摘要
基于2011—2020年中国82个涉农企业面板数据,根据所属地理位置,将其分为东部、中部、西部地区,运用超额对数生产函数对农业生产率进行测算,在此基础上测算要素配置效率,并对各地区要素配置效率对农业生产率的影响进行实证考察。结果表明:要素投入的持续增加不能带来产出的持续增加,结合要素之间的组合作用说明要素的投入存在最佳投入范围。东部、中部地区涉农企业的资本要素对产出的影响分别呈现出显著的U型和倒U型特征,劳动要素对产出的影响呈现显著的倒U和负向作用,并且存在组合效应,西部地区不存在显著曲线特征;东、中、西部地区资本和劳动要素对产出都存在显著的线性作用和组合效用,且线性作用均为正向作用,组合效用为负向作用;东、中、西部地区的资本配置效率对农业生产率具有阻碍作用,其中中部地区最强,西部次之,东部最弱;东部、中部地区的劳动要素配置效率对农业生产率起促进作用,但西部地区则是抑制作用;整体来看,资本要素配置效率绝对值均大于劳动要素配置效率。为此,企业需提升要素配置效率,减少要素配置扭曲,以此提升农业生产率。
Based on the panel data of 82 agriculture-related enterprises in China from 2011 to 2020,this paper divided these enterprises into eastern,central and western regions according to their geographical location,and used the excess logarithm function to measure agricultural productivity.On this basis,the efficiency of factor allocation was calculated,and the influence of factor allocation efficiency on agricultural productivity in each region was investigated empirically.The results show that the continuous increase of factor input can’t bring about the continuous increase of output.Combined with the combination of factors,it shows that there is an optimal range of factor input.The influence of capital elements on output of agriculture-related enterprises in the eastern and central regions presents significant U-shaped and inverted U-shaped characteristics respectively,and the influence of labor elements on output presents significant inverted U-shaped and negative effects,with a combined effect.There is no significant curve characteristic in the western region.Capital and labor factors in the eastern,central and western regions have significant linear and combined effects on output,and the linear effects are positive,while the combined effects are negative.The efficiency of capital allocation in the eastern,central and western regions hinders agricultural productivity,among which the central region is the strongest,followed by the western region,and the eastern region is the weakest.The allocation efficiency of labor factors in the eastern and central regions promotes agricultural productivity,but that of the western region inhibits it.On the whole,the absolute value of capital factor allocation efficiency is greater than the efficiency of labor factor allocation.Therefore,enterprises need to improve the efficiency of factor allocation and reduce the distortion of factor allocation,so as to improve agricultural productivity.
