number of governments’ inspection. Sixth is the volume of pollution emissions. Considering the availability of industry data, we select running cost of pollution control facilities as the measurement of environmental regulation intensity. According to Shen [13], we choose the proportion of running cost of pollution control that accounts for industrial output as a proxy. The total running cost of pollution control is the sum of running cost of wastewater and waste gas control in each sector. The data source of environmental variables is “China Environment Statistical Yearbook” and the data source of industrial output is “China Industrial Economic Statistical Yearbook.”(
3) The Estimation of Production Function in Pollution-Intensity Industries and Cleaning Industries. We estimate the production functions of cleaning industries, pollution-intensity industries, and energy industries (here, we use mining and washing of coal to substitute energy industries) based on panel data in 30 provinces (excluding Tibet) from 2002 to 2012. And we decompose total factor productivity to get technological progress rate and do regression analysis between technological progress rate and R&D investment in cleaning industries.The regression results are shown in Table2.Table 2
The estimated results of the production function and technological progress rate.

4) The Estimation of the Function of Pollution Emissions. Since the data of waste water and solid waste are missing partly, we select the volume of SO2 emissions as a proxy in pollution-intensity industries and cleaning industries.

## 2.1. The Effect of Environmental Regulation on Pollution-Intensive Industries

The capital, labor, and environmental resources are input in the process of production in pollution-intensive industry. Because of consumption of environmental resources, pollution emissions will be produced. Here, environmental resources include fossil energy and other natural resources, for instance, soil and water and air. As mentioned above, pollution-intensive industries are restricted by replacement cost of machinery and equipment, so environmental technology is relatively fixed, which can only accept tax penalties. Therefore, the production function in pollution-intensive industries is as follows:(1)

When environmental regulation intensity is high, enterprises require burdening higher cost of tax. Therefore, there is a trade-off between increasing environmental resources consumption and reducing the environment resources consumption. So the profit function in pollution-intensive industries is as follows:(3)

.Equations (4) and (5) denote the price of capital and labor equal to their marginal output, respectively. Equation (6) denotes the marginal output of environmental resources is equal to the sum of environmental resources price and tax cost which is caused by increasing environmental resources consumption to produce environmental pollution increment.


## 2.2. The Effect of Environmental Regulation on Cleaning Industries

Cleaning industries generally include large enterprises with the stronger comprehensive technology research and development ability and small businesses with emerging technology. The higher the intensity of environmental regulation, the stronger the motivation of green technology strategy carried out by cleaning industries. According to Porter [1, 2], the appropriate environmental regulation policy helps to stimulate the enterprises to carry out technological innovation, which can be called the effect of technological innovation incentive. The cleaning industries will increase green R&D investment, improve the level of human capital, and develop perfect system environment, which in turn improve technological management level and change organization structure and management mode, eventually leading to improvements in total factor productivity, namely, technology spillover effect. Cleaning industries also will discharge pollution in the process of production. In order to expand technology innovation incentive effect, the government will impose subsidy to R&D investment of environmental technology in cleaning industries. Therefore, the production function in cleaning industries is as follows: (7)

Equation (13) denotes that the price of R&D capital of environmental technology is equal to the sum of marginal output increment and the reduction of tax cost caused by environmental technology innovation and the governmental subsidy for R&D investment of environmental technology.

## 2.5. Model Solutions

2, because there is a complex nonlinear relationship among them. Equations (26) are steady state equations of the equilibrium solution. Industrial structure is the optimal structure under the steady state of model, because it achieves profits maximization and lifetime utility maximization of representative families simultaneously, which is to maximize the social welfare. The optimal industrial structure is determined by the parameters of the model at the same time based on the steady state equations (26); namely, the optimal industrial structure is a function of environmental regulation policy. Industrial structure transition is decided by the government’s environmental regulation policy. Pollution-intensive industries will gradually reduce the scale of production to drop cost, and cleaning industries will improve the environmental technology which is affected by technology innovation incentive effect when the government makes a tougher environmental regulation policy. Technology spillover effect leads to the improvement of total factor productivity which will promote the cleaning production scale to achieve the aim of industrial transformation. There are more than a dozen exogenous parameters in steady state equations, which have complex nonlinear relationship. Therefore, we analyze the existence of the technological innovation incentive effect and the technology spillover effect and the mechanism of environmental regulation on industrial transformation by simulation computation method with MATLAB software:(26)

## 2.6. Calibration of Parameters

(
1) The Division of Cleaning Industries and Pollution-Intensive Industries. The division standard of industrial sectors is in accordance with “China Industry Economy Statistical Yearbook.” To be sure, because the data is missing partly in Manufacture of Artwork and Other Manufacture, recycling and processing of waste resource and old materials, and Mining of Other Ores, we remove these subindustries. In addition, we incorporate manufacture of plastic and manufacture of rubber to maintain consistent statistical standard, due to industrial classification standard changed in different years. After the adjustment, we get 35 subindustries. Further, all the industries are divided into cleaning industries and pollution-intensive industries based on the median of the pollution emission intensity. The calculation of the pollution emission intensity (EMI) is as follows.①

