摘要
本文运用双固定效应SDM模型及其空间溢出效应分解方法,在构建关于集聚效应的新经济地理学模型的基础上,着重对市场潜能、城镇化与集聚效应的关系和作用机制进行了分析。研究表明:市场潜能对地区集聚经济的影响显著为正,并且邻近区域存在竞争的特点。通过城镇化的空间溢出效应分解可以看出,三种城镇化因素对集聚效应的发展有正向影响,但是作用机制各不相同,其中,人口城镇化和经济城镇化只通过直接效应对本地区集聚效应产生正向作用,而土地城镇化通过三种效应对本地区和周围地区产生正向的促进作用。最后,在实证的基础上,本文提出了相应的政策建议。
By using SDM model with spatial and time- period fixed effects and decomposition of spatial spillovers,this paper analyzes the relationship and mechanism of action effects between market potential,urbanization and agglomeration based on a new economic geography model about agglomeration economies. The result shows that market potential and urbanization promote agglomeration economies,and competition from neighboring regions exists. Through decomposition of spillover effects of urbanization,we find that the three factors of urbanization have a positive impact on the development of agglomeration,but their mechanism is different. Specifically,population urbanization and economic urbanization have a positive role in agglomeration economies only through direct effects. Furthermore,land urbanization facilitates the area itself and its surrounding areas by the three effects.Finally,on the basis of empirical results,some related policy recommendations are put forward.
