Authors: Zeng Fanyi
Published: October 2022

Financial innovation's impact on the socio-economic resilience cannot be disregarded in the context of the ongoing pursuit of innovation. This study employs a variety of econometric models, including the moderating effect and the mediating effect, to experimentally assess the relationship between financial innovation and economic resilience. The study's findings show that: financial innovation can significantly boost a province's economic resilience; the proportion of state-owned enterprises mitigates the benefits of financial innovation for economic resilience; and improving industrial structure and market activity are two ways that financial innovation boosts economic resilience. Thus, the research in this paper promotes the understanding of the development effect of financial innovation and provides a reference for the path of economic resilience enhancement.

An improved ARIMA model based on regularized Gaussian basis function and its application to stock price forecasting
Authors: Xu Xinyu , Du Yuqing , Lie Jie
Published: October 2022

We propose an improved ARIMA model based on regularized Gaussian basis expansion, which is a generalized linear model. This approach takes into account the auxiliary information of intra-day prices, does not require the assumption of linear smoothing and is able to capture the functional features in high-dimensional time series. Specifically, the discrete series of intra-day prices are first functionalized by Gaussian basis smoothing and fitted to the residuals obtained from the ARIMA model using the basis function coefficients, and the fitted model is chosen as a random forest. The empirical results show that the RT-ARIMA model considering auxiliary information is more accurate than the original ARIMA model. And we performed a robustness test by adjusting the size of the training set, and the results show that the method is robust. This model is helpful to improve the accuracy of stock price prediction and other complicated stochastic systems.

Authors: Chen Jiexin , Cheng Yilan , Li Yu
Published: October 2022

Political struggle is an important factor affecting the pattern of the international oil trade. The escalation of collisions between Russia and Ukraine, and the economic sanctions that the United States and European countries implemented against Russia had a significant impact on Russian oil exports. In this context, it is crucial to study how Chinese and American stock markets react to the burnt of international crude oil prices, in order to understand the phenomenon of risk contagion between markets and prevent risks. This paper selects the settlement prices of the Dow Jones index, S&P 500 index, Nasdaq index, Shanghai index, Shenzhen index, and international crude oil futures prices from three months before the Russian-Ukraine Conflict to the end of May 2022 to illustrate the tolerance to the volatility of two markets, using VAR and ARMA-GARCH model. The empirical results indicated that crude oil price fluctuation has a stronger impact on the US stock market than on the Chinese stock market, and specific stocks act differently during this “black swan incident”.

Analysis of the hedging strategy for the huge loss of Sinopec Group
Authors: Zhang Jiahao
Published: October 2022

The use of crude oil futures for hedging is common for companies that use crude oil as a raw material. It helps companies to hedge against the risks associated with the volatility of crude oil prices and avoid major problems such as cash flow shortages. However, if hedging is abused, it can also have a significant impact on a company's profits. In late 2018, one of Sinopec Group's subsidiaries, United Petrochemical, mistakenly used financial derivatives to hedge, resulting in a plunge in net profit and share price for the entire group. This article analyses Sinopec Group's financial position for the three years 2017, 2018, and 2019, examines United Petrochemical's hedging strategy, and ultimately points out the reasons for and implications of its failure, with a view to providing lessons for the subsequent use of financial derivatives for hedging in related industries. The authors found that a subsidiary of Sinopec Group incurred large losses when international crude oil prices fell as it bought too many futures, causing Sinopec Group's profits to fall by more than 90% in the fourth quarter of 2018 and evaporating more than RMB 90 billion in market value in the two days the deal came to light.
The Usage Depth of Digital Finance and SMEs’ Inefficient Investment: Evidence from the A-share Market
Authors: Zhang Yinan
Published: October 2022

In recent years, digital inclusive finance has developed rapidly in China. The academic community generally believes that digital finance, as a supplement to traditional financial institutions, has eased the financing constraints of enterprises. But from another point of view, digital finance may cause enterprises to be over-financialized and thus lose efficiency. This paper tries to verify this channel. Through OLS estimation and panel fixed effect regression, this paper finds that an increase of 1% in usage depth of digital inclusive finance will lead to a rise of 0.0029 in the inefficient investment level of middle-sized and small enterprises (SMEs). Heterogeneity analysis shows that digital inclusive finance has a greater impact on the inefficient investment level of large enterprises. This study helps to clarify the negative effects of digital finance.

