中国区域经济增长的β趋同分析

β Convergence Analysis of China's Regional Economic Growth

随着我国对外开放和市场化改革的不断深入,区域间经济发展差距日益扩大,区域协调发展成为我国区域政策的主要内容,经济增长收敛性问题也因此成为学界关注的焦点。基于Barro和Sala-I-Martin(1992)经济增长趋同理论的实证分析表明,中国省域和城市的经济增长不存在绝对β趋同,而是存在增长趋异,但在控制工业化、信息化、城市化、市场化和开放化等变量条件下,却表现为条件β趋同。由此表明,实现区域协调发展,应加大对欠发达地区的支持力度,做好发达地区与欠发达地区间的产业转移与承接和产业结构调整工作,细化区域政策至城市单元级。

With the deepening of opening up and marketization reform in China, regional economic gap is widening and the coordinated development has become the main content of regional policy. Thus economic convergence problem has become the focus of academic circles. On the basis of convergence theory of economic growth presented by Barro and Sala-I-Martin （1992）, the empirical analysis shows that China＇s provincial and urban economic growth doesn＇t exist absolute β convergence but growing divergence. However, under the control of industrialization, informatization, urbanization, marketization, opening and other variables, there exists conditional β convergence. Therefore, the government should enhance the support to less developed areas, accomplish industrial transfer and undertake and the adjustment of industrial structure between developed regions and less developed regions, and refine regional development policy to urban level.
