The 3rd Plenary Session of the 18th Central Committee of the Party is a milestone in the important stage of China's efforts to build a moderately prosperous society in all respects and deepen reform and opening up in an all-around way. The modernization goal for the national governance system and capacity mentioned the Session establishes the important role of social organizations in governance. With the goal of modernized national governance system and capacity in mind, we should boost the reform and development of social organizations.
In 2020, the cross-border e-commerce industry suffered a setback against the backdrop of the global epidemic. In the context of the global epidemic and economic structural reform and transformation, China has proposed a new economic pattern of "dual circulation" development, and this measure has greatly promoted the development of China's cross-border e-commerce industry. According to relevant data, the export share of China's cross-border e-commerce accounted for 77.6% of its market size in 2020. As a result, this paper studies the influence of the "dual circulation" measure on the development of cross-border e-commerce B2B export trade and classifies and analyzes the policies related to the cross-border e-commerce industry in the "dual circulation" measure. Then, a system dynamics model reflecting the lag effect of this measure on cross-border e-commerce B2B export is also constructed, and the effects of different single policies and different policy combinations on cross-border e-commerce B2B export are simulated successively. The modeling process and simulation results demonstrate that: (1) infrastructure investment of cross-border e-commerce is most affected by policy lag, followed by government supervision and enterprise operation, while talent training of cross-border e-commerce and customs supervision are almost not affected by policy lag; (2) tax policy, customs clearance policy, and fiscal policy have greater effects on the promotion of cross-border e-commerce B2B exports, while the payment policy and talent policy have less impact on them; and (3) from the simulation results of policy combination, it can be seen that the regulatory environment (i.e., regulatory policies) is the most important to promote cross-border e-commerce B2B export trade, followed by financial support, customs environment, and business environment. Finally, this paper gives suggestions for the formulation of relevant government policies to promote the development of cross-border e-commerce B2B export trade and provide some reference values for other governments to develop the cross-border e-commerce B2B export trade industry.
The ecological environment of China is facing much more pressure with the continuous growth of population and energy usage. China pays more attention to improving the ecological environment quality with the ecological civilization development in the situation. The key problem is to construct a scientific and reasonable comprehensive evaluation index system guiding the ecological environment quality improvement. This paper creates a comprehensive evaluation index system of ecological environment quality based on the Pressure-State-Response (PSR) framework and uses a hybrid model with the entropy weight method and matter-element extension to evaluate China's ecological environment quality from 2016 to 2020. The results show the overall ecological environment quality evaluation level in China is continuously improved. The results also show that China should pay much attention to the four main factors, which are population density, carbon emissions, per capita energy consumption, and per capita arable land, it should take some policies to improve the four factors. The case study has proven the effectiveness and practicality of the hybrid method and the comprehensive evaluation index system.
