经济集聚对福建省城市土地产出率的影响研究

Study on the Influence of Economic Agglomeration on Urban Land Output Rate in Fujian Province

随着农村劳动力持续向城市集聚,城市规划用地供给日趋紧张,如何利用有限的土地资源提高福建省城市土地产出率是亟需研究的现实问题.本文把政府干预程度、经济结构和城市用地规模等指标融入生产函数,以此构建土地产出率的理论模型,并采用面板数据模型进行实证检验.实证分析结果表明:劳动力替代效应使得劳动力集聚与资本集聚相比对城市土地产出率的正向影响更强,但是劳动力过度集聚无法提升福建省城市土地产出率;劳动力的收入效应提高城市人力资本水平,进而提升福建省城市土地产出率;劳动力转移、土地供给扩张以及政府干预过度反而降低土地产出率.本文认为促进经济集聚、优化产业结构和合理利用土地等政策都有利于提高福建省城市土地产出率.

As the rural labor force gathers into cities continuously and the supply of urban planning land is becoming increasingly tight.A practical problem how to use limited land resources to improve the urban land output rate in Fujian needs to be studied.In this paper,the degree of government intervention,economic structure and urban land use scale and other indicators are integrated into the production function with which a theoretical analysis model of land output rate is constructed,and the panel data model are used for empirical testing.The empirical analysis shows that labor substitution effect makes labor agglomeration have a stronger positive impact on urban land productivity than capital agglomeration.However,the excessive concentration of labor force cannot improve the urban land productivity in Fujian.The income effect of labor force improves the level of urban human capital,and then improves the urban land output rate of Fujian province.Labor transfer,land supply expansion and excessive government intervention have reduced the land output rate.It is believed that policies such as promoting economic agglomeration,optimizing industrial structure and rational utilization of land are conducive to improving urban land productivity in Fujian.
