市场一体化对出口技术复杂度的影响——基于西部陆海新通道沿线地区的研究
The Impact of Market Integration on the Export Sophistication—A Study Based on the Areas along the New Western Land-Sea Corridor

本文基于西部陆海新通道沿线地区市场一体化的研究视角，从理论上分析了市场一体化对出口技术复杂度的影响机制，并利用2010~2020年12个省市(剔除西藏)的面板数据，从实证上验证了理论分析。研究结果表明：西部陆海新通道沿线地区的市场一体化水平会显著提升当地的出口技术复杂度，这与预期结果一致。而基础设施、研发投入和金融发展均对沿线地区出口技术复杂度起着积极的作用。沿线地区的外商直接投资强度和质量不高，不足以对出口技术复杂度造成影响。在西部陆海新通道上升为国家战略的背景下，本文的研究结论对推动西部地区形成一体化市场，引领西部地区协调发展和实现西部对外开放新格局具有深远意义。
Based on the research perspective of market integration in the areas along the new western land-sea corridor, this paper theoretically analyzes the influence mechanism of market integration on export sophistication and empirically verifies the theoretical analysis using panel data of 12 provinces and cities (excluding Tibet) from 2010 to 2020. The findings show that the level of market integration in the areas along the new western land-sea corridor significantly enhances the local export sophistication, which is consistent with the expected results. Infrastructure, R&D investment and financial development all play a positive role in the export sophistication of the areas along the route. The intensity and quality of foreign direct investment in the areas along the route are not high enough to have an impact on export sophistication. In the context of the rise of the new western land-sea corridor as a national strategy, the findings of this paper have far-reaching implications for promoting the formation of an integrated market in the western region, leading the coordinated development of the western region and realizing a new pattern of opening up the western region to the outside world.
