摘　　要：基于2018年京津冀蔬菜种植户调查数据,采用OLS、QR与3SLS法分析了信息化影响农民增收的信息要素差异与个人禀赋差异。研究结果表明,就整体而言,信息基础投入有增收效应,信息技术采纳没有增收效应,且二者没有交互作用。就不同收入阶层农户而言,信息基础投入与信息技术采纳对高农业收入农户均有增收效应,但二者存在替代效应;信息基础投入对低农业收入农户没有增收效应,信息技术采纳则有减收效应,但二者存在互补效应。相较于物质资本或人力资本匮乏的农户,物质资本或人力资本丰富的农户信息基础投入与信息技术采纳的增收效应更为明显。Based on the survey data of vegetable growers in Beijing,Tianjin and Hebei in 2018,this paper uses OLS,QR and 3 SLS to analyze the impact of informatization on farmers’income in different information elements and personal endowment.The results show that as a whole,the information infrastructure input has an Income-increasing effect,the information technology adoption has no Income-increasing effect,and the two have no interaction.But for different income classes,the information infrastructure input and information technology adoption have an Income-increasing effect but a substitution relationship in high income class,while the information infrastructure input and information technology adoption have no Income-increasing effect or Income-decreasing effect respectively but a complementary relationship in low income class.Further,compared with the farmers lacking in material capital or human capital,the information infrastructure input and information technology adoption have more obvious Income-increasing effect on the farmers rich in material capital or human capital.
