交易效率、福利增进与城市化

Transaction Efficiency,Welfare Enhancing and Urbanization

城市化的本质,是基于交易效率提升的消费者福利增进。通过对城市化性质的分析,确定了城市化的研究应建立导向交易效率的一般均衡分析框架,并以福利增进为目标,引入二元结构系数、法律环境完善系数和社会生活能力系数来完善城市化一般均衡分析模型。经过假设、建立决策方程、求解,得出当农产品消费比重低于50%时,交易效率对城市化水平的提高起正向作用,另外,社会生活能力系数、二元结构系数提高对城市化提高均起正向作用,法律环境完善系数对城市化的作用未知,但从居民因城市化而取得的利益(或效用)来看,法律完善系数显然将显著影响其大小。

The nature of urbanization is enhancing consumer＇s welfare based on higher transaction efficiency. Through the analysis of the nature of urbanization, aiming at the welfare enhancement, a transaction efficiency-oriented general equilibrium framework is established by introducing coefficients of dual structure, perfect legal environment and social living ability. By solving the decision equation based on assumptions, transaction efficiency, as well as social living ability coefficient and the dual structure coefficient, will play a positive role in improving the level of urbanization when agricultural products consumption ratio is below 50%. Different from these factors, influence of perfect legal environment coefficient is uncertain.
