参与电商会促进猕猴桃种植户绿色生产技术采纳吗?——基于倾向得分匹配的反事实估计

本文利用陕西、四川两省686户猕猴桃种植户的调查数据,在采用变异系数法度量猕猴桃种植户绿色生产技术采纳程度的基础上,利用倾向得分匹配法构建反事实框架,实证分析参与电商对猕猴桃种植户绿色生产技术采纳的影响效应。结果表明:猕猴桃种植户绿色生产子技术的重要性依次为测土配方施肥技术、物理防治技术、套袋技术、无公害农药使用技术、有机肥施用技术;在控制样本选择偏差后,参与电商对猕猴桃种植户绿色生产技术采纳有显著的正向影响;参与电商对不同资本禀赋的猕猴桃种植户绿色生产技术采纳的促进效应存在差异;参与电商通过提升产品价格预期、提升经济收益水平、提升信息获取能力、追求正向社会评价四条路径来影响猕猴桃种植户的绿色生产技术采纳。

Does Participating in E-commerce Promote the Adoption of Green Production Technologies by Kiwifruit Growers?A Counterfactual Estimation Based on Propensity Score Matching Method

This article uses survey data from 686 kiwifruit growers in Shaanxi and Sichuan Provinces and the coefficient of variation method to measure the adoption degree of green production technologies by kiwifruit growers.It builds a counterfactual framework by using the propensity score matching method and empirically analyzes the effect of participating in E-commerce on the adoption of green production technologies by kiwifruit growers.The results show that the most important green production technology of kiwifruit growers is soil testing and fertilization technology,followed by physical control technology,bagging technology,pollution-free pesticide application technology,and organic fertilizer application technology.After controlling the sample selection bias,participating in E-commerce has a significant positive impact on the adoption of green production technologies by kiwifruit growers.Participating in E-commerce has different promotion effects on the adoption of green production technologies by kiwifruit growers with different capital endowment.Participating in E-commerce influences the adoption of green production technologies by kiwifruit growers via raising product price expectations,increasing economic income levels,improving information acquisition capabilities,and pursuing positive social evaluations.
