中文摘要:利用双边随机前沿方法，基于2006-2019年省际面板数据测算电子商务发展的市场整合效应、市场分割效应及净效应大小。研究发现：电子商务发展的市场整合效应为28.13%，市场分割效应为16.24%，二者共同作用最终使得市场分割程度下降11.89%；电子商务在整合国内市场上存在规模不经济，随着电子商务发展水平的提高，其市场整合效应呈倒“U”型趋势，市场分割效应则有所增强，致使其整合市场的净效应随电子商务发展水平的提高而减弱。

E-commerce Development and the Domestic Unified Market: Integration or Segmentation ——Based on the Bilateral Stochastic Frontier Model

Abstract:Based on the inter-provincial panel data from 2006 to 2019，this paper uses the bilateral stochastic frontier method to calculate the market integration effect，market segmentation effect and the net effect of E-commerce development . The results show that the market integration effect of E-commerce development was 28.13%，and its market segmentation effect was 16.24%. The combined effect of the two ultimately reduced the degree of market segmentation by 11.89%. E-commerce has diseconomies of scale in the integration of the domestic market. With the improvement of the development level of E-commerce，its market integration effect presents an inverted “U” trend and the market segmentation effect has increased，causing the net effect of integrating the market weaken as the level of E-commerce development increases.
