From the perspective of the implementation of China's cross-border e-commerce industrial policy, this study empirically tests the impact of cross-border e-commerce industrial policy on the quality of agricultural products exported by China through using the HS6-digit export data in CEPII-BACI database from 2006 to 2020 and adopting the Difference-in-Difference method. The research shows that the cross-border e-commerce industrial policy has a significant positive impact on the quality of agricultural products exported by China. The study also found that there is significant heterogeneity in the impact on agricultural products exported from different regions and with different quality levels. Finally, the mechanism test conclusion shows that cross-border e-commerce mainly promotes the improvement of export quality of agricultural products exported by China through export competition effect and export learning effect.
Reduction of regional trade policy uncertainty is critical for promoting Chinese export enterprise productivity and will help the economy enter the high-quality development stage. We use the case of the China-ASEAN Free Trade Area to empirically tests the impact of the reduction of regional trade policy uncertainty on the productivity of Chinese export enterprises. We apply the difference-in-difference method to micro-enterprise level data from the "China industrial enterprise data-
We propose a theoretical framework to illustrate the impact of trade policy uncertainty on pollution emissions of export enterprises and the underlying mechanism. The magnitudes of the effect and the proposed channels are empirically estimated using the case of the formal establishment of China‐ASEAN free trade area and sulfur dioxide (SO2) emission intensity as a measure of pollution emission intensity. Our analysis relies on high‐precision micro enterprise‐level data and the difference‐in‐difference methodology. The results show that China‐ASEAN free trade area effectively reduced the trade policy uncertainty and the SO2 emission intensity of Chinese enterprises exporting to ASEAN. The study also shows that the export enterprises of different trade modes, ownership types, regions, factor intensity, and pollution intensity industries show significant heterogeneity in the extent of the reduction in the SO2 emission intensity. The mechanism test reveals that the trade policy uncertainty decline mainly reduces the emission intensity of SO2 by raising the competitive and learning effects. The contribution of the learning effect is higher and accounts for 32.54% of the total effect. In addition, through dynamic decomposition at the industry level, we found that the contribution rate of resource allocation effect among enterprises in reducing the total emission intensity of SO2 of enterprises exporting to ASEAN at the industry level is 52.22%. This effect is perhaps the most significant way trade policy uncertainty impacts the SO2 pollution emission intensity.
