中国市域工业集聚的空间效应及影响因素

The Spatial Effect and Influencing Factors of Industrial Agglomeration In China

经济集聚已成为现阶段经济增长的普遍性特征,它对中国区域和城市经济发展具有重要作用。首先,基于中国市域面板数据,揭示当前中国市域工业集聚的空间效应;其次,建立比较优势战略、新经济地理、经济政策等因素与工业集聚的实证分析框架,并采用动态空间面板模型进行实证检验。研究结果表明:在时间维度上,中国显著优势、一般优势、潜在优势工业在空间分布上经历了由2000年的错落相间到2017年的高度集中并呈现由核心区域向周边区域扩散的趋势;在空间维度上,工业集聚具有明显的空间相关性且市域间存在显著的空间溢出效应;工业集聚具有多源性,比较优势战略、新经济地理和经济政策等因素均是市域工业集聚的形成原因,各影响因素存在直接效应与间接效应,工业集聚易受到周边地区经济发展的影响。

Economic agglomeration has become a universal feature of economic growth at present stage,and it plays an important role in the development of China’s regional and urban economy.First of all,this paper,based on the panel data of China’s cities,reveals the spatial effect of industrial agglomeration in China’s cities.Secondly,this paper establishes the empirical analysis framework of comparative advantage strategy,new economic geography,economic policy factors and industrial agglomeration,and uses the dynamic spatial panel model for empirical test.There are following empirical results:(1)In the time dimension,China has significant advantage,general advantage and potential advantage.In terms of spatial distribution,the industries experience a high concentration from 2000 to 2017,and show a trend of spreading from the core area to the surrounding areas.(2)In the spatial dimension,industrial agglomeration has obvious spatial correlation,and there is significant spatial spillover effect among cities.(3)The influencing factors of industrial agglomeration are multiple sources.The factors of comparative advantage strategy,new economic geography and economic policy are the reasons for the forming of industrial agglomeration.At the same time,there are direct and indirect effects among the influencing factors,that is,industrial agglomeration is easily affected by perip heral economic development.
