市场一体化与区域协调发展

Domestic Market Integration and Regional Coordinate Development

消除地方市场分割、建立完善全国统一开放的市场是否有利于区域经济的协调发展?本文从理论和实证两个方面展开讨论。在理论上,我们构造了一个简单可行的旨在考察地方市场分割(市场一体化)影响区域经济协调发展的分析框架。在实证上,以1990—2002年间的长三角城市群为样本,作者发现,随着长江三角洲城市经济协调会的成立、运行,地方市场分割对区域协调发展的阻碍作用已经下降了近50%。本文的发现是稳健的,有助于进一步增进对如何实现区域协调发展的理解。

The paper attempts to explore the integrating effects of domestic market in the process of the regional coordinate development. Theoretically, the paper generalizes the conditional β convergence framework to incorporate the integrating effect into the famous Barro Regression Equation. Using data for cities in Yangtze River Delta, the paper estimates large integrating effects in the process of regional integration, and also documents this effect is more and more significant. Furthermore, the paper finds the development in Shanghai has been benefiting the regional coordinate development in Yangtze River Delta since the late 1990s. These findings are robust, and may shed some highlights on how to implement the coordinate development in China.
