Authors: Li Shuxia , Liu Zhiying , Fang Huiming , Liu Liping 
Published: December 2019

Abstract
The vehicle routing problem of fresh agricultural products is different from ordinary goods due to their perishability. Therefore, we are concerned with the impact of the decaying factor on the total distribution cost and delivery routes when delivering multiple fresh agricultural products simultaneously. Based on the fact that customers often want to receive products within the expected service times, this paper proposes a multi-objective VRP optimization model for multiple fresh products to minimize both transportation costs and variance of loss quantity of fresh agricultural product. An ant colony algorithm is proposed and implemented on MATLAB to solve a given VRP problem. The impact of different exponential decaying rates and weight coefficients on the total distribution cost and the variance of loss quantity are discussed to draw managerial insights. Results indicate that suppliers need to sacrifice some benefits to improve customer satisfaction.

Published: December 2019

Abstract
The mining of IC card data for commuters’ classification and analysis of bus route choice plays an important role for public transport passengers’ choice behavior analysis, and formulating a scientific and reasonable traffic planning strategy. The authors choose some indicators for passengers’ classification in Beijing and use classification and regression tree model to build the classifier. Three parameters: departure time, travel distance and travel frequency, as the classification parameters, are input into the model and the results show 45 classification passengers; Among them, strong commuting passengers accounted for 7.25%, weak commuting passengers accounted for 30.27%, and accidental commuting passengers accounted for 62.48. This paper also analyzes the characteristics of the public transport route choice for all classification groups from four aspects: the overall characteristics, transfer characteristics, travel characteristics and subway travel characteristics. The conclusions of this paper can provide a theoretical basis for the analysis of passenger flow composition of multimodel public transport and the establishment of multi-mode bus route selection model.

Authors: Shen Jian , Wu Lang 
Published: December 2019

Abstract
Based on the non-inertial reference system, the vehicle model of four freedom degrees is used to establish the vehicle-bridge coupling dynamic system model of the curved beam in space. Considering the vehicle-bridge coupling vibration characteristics under the non-uniform seismic excitation at the two supports of the bridge, the three-dimension space curvilinear-vehicle coupling dynamic control equation is established based on the Hamiltonian principle. Then the coupling dynamic control equation of the vehicle and bridge is numerically analyzed by the method of separating variables.

Published: December 2019

Abstract
At the same time of large-scale development of trunk railway and urban rail transit, Regional Railway will gradually enter the stage of large-scale construction. Post-station turn-back is one of the most frequently used forms for regional railways, the length of turn-back line and safety distance directly affects the scale of station and construction investment. However, the provision for safety distance of turn-back line is relatively broad in the current design specifications, and there is margin for further refinement. Based on the safety braking model, starting from the fundamental reasons for setting the safety distance, this paper studies the calculation method of safety distance and turn-back capability by analyzing the factors affecting the safety distance. Combining with the actual operation requirements, considering both train operation safety and turn-back capacity, the optimal safety distance model of turn-back line is constructed by selecting the post-station turn-back. The actual station is analyzed and the research results have positive significance.
CSTM: Cluster-based Security Trust Mechanism for VANET
Authors: Wang Jijin , Xiao Xiaoqiang , Peng Lu 
Published: December 2019

Abstract
Vehicular Ad hoc Network (VANET) allows communications between vehicles and roadside infrastructure. Various information can be propagated by the vehicles to ensure the safety and security of the driver and passengers by reducing the transport accidents and traffic congestion, besides, VANET communication can also provide navigation and entertainment service. However, the existence of the malicious nodes results in falsified and modified messages which could affect the performance of the network and even worse, could cause dangerous situation: accident, collision, traffic congestion, etc. In order to ensure the security and stability of VANET communication, we can introduce the concept of trust and improve the credibility of communication between vehicles through trust management. Therefore, this paper proposes a cluster-based security trust mechanism for VANET. By grouping vehicles with the same speed attribute into clusters, the network topology tends to be stable, and the information credibility and node reputation value are calculated by the cluster head, to determine the authenticity of the event message.

Research on Application Technology of Molybdenum Tailings Sand Concrete
Authors: Chen Xiaobin 
Published: December 2019

Abstract
Molybdenum tailings sand is used as a fine aggregate to replace part of the construction sand, which can effectively solve the environmental pollution problems caused by the molybdenum tailings pond and has high utilization value. After tetsting the physical properties, chemical analysis, radioactivity and other indicators of molybdenum tailings sand, the results show that the molybdenum tailings sand basically meets the conditions of construction sand. By increasing the proportion of molybdenum tailings in concrete, the concrete performance will decrease in viscosity, slump loss and strength with the increase of the blending ratio. Therefore, the ratio of molybdenum tailings to substitute fine aggregate is between 40%-50%, should not exceed 60%. The problems of viscosity and strength of molybdenum tailings sand concrete still need to be solved through adjusting the concrete mix proportion or optimizing the admixture formula.
Research on the relationship between institutional investor heterogeneity and corporate environmental responsibility
Authors: Shen Chen 
Published: December 2019

