摘要:

目的 为推进农用化学品减量投入，实现中国农业绿色发展，分析农地规模、社会化服务对农用化学品投入的减量机制，进而探究农地规模对社会化服务的助推作用以及社会化服务在农地规模与农用化学品减量投入之间如何发挥中介作用。方法 文章基于2020年“黄河流域生态保护与农业农村高质量发展”专项调研数据，依照经营规模大小将农地规模分为不同等级，构建结构方程模型进行实证分析。结果 （1）农地规模对农用化学品投入的减量作用仅在农地规模处于中等水平时显著；（2）社会化服务对农用化学品投入的减量作用在整个农地规模发展进程中都显著；（3）农地规模对社会化服务的促进作用在农地规模处于低中等水平时显著；（4）社会化服务在农地规模与农用化学品减量投入之间的中介作用在农地规模处于中等水平时显著。结论 因此，应大力推广适度的农地规模，同时发展社会化服务，以推动中国农业绿色发展。

Abstract:

In order to push the reduction of inputs of agricultural chemicals and realize the green development of agriculture in China, it is a solution to analyze the reduction mechanism of farmland scale and socialized services on agricultural chemical inputs, so that the promotion of farmland scale on socialized services and its intermediary effect can be further explored. Based on the special research data of “Ecological Protection and High-Quality Development of Agriculture and Rural Areas in the Yellow River Basin” in 2020, farmland scale was divided into different levels according to operation scale, and a structural equation model was constructed to make an empirical analysis. The results were showed as follows. (1) Only when the farmland scale was at the medium level would the reduction effect of farmland scale on agricultural chemical inputs be significant. (2) Throughout the development of farmland scale, socialized services had an evident effect on reduction inputs of agricultural chemicals. (3) The promotion function of farmland scale on socialized services was obvious when the farmland scale was at a low and medium level. (4) At a medium level, socialized services could play a partially intermediary effect between farmland scale and reduction inputs of agricultural chemicals. Therefore, it is necessary to develop a moderate farmland scale and socialized services to promote the reduction inputs of agricultural chemicals as well as the green development of agriculture.
