摘要
[目的]研究中国粮食生产水土资源配置效率及其影响因素,为保障粮食安全提供理论支持。[方法]结合农地流转对粮食生产水土资源配置效率的作用机制,基于2005—2020年30个省份的面板数据,利用DEA模型测度了粮食生产水土资源配置的综合效率,探究了农地流转对水土资源配置的影响。[结果]从时间序列来看,中国的粮食生产水土资源配置效率大体上呈现波动性上升趋势。从省份来看,其中河南和吉林等省区在研究期间效率值都为1,实现了DEA有效。安徽、甘肃、宁夏3个省份的粮食生产水土资源配置效率的上升趋势在1%的显著性水平下显著。重庆、浙江、青海和广西4个省份的下降趋势明显;基于空间分布分析得出,地区上水土资源配置效率大致呈现:东北地区>东部地区>中部地区>西部地区。其中河南和吉林省的水土资源配置效率最高,青海省最低。[结论]Tobit回归结果表明农地流转对粮食生产水土资源配置效率有显著影响,并且是有利于提高水土资源配置效率的。
[Objective]The objective of this study was to determine the efficiency of land and water resource allocation in grain production of China and its influencing factors in order to provide theoretical support for ensuring food security.[Methods]Using the DEA model,taking 30 provinces(cities)as samples from 2005 to 2020,an empirical analysis of land and water resource allocation of Chinese grain production was carried out and analyzed.[Results]In the time series,the allocation efficiency of land and water resources showed a fluctuating growth.From the perspective of provinces and cities,the economic utility coefficients of Henan and Jilin Province were both 1,and DEA had a good effect.In the grain production of Anhui,Gansu,and Ningxia,the efficiency of land and water resource allocation was significantly improved by 1%.The four provinces of Chongqing,Zhejiang,Qinghai,and Guangxi all showed significant declines;In terms of spatial distribution,the distribution efficiency of land and water resources in this area was as follows:Northeast,East China,Central China,West China.Among them,Henan and Jilin had the highest soil resource utilization efficiency,and Qinghai had the lowest soil utilization efficiency.[Conclusion]The Tobit regression results indicated that agricultural land transfer significantly affected the efficiency of land and water resource allocation in grain production and is conducive to improving resource allocation efficiency.