2) Environmental Regulation Intensity. Environmental regulation is measured from 6 dimensions in the previous literature [11]. First is the type of environmental regulation policy. Second is the proportion of investment of pollution treatment in total cost or output value. Third is running cost of pollution control facilities. Fourth is the per capita income. Fifth is the number of governments’ inspection. Sixth is the volume of pollution emissions. Considering the availability of industry data, we select running cost of pollution control facilities as the measurement of environmental regulation intensity. According to Shen [13], we choose the proportion of running cost of pollution control that accounts for industrial output as a proxy. The total running cost of pollution control is the sum of running cost of wastewater and waste gas control in each sector. The data source of environmental variables is “China Environment Statistical Yearbook” and the data source of industrial output is “China Industrial Economic Statistical Yearbook.”(
3) The Estimation of Production Function in Pollution-Intensity Industries and Cleaning Industries. We estimate the production functions of cleaning industries, pollution-intensity industries, and energy industries (here, we use mining and washing of coal to substitute energy industries) based on panel data in 30 provinces (excluding Tibet) from 2002 to 2012. And we decompose total factor productivity to get technological progress rate and do regression analysis between technological progress rate and R&D investment in cleaning industries.The regression results are shown in Table2.Table 2

4) The Estimation of the Function of Pollution Emissions. Since the data of waste water and solid waste are missing partly, we select the volume of SO2 emissions as a proxy in pollution-intensity industries and cleaning industries. We construct the regression equation in which energy consumption is independent variable and the volume of pollution emissions is dependent variable.The results are shown in Table3.Table 3

### 3.1. The Impact of Command-Control Environmental Regulation on the Industrial Transformation

(
1) Incentive Effects of Technological Innovation. Figure 1 is a comparison of the existence situation related to technological innovation incentive effects of the environmental regulation intensity in different types of the industry. As shown in Figure 1, the enhancement of the environmental regulation intensity does not affect the level of environmental technology as for pollution-intensive industries but promotes the cleaning industries to enhance their level of the environmental technology. It means that technological innovation incentive effects of the environmental regulation intensity do not exist in terms of pollution-intensive industries, while they exist in the cleansing industries. The cause of this phenomenon is the difference of the cost input model between these two types of industry.Figure 1
The existence analysis of technological innovation incentive effects of command-control environmental regulation.(
2) Technology Spillover Effect. Figure 2 is a comparison of the existence situation related to technology spillover effects of the environmental regulation intensity in different types of the industry. As shown in Figure 2, the enhancement of the environmental regulation intensity does not affect the total factor productivity as for pollution-intensive industries but leads to the increase of the total factor productivity in cleaning industries. It means that technology spillover effects of the environmental regulation intensity do not exist in the pollution-intensive industries, while they exist in the cleansing industries.Figure 2
The existence analysis of technology spillover effects of command-control environmental regulation.(
3) The Impact of Command-Control Environmental Regulation on the Industrial Transformation. Figure 3 is the impact of the command-control environmental regulation on the industrial transformation. As shown in Figure 3, when the environmental regulation intensity is enhanced, those enterprises will afford heavier tax if they increase pollution emissions. Since the environmental technology of contaminative enterprises is relatively fixed without any other responses except reducing the yield, the pollution-intensive industries still carry out the original mode of production but the equilibrium will be moved down along the original production function. However, the cleansing industries have the subjective initiative in the process of tax cost raise. Reduction of yield cannot bring the marketing competitive edge for cleansing industries under the condition of environmental tax. Thus, the cleansing industries need to increase the research input of environmental technology to decrease the tax burden of environmental tax. Meanwhile, when the environmental regulation intensity is enhanced, the cleansing industries will accelerate the R&D and innovation of technology, enhance the productivity, increase the output, and upgrade the industrial structural transformation for obtaining the competitive edge.Figure 3