Approaches of Tackling MNEs Tax Avoidance From Legal Perspective
Authors: Yang Jiacheng
Published: October 2022

MNEs’ tax avoidance has caused a serious loss of governments’ fiscal revenue. Governments and international organizations have taken several approaches to tackle this problem. However, there is no one-size-fits-all solution to this problem at present. What's more, the effectiveness of current measures needs to be examined, and more effective approaches to tackle and end tax avoidance should be proposed, so first, this article summarizes the approaches which were exploited widely by governments recently and collects relative data. And then, employing a database carries out a comparative analysis of the merits and demerits of each approach. What’s more, this research shows more possible effective new methods to tackle MNES’ tax avoidance. Based on the results of the comparative analysis, although it seems that the most effective method for governments to end MNE’s tax avoidance is reducing the corporate income tax rate in their jurisdiction, this approach may reduce their overall corporate tax revenue, which causes most government reluctant to do so. Apart from that, implementing restrictive regulations on the income identification of parent companies is also helpful to prevent subsidiaries from avoiding high taxes by leaving their income overseas. What’s more, setting a uniform global corporate income tax rate or a global minimum corporate tax rate seems the most reasonable method. This method could cut the motivation of MNEs to avoid tax to some extent. The article lists several approaches employed by different countries and explores the function of each method to figure out their effectiveness. Furthermore, some possible new methods are proposed in this article.
Theoretical Analysis of Net Present Value
Authors: Chen Xinyi
Published: October 2022

This paper reviews researches on net present value done by researchers in the past 25 years to summarize the research results and put forward limitations. Although the investment decision guided by net present value possesses a long history and investors use it widely in the current financial market, the author believes that it still has the value of being discussed and studied. After a comprehensive review, it is found that in the past 25 years, the research on net present value has focused on comparing its advantages and disadvantages with other investment decision-making schemes and how to apply the NPV approach to special industries, but less follow-up on the actual progress of subsequent investment projects. Despite the NPV approach is generally accepted as the gold standard for enterprises to make investment decisions, with the continuous development of international finance and economy, the success rate of using the NPV approach for investment might be extraordinarily different from that when the NPV approach was initially popularized. After the review, this paper finds that researchers lack practical consideration for the NPV approach. Therefore, the significance of this review is to attract researchers' attention to the above issue so as to make up for the gap in the later stage of research on the implementation of the NPV approach.

Authors: Xu Yanbing
Published: October 2022

With the rapid development of high-frequency trading, intraday trading has become more and more popular due to its important role in understanding the efficiency of the intraday market and capturing more trading opportunities. This article explores whether there is momentum effect and reversal effect in China’s stock market by studying the correlation and predictability between half-hour returns. The results show that there is an intraday momentum effect between the first half-hour and full-day returns. After the investment strategy, it is found that this effect has economic significance, but after considering the transaction costs, the momentum effect cannot make investors obtain excess returns. These costs are the reason for the long-term predictability of intraday returns.

Authors: Zhou Ziyan
Published: October 2022

The IPO phenomenon is a hot issue based on the financial field of listed companies. China has the phenomenon of IPO underpricing, and the underpricing of new shares in China is much higher than that in other countries. Unlike western countries, China's financial repression phenomenon is stronger, the financial environment is special, and there are more retail investors in China's stock market, which are more obviously influenced by emotions and have a strong herd mentality. IPO underpricing has more negative impact on China's capital market. This paper analyzes the reasons for investors' emotional frenzy on the first day closing price of GEM new shares listed from the perspective of behavioral finance. From the perspective of investor sentiment, this paper selects the proxy variables of investor sentiment in different levels of markets and uses multiple regression method to study the impact of investor sentiment on IPO underpricing. It is found that the winning rate is adversely connected with IPO underpricing, while turnover rate is positively correlated with it, and corresponding policy suggestions are put forward. The results in this paper benefit certain investors in the financial market.

