现代通讯技术使用对农户要素投入的影响——基于山东省寿光蔬菜种植户的分析

Impact of the Use of Modern Communication Technology on Farmers’Factor Input——Based on Evidence From Vegetable Growers in Shouguang of Shandong Province

以山东省寿光754个蔬菜种植户为样本,利用倾向得分匹配法和逐步回归分析法检验现代通讯技术使用对要素投入的影响效应及作用机制。研究表明:(1)现代通讯技术使用有助于增加总物质资本、种苗和机械投入,降低农膜、农药和化肥投入,从而有利于农业要素结构的优化和生产方式的转变。(2)使用现代通讯技术农户的物质资本投入与人力资本投入存在负相关,而与土地投入存在正相关。现代通讯技术的使用对增加大规模农户的机械投入,减少小规模农户的农膜、农药投入影响较大,这有利于推动农业现代化进程,实现小农户与大市场的对接。(3)现代通讯技术使用能够通过科技进步、市场参与和社会网络的路径影响农户的要素投入,中介效应占总效应的比重分别是9.37%、11.22%和15.54%。据此,建议重视现代通讯技术发展,鼓励规模化经营,进一步把推动科技进步、增强市场参与及拓展社会网络协同并进。

Based on the theory of modern communication technology use on factor input and taking 754 vegetable growers in Shouguang of Shandong Province as samples,this paper uses the propensity score matching method and stepwise regression analysis method to test the effect and mechanism of modern communication technology use on factor input.The research shows that:First,the use of modern communication technology helps increase the total physical capital,seedlings and machinery input,and reduces the input of agricultural film,pesticides and fertilizers,which is conducive to the optimization of agricultural factor structure and the transformation of production methods.Second,the physical capital investment of farmers who use modern communication technology is negatively correlated with human capital investment,and there is a positive correlation with land investment.In addition,the use of modern communication technology has a greater impact on increasing the machinery input of large-scale farmers and reducing the input of agricultural films and pesticides for small-scale farmers.This is conducive to promoting the process of agricultural modernization and realizing the connection between small farmers and the big market.Third,the use of modern communication technology can influence the input of farmers through technological progress,market participation,and social network.The proportion of intermediary effects in the total effect is 9.37%,11.22%,and 15.54%,respectively.Based on this,suggestions are put forward as follows:to attach importance to the development of modern communication technology,encourage large-scale operation,and further advance the promotion of scientific and technological progress,enhance market participation,and expand social networks.
