Under the background of high-quality development, the e-commerce industry needs to seek more comprehensive development, and the logistics industry should not only maintain higher efficiency, but also meet the requirements of green and low-carbon transportation. This study aims to investigate the link between the logistic density and the proportion of e-commerce transaction scale. There are few studies on how logistics density affects the development of e-commerce quantitatively. In order to solve this gap, this study establishes an impact model of high-quality growth of e-commerce, and based on Solow production model, constructs a calculation method of logistics density, and analyzes the impact mechanism of logistics density on the scale ratio of e-commerce transactions. Using the bidirectional fixed effect model, this paper makes an empirical analysis of the panel data of 31 provinces consisting of 248 observations and autonomous regions in China from 2014 to 2020. The results show that logistic density has a positive and significant impact on the growth of e-commerce, thus promoting the optimization of economic structure. The acceleration of logistics density decreases the expansion of the ecommerce. Finally, there are obvious regional differences between the development of e-commerce and logistics infrastructure in China. Finally, based on the empirical result, this paper puts forward recommendations for government and companies.

The Belt and Road Initiative (BRI) is a development plan proposed by China that aims to build a new platform for international cooperation and create new drivers of shared development. South Asia is a key area in the Belt and Road Initiative, including eight countries. As the BRI implemented, China’s trade with South Asia has been gradually strengthened. This paper explores the influencing factors of China-South Asia trade under the background of the BRI by using Gravity Model of Trade. The results show that economic growth in China and South Asia, increase of savings rate and improvement of industrialization in South Asia has a significant positive effect on China-South Asia trade. While the development gap between China and South Asia has negative effect on China-South Asia trade.