Spatial Spillover Effects of Co-Agglomeration of Producer Services on the Upgrading of Global Value Chain: Evidence from China's Spatial Panel Data
Authors: Wang Yukai , Liu Sheng
Published: October 2022

With the rapid development of information technology and transportation, will industrial co-agglomeration present spatial spillover effect on the upgrading of global value chain? This paper studies the effect of co-agglomeration of producer services and manufacturing on the upgrading of global value chain, especially its spatial spillover effect. Results show that a significant spatial correlation exists in the upgrading of global value chain in Chinese cities, and the trends of geographical agglomeration and spatial correlation of the function links of global value chain are strengthened. Furthermore, the co-agglomeration of inter industries has a significant spatial spillover effect on the upgrading of global value chain, which shows that the spatial synergy effect of China's urban secondary and tertiary industries is gradually emerging. Moreover, compared with external radiation spillover effect, the local spillover effect is more obvious, which suggests the significance of constructing mechanism of cross regional industrial cooperation. To accelerate the industrial integration and spatial connection, it is necessary to build a new pattern of multipolar network space development, and strengthen the spatial externality of service provision as well as the upgrading of global value chain.

Fiscal Decentralization, Export Technology Complexity and Regional Green Total Factor Productivity: Empirical Study based on GML Productivity Index
Authors: Lin Xiao , Liu Sheng
Published: October 2022

With the Global-Malmquist-Luenberger (GML) productivity index, we calculate and evaluate the Chinese green total factor productivity and the decomposition, and further take the dynamic GMM method to empirically study the effect of export sophistication, fiscal decentralization and their interaction terms on regional green total factor productivity. The increasing export technology complexity has a significant effect on the regional green total factor productivity growth. Increasing export sophistication degree means the improving status of international vertical specialization division and upgrading of export product structure, which has a positive incentive effect on adoption of regional environmental technology and transformation and upgrading of regional industrial structure. However, this effect will be disturbed by the regional fiscal decentralization. Fiscal decentralization intensifies local government’s competition and distorts local factor market and resources misallocation. It will  not only distort the incentive of enterprises to increase less technology and the R&D on the export of products, but also will inhibit the upgrading process of regional industrial structure, which would lead to extensive growth trap of “high consumption and high emission”. To continue to enhance China's position in the international division of labor is necessary. Moreover, a diversified evaluation system is encouraged in the performance evaluation system of local officials to optimize the resources allocation efficiency, and propose a proper guidance and incentive for local enterprises to promote industrial transformation and upgrading. Ultimately a win-win situation between ecological civilization construction and economic sustainable growth is achieved.
Coordination and Optimization of Supply Chain Considering the Double Fresh-keeping Effort of Supplier and 3PL
Authors: Li Chang
Published: October 2022

This paper takes a three-echelon supply chain consisting of a domestic supplier, an overseas retailer, and an overseas warehouse as the research object, and studies the decision-making and coordination problems of a single-channel three-echelon supply chain dominated by a cross-border e-commerce platform based on the dual preservation effort level of the supplier and the overseas warehouse, and also analyzes and compares the optimal decisions and profits of each member of the supply chain under the decentralized decision-making model and the centralized decision-making model. After exploring the infeasibility of wholesale price contract and wholesale price + cost-sharing contract, a wholesale price + cost sharing + revenue sharing hybrid contract is designed to optimize the coordination of the supply chain and finally examined and verified through arithmetic analysis. It is found that it is difficult to judge the overall utility of consumers under centralized decision-making, and the decisions made under decentralized decision-making are not optimal. Under the decentralized decision-making model, the wholesale price contract, and the wholesale price + cost-sharing contract can achieve supply chain coordination, but the contract will not be accepted because the former hurts the members' interests, and the latter reduces the overall profit. Therefore, a hybrid "wholesale price + cost sharing + revenue sharing" contract is designed to introduce profit redistribution and is shown to achieve perfect supply chain coordination.
The Integration of Marxism and Chinese Traditional Culture
Authors: Lu Jingsi
Published: October 2022

