摘要
随着大量外来资本注入农地流转市场,以农地流转租金不合理上涨为代表的农地过度资本化现象引起广泛关注。为识别农地过度资本化对粮食生产带来的经济风险,引入“度”的视角,将农地资本化对粮食生产效率的促进效应与破坏效应影响置于关联的统一分析框架,并基于2020年中国1146份微观调研数据与272个村域尺度的调查数据,利用门槛回归模型,从全样本与异质性双维度揭示不同程度农地资本化对粮食生产效率影响的差异。研究发现:农地适度资本化有助于提高粮食生产效率,但农地过度资本化将导致粮食生产效率损失。主要原因在于,农地过度资本化导致农地边际扩大成本高于边际产出,抑制粮食规模化生产,对粮食生产效率产生消极影响,尤其位于粮食主产区的生产者对农地过度资本化风险的抵抗力更弱。未来须规范农地资本化市场运作,完善农地资本化的约束机制,防范农地过度资本化风险。
With substantial external capital influx into the farmland transfer market,the phenomenon of farmland over-capitalization,as manifested through irrational surges in land circulation rents,has become increasingly prevalent.The purpose of this study is to explore the effects of farmland capitalization on the efficiency of grain production and to provide scientific support for the operation and management of the farmland market.We introduce the perspective of degree,and put the promotion and destruction effects of farmland capitalization on grain production efficiency into a related and unified analytical framework.Further,based on the survey data of 1,146 micro-plots and 272 villages in 2020,we establish a model for measuring farmland capitalization and introduce a threshold regression model to reveal the differences in the impacts of different degrees of farmland capitalization on grain production efficiency in terms of the full-sample and heterogeneity dimensions.The results show that moderate capitalization of farmland can improve grain production efficiency.However,excessive capitalization of farmland is more likely to inhibit productivity.One important reason is that excessive capitalization of farmland raises the cost of land for grain production,resulting in higher marginal expansion costs than marginal output,which hurts grain production efficiency.Especially,farmers in the main grain-producing regions are less resistant to the risk of over-capitalization of farmland.In the future,the government must regulate the market operation of farmland capitalization,improve the constraint mechanism of farmland capitalization,and prevent the risk of farmland capitalization.
