Background: As human beings enter the digital age, the impact of the digital economy on environmental regulation and corporate green technology innovation (CGTI) is expanding. In order to effectively strengthen the efficacy of environmental regulation and improve the green technology innovation ability of corporate, this paper conducts in-depth research on the influence process of the digital economy and environmental regulation on the CGTI. Methods: Based on the mediating variable environmental regulation, this paper explores the influence process of the digital economy on CGTI. Combined with empirical analysis methods such as the fixed-effect model, mediating effect model, spatial model and regression analysis, the authors reveal the influence process of the digital economy on CGTI. Results: The digital economy can directly promote the improvement of the green technology innovation level of CGTI. The digital economy can indirectly affect the CGTI through the mediating variable of environmental regulation, marginal effect and spatial spillover effect. Conclusions: The digital economy and CGTI had a significant spatial correlation among different regions in China. In different regions of China, there are significant differences in the relationship between the digital economy, environmental regulation and CGTI.

Combining the theories of cross-border e-commerce trade, industrial cluster management, coordinated development, and sustainable development, this paper explores the problem of the coordinated development path of China’s cross-border e-commerce trade and industrial clusters. The research purpose of this paper is to propose relevant suggestions to promote the sustainable coordinated development of cross-border e-commerce trade and industrial clusters by revealing the inherent scientific laws of the sustainable coordinated development of them. By using a literature survey method, structural equation method, and system analysis method, on the basis of constructing a model for the coordinated development of cross-border e-commerce trade and industrial clusters, this paper conducts in-depth empirical analysis combined with relevant research data and draws research conclusions. The research conclusions of this paper are as follows: (1) This paper verifies all the research hypotheses proposed. All the research hypotheses proposed in this paper are supported by valid data and have passed the empirical test. (2) Using data to scientifically prove that there is an obvious positive correlation between cross-border e-commerce trade and industrial clusters. (3) There is an obvious positive interaction between the main components of cross-border e-commerce trade and the main components of industrial clusters. Moreover, under the influence of the external environment, the two component systems can also promote the sustainable coordinated development of cross-border e-commerce trade and the sustainability of industrial clusters. (4) This paper puts forward countermeasures and suggestions to promote the sustainable coordinated development of cross-border e-commerce trade and industrial clusters.

The impact of international electronic commerce (IEC) on export trade increases along with its expanding scale. Based on relevant data and the gravity model of China’s IEC export trade, this paper develops a theoretical model that can be used in IEC scenarios, applies regression equations, a Hausman test, and other empirical methods to verify relevant data, and performs a robustness test. The purpose of this paper is to explore the mechanism of IEC impact on China’s trade, and hopefully to study the temporal structural changes of the impact of IEC activities on China’s export trade based on the financial crisis and European debt crisis variables. The innovation of this paper is mainly reflected in the large sample of China’s trade selected in this paper. It can also determine the changes in the distance effect of international trade in the era of IEC, and reveal the mechanism by which IEC applications help foreign trade enterprises overcome economic crises. Four key conclusions are obtained as follows. First, the development of IEC has significantly promoted the expansion of China’s export trade scale. Second, in the context of the global financial crisis and European debt crisis, the positive promotion effect of IEC on exports is not significant. Third, the promotion effects of IEC on China’s exports to both developing and industrialized countries are significant, with the impact on developed country exports being slightly greater. Fourth, although the geographical distance for measuring transportation costs has a negative effect on China’s exports, such effect has been greatly weakened.