### 3.2. The Impact of Market Incentives Environmental Regulation on the Industrial Transformation

(
1) Incentive Effects of Technological Innovation. Figure 4 is a comparison of the existence situation related to technological innovation incentive effects of the market incentives environmental regulation in different types of the industry. As shown in Figure 4, the enhancement of the environmental tax and subsidies of environmental technology R&D do not affect the level of environmental technology as for pollution-intensive industries but promote the cleaning industries to enhance their level of the environmental technology. It means that technological innovation incentive effects of the market incentives environmental regulation do not exist in terms of pollution-intensive industries, while they exist in the cleansing industries. In addition, technological innovation incentive effects of subsidies of environmental technology R&D should be higher than that of the environmental tax.Figure 4
The existence analysis of technological innovation incentive effects of market incentives environmental regulation.(
2) Technology Spillover Effect. Figure 5 is a comparison of the existence situation related to technology spillover effects of market incentives environmental regulation in different types of the industry. As shown in Figure 5, the enhancement of the environmental tax and subsidies of environmental technology R&D do not affect the total factor productivity as for pollution-intensive industries but lead to the increase of the total factor productivity in cleaning industries. It means that technology spillover effects of the market incentives environmental regulation do not exist in terms of pollution-intensive industries, while they exist in the cleansing industries. In addition, technology spillover effects of subsidies of environmental technology R&D should be higher than that of the environmental tax.Figure 5
The existence analysis of technology spillover effects of market incentives environmental regulation.(
3) The Impact of Market Incentives Environmental Regulation on the Industrial Transformation. Figure 6 is the impact of the market incentives environmental regulation on the industrial transformation. As shown in Figure 6, the rise of environmental tax will increase the environmental cost of enterprises. Since the environmental technology of contaminative enterprises is relatively fixed without any other responses except reducing the yield, the pollution-intensive industries still carry out the original mode of production but the equilibrium will be moved down along the original production function. However, the cleaning industries have subjective initiative to deal with environmental tax. Reduction of yield cannot bring the marketing competitive edge for cleaning industries under the condition of environmental tax. Thus, the cleansing industries need to increase the research input of environmental technology to decrease the tax burden of environmental tax. Nevertheless, the motivation of environmental technology innovation is dependent on the relationship between the cost of environmental tax and the cost of environmental technology innovation. In the long run, the cost of environmental tax cleansing industries that the cleansing industries required to pay is inevitably higher than the cost of environmental technology innovation. The technology innovation of cleansing industries will bring the quality improvement of cleaning products and upgrading of the industry. Overall, the real GDP is decreased; the cleansing industries have been developing gradually whereas the pollution-intensive industries have been shrinking. The transformation of industrial structure has been accelerated.Figure 6
The impact of market incentives environmental regulation on the industrial transformation.The subsidies of environmental technology R&D rise and the cost of environmental technology R&D for cleansing industries reduced so that cleansing industries aspire to increase the input of environmental technology R&D to promote its improvement. The environmental technology spillover effects of cleansing industries can improve the enterprises’ productivity and extend the yield scale since the human resources are trained and the level of management is developed. The increase of capital accumulation portion of all the output in terms of cleansing industries causes the increase of the real GDP. Correspondingly, the part of capital accumulation for pollution-intensive industries will be increased too due to the wealth effect that leads to the output increase. However, the growth of cleansing products output brought by the improvement of environmental technology of cleansing industries exceeds that of pollution-intensive industries, so the industrial structure transformation is upgraded.Generally speaking, both incentive effects of technological innovation and technology spillover effect exist in the cleansing industries, while both of them do not exist in the pollution-intensive industries. Meanwhile, the environmental regulation policies assist in improving the transformation of industrial structure. There are two influent channels. First, the enhancement of environmental regulation intensity results in the cost increase of pollution emission as for pollution-intensive industries. In the short term, pollution-intensive industries may increase factor input to make up for the loss of pollution emission, but, in the long term, these industries can only maximize the operating profit by reducing the production scale. Second, under the enhancement of environmental regulation intensity, the cleansing industries will improve its level of environmental technology. Technology spillover effects will extend the production scale for the cleansing industries which promote the transformation of industrial structure.

## 4. Conclusion

In this paper, the entire industries are divided into two parts, cleaning industries and pollution-intensive industries. We constructed a mathematical model and conducted numerical simulation; the results indicated that the impact that environmental regulation has on industrial transformation presents comparison of distortion effect of resource allocation and technology effect. Environmental regulation will promote industrial transformation when technology effect of environmental regulation is stronger than the distortion effect of resources allocation. Particularly, command-control environmental regulation has a significant incentive effect and spillover effect of technological innovation on cleaning industries, but these effects do not exist in pollution-intensive industries. Command-control environmental regulation promotes industrial transformation. The results of simulation to market incentives environmental regulation are similar to command-control environmental regulation.According to the conclusion, we suggest that the government should improve the mechanism of investment and financing gradually, widen the ways of financing, accelerate the process of financial reform, and attract private capital into cleaning industries to support the development of cleaning industries to produce technology spillover effect. The government should set up the appropriate environment access standards to guide the environment control and realize the pollution source management for pollution-intensive industry. The government should combine market incentives environmental regulation and command-control environmental regulation effectively to guide cleaning industries to environment governance and improve the effectiveness of environmental regulation.
