结构型社会资本对城市群专业化分工的影响研究——基于比较优势理论分析的视角

Research on the Influence of Structural Social Capital on the Specialization of Urban Agglomeration——From the Perspective of Comparative Advantage Theory

比较优势是地区专业化分工的理论依据,但其作用的发挥受制于交易成本的影响。作为非正式制度的重要内容,结构型社会资本是否可以通过降低城市群内部交易成本,对城市群专业化分工产生影响?本文在理论分析的基础上,利用中国2004—2018年十五大城市群的相关数据,采用双向固定效应模型考察了结构型社会资本对城市群专业化分工的影响。研究发现,结构型社会资本对城市群专业化分工具有明显的促进作用;交易成本在结构型社会资本与城市群专业化分工之间发挥了部分中介效应;结构型社会资本在多中心、同省、非国家级以及中西部地区城市群中的作用更显著;同时结构型社会资本的分工效应存在门槛效应,当城市群经济规模和人口规模分别小于33445.981亿元和7814.599万人时,结构型社会资本可以发挥显著的促进作用。

Comparative advantage is the theoretical basis of regional specialization division of labor, but its function is influenced by regional transaction costs.As an important part of informal system, can structural social capital affect the specialization of urban agglomeration by reducing the internal transaction cost of urban agglomeration?Based on the theoretical analysis, this paper uses the relevant data of China’s 15 major urban agglomerations from 2004 to 2018,and uses the two-way fixed effect model to investigate the impact of structural social capital on the specialization of urban agglomeration.It is found that structural social capital has a significant role in promoting the specialization of urban agglomeration.Transaction costs play an intermediary role between the structural social capital and the specialization of urban agglomeration.Structural social capital has a more significant role in multi-center, same-provincial, non-state-level and central and western urban agglomerations.At the same time, there is threshold effect in the division effect of structural social capital.When the economic scale and population size of urban agglomeration are less than 3344.598 billion yuan and 78.1459 million people respectively, the structural social capital can play a significant role in promoting.
