专业化分工视角下城市间分享经济:定义、形成机制与政策含义

从新兴古典经济学的视角研究城市间分享经济的微观机制。研究得出:（1）城市间分享经济来源于对方城市中个人在生产产品时的专业化经济，且随着专业化经济程度的提高而增加。（2）城市间分享经济的产生需要城市间进行分工，而城市间分工的形成必须要求城市间交易成本系数减小到一定的临界值。（3）城市间分享经济的增加可使城市间分工所要求的城市间交易成本系数减小幅度更小。在此基础上考察了中国城市的发展，并总结出具有参考价值的政策含义。

Sharing Economy between Cities from the Perspective of Specialized Division of Labor: Definition,Formation Mechanism and Policy

This paper studies the micro mechanism of sharing economy between cities from the perspective of new classical economics.The results show that:(1)the sharing economy between cities comes from economies of specialization of the individual in the production of the products in the other cities,and increases with the improvement of The degree of economies of specialization;(2)The emergence of sharing economy between cities requires the division of labor between cities,and the formation of inter-city division of labor requires that the inter-city transaction cost coefficient be reduced to a certain threshold;(3)The increase of sharing economy between cities can make the inter-city transaction cost coefficient required by inter-city division of labor bigger.
