互联网使用促进农户创业增益了吗？——基于内生转换回归模型的实证分析

本文从互联网采购和互联网销售参与两个方面表征互联网使用,依据陕西、宁夏和山东831户创业农户调查数据,运用内生转换回归(ESR)模型,探究了互联网使用对农户创业绩效水平的影响效应,并采用Fields分解法检验了互联网使用对农户创业绩效差距的作用方向及程度。研究结果表明,农户参与互联网采购和互联网销售均显著提升了其创业绩效。基于反事实假设,参与互联网采购和互联网销售农户若未使用互联网采购及互联网销售,其创业绩效分别下降12.79%和4.54%;未参与互联网采购和互联网销售农户若使用互联网采购和互联网销售,其创业绩效分别提升44.15%和14.19%,即参与互联网采购对农户创业绩效水平的正向影响大于参与互联网销售的正向作用。研究进一步证实,互联网使用扩大了农户创业绩效差距,参与互联网采购和互联网销售对农户创业绩效差距的贡献率分别为5.51%和3.94%,即参与互联网采购对农户创业绩效差距的贡献率大于参与互联网销售的贡献率。

Does Internet Use Improve Rural Households’ Entrepreneurial Performance? An Empirical Analysis Based on Endogenous Switching Regression Model

Using the survey data collected from 831 entrepreneurial households in Shaanxi,Ningxia and Shandong Provinces,this article employs an endogenous switching regression model to explore the impact of Internet use on rural households’entrepreneurial performance.The study characterizes Internet use in terms of participation in Internet purchase and Internet sales,and uses the fields decomposition method to test the impact direction and degree of Internet use on the entrepreneurial performance gap.The results show that participation in Internet purchase and Internet sales significantly improve rural households’entrepreneurial performance.Based on counterfactual assumptions,if farm households who took part in Internet purchase or Internet sales did not use Internet purchase or Internet sales,their entrepreneurial performance would decrease by 12.79%and 4.54%,respectively,and if farm households who did not take part in Internet purchase or Internet sales did use Internet purchase or Internet sales,their entrepreneurial performance would increase by 44.15%and 14.19%,respectively.The results indicate that the positive impact of participating in Internet purchase on the level of farmers’entrepreneurial performance is greater than that of participating in Internet sales.The study also confirms that Internet use has widened the entrepreneurial performance gap of rural households.Among them,the contribution rates of participating in Internet purchase and Internet sales to the entrepreneurial performance gap are 5.51%and 3.94%,respectively,that is,the contribution rate of participating in Internet purchase to the performance gap is greater than that of Internet sales.
