农地流转背景下地块规模对农户种粮投入影响分析
Impact of plot size on farmers' grain investments under the background of farmland transfer
摘要
Abstract
In recent years,national food security is gaining extensive attention of China.As an important factor of grain production,farmland investments are the premise of stable grain output.Scholars have made lots of efforts to study about the influence of plot size on farmers' grain investments.However,due to farmland transfer,land factors become more diversified,which results in changes of the relationship between plot size and farmers' grain investments.With the rapid development of farmland transfer in China,it is urgent to analyze the influence of plot size on farmers' grain investments under the impact of farmland transfer,which is of great significance to ensure the national food security.Considering the heterogeneity of different plots,this paper makes a multi-level regression analysis from levels of villages and farmers based on the grain production data in 1 284 plots owned by 622 farmers in three major grain production provinces of Shandong,Henan and Anhui,with production material price,plot factor and other non-subjective factors conerolled.Result shows that farmland transfer characteristics and field characteristics have a significant influence on farmer's grain investments per unit area.The coefficients of plot size and transfer proportion are both negative.With the enlargement of farmer's land transfer scale,their opportunity cost for pursuing land production increases,which can give them more motivation to inerease grain investments,and then coefficient of plot size on grain investment becomes smaller.Three conclusions are drawn from empirical results.In the first place,scale operation can help decrease the grain input cost per unit area;secondly,when farmland transfer happens,the influence of plot size on grain investment changes and large scale operation will become an inevitable trend in China;thirdly,plots with good conditions can improve farmer's grain production enthusiasm and decrease input cost.To ensure the national food security,the government needs to take measures to decrease grain input cost and increase the revenue.It is suggested to encourage farmland transfer and promote grain large-scale production.Meanwhile,the government needs to increase the financial allocation to construct high standard grain field with more infrastructure and supporting engineer.关键词
