摘要
Marshall外部性是产业集聚影响生产率的方式之一,由于资源禀赋、组织形式和政策环境等产业特殊性,农业集聚对产业生产率的影响具有异质性。基于DEA-Manquist指数,测算2002—2016年中国31个省级行政单位的农业全要素生产率(TFP),并运用面板门槛模型分析了农业集聚对农业TFP的非线性影响。研究表明,农业集聚对全要素生产率的影响具有显著的门槛效应,随着农业集聚度的提高,出现阶梯递减现象。当集聚度小于等于0.94时,每增加1个单位,带动农业全要素生产率增加0.709个单位,当集聚度大于等于0.94时,将带动全要素生产率增加0.437个单位。同时,农业集聚对农业TFP的影响具有区域异质性,东部地区农业集聚与全要素生产率之间呈现出“V”型结构,中西部地区两者则呈现出“L”型结构。
The existence of spatial externalities is an important reason for the formation of industrial agglomeration.However,the role of agricultural agglomeration for economic development is more complicated due to the particularities of industries such as resource endowment,organizational forms,and policy environment.In this paper,the DEA-Manquist was used to calculate agricultural total factor productivity(TFP)in 31 provinces in China from 2002 to 2016,and a panel threshold model was used to analyze the nonlinear impact of agricultural agglomeration on agricultural TFP.Research shows that the marginal effect of agricultural agglomeration has a significant threshold effect.As the degree of agricultural agglomeration increases,a step-down phenomenon occurs.Agricultural agglomeration significantly improved agricultural TFP.When the agglomeration degree is less than or equal to 0.94,each additional unit will increase the total agricultural productivity by 0.709 units.When the agglomeration degree is greater than or equal to 0.94,it will increase the total factor productivity by 0.437 units.At the same time,the impact of agricultural agglomeration on agricultural TFP has regional heterogeneity.Agricultural agglomeration and total factor productivity in the eastern region show a"V"shape,while the central and western regions show a"L"shape.
