专业市场集聚对区域经济增长的空间溢出效应研究

Research on spatial spillover effects of specialized market agglomeration to regional economic growth

专业市场作为一种交易活动的空间集聚现象,在推动区域经济发展过程中发挥了重要的作用。采用2010—2019年中国31个省区的数据,对专业市场的集聚水平进行测度,并分析了专业市场的空间集聚特征;然后运用空间杜宾模型,验证了专业市场集聚对区域经济增长的空间溢出效应。研究结论如下:(1)2010—2019年中国专业市场发展存在显著的空间集聚特性,且表现出一定的自我锁定特征,“强强集聚、弱弱集聚”的格局特征明显;(2)专业市场对区域经济的增长存在显著的正向影响但空间溢出效应不显著,专业市场集聚水平每增加一个百分点,能直接引起本地区经济增长0.06个百分点;(3)劳动力投入、资本投入、对外开放等对经济增长具有正向促进作用,并存在空间溢出效应。

As a spatial agglomeration of trading activities,specialized markets play an important role in promoting regional economic development.This paper used the data of 31 provinces in China from 2010 to 2019 to measure the agglomeration level of specialized markets,and analyzed the spatial agglomeration characteristics of specialized markets.Then,used the spatial Dobin model to verify the spatial spillover effect of specialized market agglomeration on regional economic growth.The research conclusions are as follows:(1)From 2010 to 2019,the specialized market of 31 provinces in China have significant spatial agglomeration characteristics,and show certain self-locking characteristics.The eastern coastal provinces have always shown high agglomeration characteristics,and the western inland provinces have always been in a state of low agglomeration;(2)The specialized markets have a significant positive impact on the growth of the regional economy,but the spatial spillover effect is not significant.Every percentage point increase in the specialized markets agglomeration level can directly lead to 0.06 percentage points of economic growth in the region;(3)Labor input,capital investment,opening to the outside world,etc.have a positive role in promoting economic growth,and there is a spatial spillover effect.
