基于DEA方法,本文从边际集聚效应和边际集聚成本角度解释了集聚效率,运用1999-2008年中国省级面板数据测算区域集聚效率,并运用动态面板模型对影响集聚效率的相关因素进行了回归分析。研究表明:东部地区的集聚效率经历了先升后降再上升的变化过程,中部地区的平均集聚效率在逐步提高,西部地区的平均集聚效率在逐步减小;上一期的区域集聚效率水平、区域基础设施水平、区域对外开放水平和创新能力对提升区域集聚效率具有显著促进作用,固定资产投资阻碍了区域集聚效率水平的提升,政府财政支出和区域产业结构变化对集聚效率影响均不显著。
Based on the DEA method, this paper explains the agglomeration efficiency from the perspective of marginal agglomeration cost and marginal agglomeration cost, and calculates the regional agglomeration efficiency using the provincial panel data from 1999 to 2008 in China. The dynamic panel model is used to analyze the factors that affect the agglomeration efficiency . The results show that the agglomeration efficiency in the eastern region has experienced a process of first rising, then falling and then rising. The average agglomeration efficiency in the central region is gradually increasing while the average agglomeration efficiency in the western region is gradually decreasing. In the previous period, the regional agglomeration efficiency, The level of regional infrastructure, opening up to the outside world and ability to innovate have a significant role in promoting the efficiency of regional agglomeration. The investment in fixed assets has hindered the improvement of the efficiency of regional agglomeration. The changes in government fiscal expenditure and regional industrial structure have no significant effect on agglomeration efficiency.
