长三角区域市场的地区分割——基于边界效应模型的分析

改革开放以来,我国地方市场分割问题一直比较突出,而建立全国统一开放的市场是我国经济转轨中最重要的目标之一。如何实现经济协调发展是我国当前急需解决的一个重大问题。基于此目的,本文构造了一个以边界效应模型为基础的分析框架,以长江三角洲八城市的行业部门为样本,进行实证检验。通过投入产出法计算得到行业之间的边界效应值。结果表明,在长江三角洲地区诸多的行业中市场分割与地方保护仍然比较严重。因此,长江三角洲并未实现真正的市场一体化。

Market Segmentation in the Yangtze River Delta Region--Based on the Analysis of the Border-effect Model

Since the beginning of reform and opening up,China has been more prominent local market segmentation,and to create a unified national market,opening up of China's economic transformation is one of the most important objectives.How to achieve coordinated economic development is a major issue for urgent solution.For this purpose,this paper chooses the "Border Effect" model as the framework.Using data for the 8 cities in Yangtze River Delta,the paper estimates large integrating effects in the process of regional integration with the way of "input and output".Furthermore,the paper finds it that the market segmentation also exists.The real integration of Yangtze River Delta is not founded.
