【摘要】：本文基于金融发展的视角,通过构建数理模型考察了国内市场一体化影响出口技术水平的微观机制。在此基础上,采用工具变量两阶段最小二乘法(2SLS)进行深入的实证检验。研究结果表明:国内市场一体化显著且稳健地提高了中国地区出口技术水平,而且在金融发展水平越高的地区,国内市场一体化对地区出口技术水平的促进作用越大,即国内市场一体化与金融发展是相互强化发挥作用的。进一步的估计显示,在金融控制强的区域,金融发展对地区出口技术水平的促进作用并不明显;而在金融控制弱的区域,金融发展则显著地提高了地区出口技术水平。此外,金融控制弱区域的国内市场一体化对出口技术水平的边际影响效应也远远高于金融控制强区域。本文的研究意味着,降低金融控制程度不仅可以直接提高金融发展对地区出口技术水平的影响效应,而且还间接地提升国内市场一体化对地区出口技术水平的促进作用。
[Abstract]:Based on the perspective of financial development, this paper investigates the micro mechanism of domestic market integration affecting export technology level by constructing mathematical model. On this basis, the tool variable two-stage least square method (2SLS) is used to carry out an in-depth empirical test. The results show that the integration of domestic market has significantly and steadily improved the level of regional export technology in China, and the higher the level of financial development, the greater the promotion of domestic market integration to the level of regional export technology. That is, domestic market integration and financial development are mutually reinforcing to play a role. Further estimates show that in the regions with strong financial control, the role of financial development in promoting the technical level of regional exports is not obvious, while in the regions with weak financial control, the financial development has significantly improved the level of regional export technology. In addition, the marginal effect of domestic market integration on export technology level is much higher than that of strong financial control region. The research in this paper means that reducing the degree of financial control can not only directly improve the effect of financial development on regional export technology level, but also indirectly promote the promotion of domestic market integration to regional export technology level.