Abstract
Taking Shanghai and shenzhen a-share listed companies from 2010 to 2016 as samples, this paper empirically studies the impact of institutional investor ownership on corporate environmental responsibility. The heterogeneity of pressure-sensitive institutional investors and pressure-resistant institutional investors is distinguished, and the influence of marketization process on institutional investors’ participation in corporate environmental responsibility is further discussed. The results show that the total shareholding of institutional investors is negatively correlated with the level of corporate environmental responsibility. Compared with pressure-resistant institutional investors, pressure-sensitive institutional investors’ shareholding is more detrimental to enterprises’ undertaking of environmental responsibilities. The faster the marketization process in the region, the more the negative effect of pressure-resistant institutional investors on corporate environmental responsibility will be weakened, while there is no significant regulating effect on the relationship between pressure-sensitive institutional investors and corporate environmental responsibility.

Will industrial restructuring under the infrastructure sector promote local governments to adopt the PPP model?
Authors: Liu Yujie 
Published: December 2019

Abstract
Based on the panel data of the industrial structure of 31 provinces (cities, autonomous regions) in China from 2007 to 2017, this paper studies the relationship between local government’s choice of PPP financing and industrial structure and regional attributes. The study found that the advanced industrial structure has a restraining effect on the choice of PPP mode for local governments in the infrastructure sector. Further research after adding regional attributes shows that the attributes of the central and western regions have different effects on the selection of PPP mode. This paper believes that the industrial structure is an important factor for the government to use the PPP model for financing. Therefore, local governments should fully consider the impact of regional industrial structure when conducting infrastructure investment and financing.

Abstract
This research uses the SBM-DEA model to measure the economic efficiency and eco-efficiency of the cities in China’s five major urban agglomerations of the Beijing-Tianjin-Hebei urban agglomeration, the Yangtze River Delta urban agglomeration, Middle Reaches of the Yangtze River, the Pearl River Delta urban agglomeration and the Chengdu-Chongqing urban agglomeration in 2007-2016, and further analyzes the factors affecting eco-efficiency by using the Tobit model. The results show that: (1) The economic efficiency of the five urban agglomerations is at a medium to upper level. The economic efficiency among urban agglomerations still shows some differences, but the efficiency gap has shrunk. (2) The eco-efficiency of the five urban agglomerations is slightly lower than the economic efficiency, and the difference of the two efficiencies has significantly expanded after 2011. Eco-efficiency still shows significant regional difference among urban agglomerations. The nuclear density curves of five urban agglomerations show different distribution states and development trends. Environmental pollution is the determining factor for the eco-efficiency of the five urban agglomerations. (3) From the perspective of factors affecting eco-efficiency, economic development, industrial structure, investment in science and technology, environmental regulation, and population size have different effects on the overall and different urban agglomerations.

Authors: Wang Ruiting 
Published: December 2019

Abstract
Electric vehicles are more economic and environmentally friendly, but they are still not widely accepted by citizens in China. This paper makes a detail study on factors influencing consumers’ attitude of electric vehicles by analyzing 2769 online reviews, aiming to point out authentic assessment from the actual EV users. Firstly, we build the comment thermodynamic chart based on the review quantity and find the comment quantity reflects the sales to some extent, and the sales amount is positive relevant to regional policies quantity. Secondly, we calculate the correlation among space, manipulate, power-consumption, power, trim, comfort, appearance, cost-performance and mainly analyze how the first seven performance influences the cost-performance. Thirdly, we study the purchase purpose, finding that for EV users, they choose EVs mainly for daily short-distance running. These findings can not only help consumers for their consumption choice, but also guide EV manufacturers about their further technology focus in a certain degree.
A research on the correlation between internal control quality and financial performance
Authors: Gao Junxin 
Published: December 2019

Abstract
We select 1931 Shanghai and Shenzhen A-share listed companies and 9655 groups of data during 2012-2016 as the research sample. Then we use DIB China listed company internal control index as the measure of internal control quality. We also establish a comprehensive financial performance index from debt-paying ability, operation capacity, profitability and development ability to evaluate financial performance. Next we empirically study the correlation between internal control quality and financial performance in accordance with the total samples and the industry samples. We find that internal control quality is significantly related to corporate financial performance on the whole. However, the influence is different between different industries and the correlation in technology-intensive industries is greater than that in capital-intensive industries and labor-intensive industries.

Published: December 2019

Abstract
In the low-carbon background, the green manufacturing and a new road to industrialization should be developed in China. Government subsidies can promote the promotion of low-energy products, and thus control the total carbon emissions. Aiming at an innovation-decision dilemma of a kind of self-research and development manufacturing firms, the characteristics of disruptive innovation and sustaining innovation were analyzed in the viewpoint of the firms’ dynamic competitive advantages. A 0-1 nonlinear decision model was built with consumer surplus as the optimization objective. This model can provide guidance for government policy strategy and manufacturing firm innovation decision. A genetic algorithm was developed to solve the 0-1 nonlinear decision model. A case study of an automobile was reported to demonstrate the feasibility and rationality of this approach.
