农业高质量发展视域下的农地流转、产权归属与地块生产率

Farmland Circulation,Property Right and Land Productivity from the Perspective of High-quality Agricultural Development

明晰产权与提高土地生产率有利于在农业高质量发展进程中保障国家粮食安全。采用2017-2018年两轮地块兼农户调查数据,应用多元回归与工具变量法,对农地流转、产权归属对土地生产率的影响进行了实证分析。研究发现:流转农地可以提高地块生产率:提升幅度在2.4%-3.2%之间;地块面积与生产率之间存在着倒U型关系,意味着地块样本中存在反向关系;不同产权归属的土地生产率呈现出了显著的差异,自有承包地的土地生产率高于转入地块。

Improving land productivity is conducive to ensuring national food security,in the process of promoting high-quality agricultural development,in China.Based on two rounds of land plot survey data from 2017 to 2018 and multiple regression and instrumental variable method,this paper empirically analyzed the impact of farmland transfer and property right ownership on the land plot productivity.The results are as follows:transferring the agricultural land is conducive to improving the land productivity at the plot level:between 2.4%and 3.2%.There is an"inverted U-shaped"relationship between land area and land productivity,and new evidence of the existence of“reverse relationship”is found in land plot samples.The productivity of self contracted land is higher than that of transferred land.