Since Marxism was introduced into China, the combination of Marxism and Chinese traditional culture has always been an important topic of the Sinicization of Marxism. With the upsurge of traditional Chinese culture, some people advocated the return to the era of Confucianism and the need to abandon the guidance of Marxism; some people believed that adhering to the guidance of Marxism should abandon traditional culture. Obviously, these two extreme views are not desirable, and both are harmful to China's development. The reason for the above is that people's understanding of Marxism and traditional Chinese culture is vague or even wrong. Only by solving how to better integrate Marxism and traditional Chinese culture can we provide guidance for China's development. The necessity, possibility and mutual benefit of fusion with Chinese traditional culture are discussed to discuss the fusion of Marxism and Chinese traditional culture.

Authors: Qu Guohui , He Weizhong , Zhang Zilu , Tian Xuebin , Li Bowen , Li Xiunan , Liu Yikun
Published: October 2022

Through field geological survey and drilling exploration in Sanjiang Basin, combined with geochemical analysis, the tectonic thermal evolution history of intrusive rocks is studied. The results show that the Early Mesozoic siliceous rocks in Qianjin Depression of Sanjiang Basin are widely distributed. The siliceous rocks are of post diagenetic hydrothermal metasomatic origin, and the hydrocarbon source rock indicators are good, which is expected to be a new formation for oil and gas exploration in Sanjiang area. The time temperature thermal history simulation of fission track shows that there have been two rapid cooling events (late Early Cretaceous Late Cretaceous and Paleocene Eocene) in the Nadanhadaling area since the Mesozoic era, with cooling rates of 3.42~4.81 ℃/Ma and 1.43~1.83 ℃/Ma, respectively. The two rapid cooling processes were caused by the subduction of the Pacific plate. The rapid cooling during the Early Cretaceous to the Late Cretaceous was caused by the change of the subduction direction of the Pacific plate and the collision and superposition of the Okot Motsk block and the East Asian continental margin; The rapid cooling from Paleocene to Eocene was mainly caused by the subduction and retreat of the Pacific plate, which made the East Asian continental margin in an extensional environment and caused denudation and cooling in most parts of Northeast China.

The identification, positioning and grabbing path planning of table tennis balls are the preconditions for the robot to pick up table tennis balls autonomously. A method of table tennis identification, positioning and grabbing path planning based on monocular vision image processing is proposed. By analyzing the characteristics of table tennis images, a table tennis image segmentation method based on color and contour features is designed. The color and contour features of table tennis images are extracted, and HSV is used for image preprocessing. Image segmentation is processed by binarization, and Hough circle is used to detect contour recognition, and the segmentation image of table tennis balls is obtained by color combination. Convert the camera imaging coordinates to obtain the pixel position of the table tennis ball in the image. A ball picking path planning based on ant colony algorithm is designed. This paper provides a theoretical reference for the identification, positioning and path planning of autonomous ball picking.

Authors: Bokhari Syeda Samar Shahid
Published: October 2022

The present research study aims at enhancing the intellectual acumen of the students by devising various strategies of teaching poetry. In order to understand poetic text, the students need to delve deep into its meaning by focusing on the poetic language.Teaching poetry is the best tool for the literature students to harness their mind at their full stretch in creating deeper understanding of what they are reading. The researcher has selected Robert Frost for the purpose, as his poems are full of figurative language that if understood well could tune the minds of the students for further explorations into the poetical structures. Not only it would increase their mental level of understanding of this beautiful genre, but they would also learn to look at life through a different angle. Focus was on the two main thematic poetical compositions of Robert Frost: a) Stopping by Woods on a Snowy Evening, and b) Mending Walls. Both of these poems have underlying thoughts and expressions. Frost's poetry is enjoyable when read thoroughly while concentrating on the poetical diction and the inner meanings. This study through specially designed Research Instrument studies the change of perspective of college students studying English Literature.A sample of 50 students was taken and they were taught poetry of Robert Frost with special attention on the figurative language employed. Their understanding level was gauged through tests and some encouraging factors emerged to make the study a model for all the Teachers of English Literature and Language.
