Can pilot free trade zones policy force the green transformation of enterprises? Evidence from listed companies in China.

In order to reveal the impact of pilot free trade zones policy on green development, we use multi-period difference-in-difference estimation and fixed effect model to explore the impact and impact mechanism of the establishment of free trade zones on the green transformation of enterprises from the micro perspective, based on the panel data of China's A-share listed companies from 2009-2021, The results show that pilot free trade zones policy significantly improves the green transformation of enterprises in the zones. Pilot free trade zones policy affects the corporate green transformation through industrial agglomeration and financial constraints. The green transformation of state-owned enterprises, non-heavy polluting enterprises and high-tech enterprises are significantly impacted by pilot free trade zones policy. Urban innovation and green subsidies play a positive moderating role in the impact of free trade zones on enterprises' green transformation. The research conclusions provide a valuable policy basis for how to promote the green transformation of enterprises under the free trade zones policy.

How does the communication infrastructure quality of the countries along the "Belt and Road" effect the equipment export of China?

Under the influence of COVID-19 in the past few years, the world has been facing tremendous changes. The world economy is also facing strong headwinds on its path toward recovery, and global development has suffered major setbacks. Under this background, China's equipment export has also been greatly affected. In order to maintain a stable export of equipment manufacturing to the "Belt and Road" countries, this article constructs an extended gravity model with communication infrastructure variables using the statistical data of China's equipment manufacturing exports from 2010 to 2020 and discusses the impact of "Belt and Road" countries' communication infrastructure quality on China's equipment manufacturing exports by product and country heterogeneity analysis. The results indicate significant differences in the quality of communication infrastructure among countries along the "Belt and Road". Overall, the improvement of "Belt and Road" countries' communication infrastructure quality can promote the export of China's equipment manufacturing industry. Except for the electrical machinery and office instrument, the quality improvement of "Belt and Road" countries' communication infrastructure has a positive effect on other subdivision products of China's equipment manufacturing industry, but the intensity of the effect is heterogeneous. The improvement of transition economies' communication infrastructure quality significantly promotes the export of China's equipment manufacturing industry, but the developed and developing economies' promotion effect is not significant.
