The Effect of Internet Diffusion on Income Inequality: Cross-Regional Analysis in Indonesia

This research tests three hypotheses: 1) Internet diffusion has a significant effect on within-province income inequality in Indonesia; 2) Internet diffusion has a significant nonlinear effect on within-province income inequality in Indonesia; and 3) Internet diffusion has a significant effect on within-province income inequality in Indonesia differing by per capita income and education level. An important finding in this research is that Internet diffusion has a significant effect on income inequality as indicated by the positive influence of the Internet on income inequality between regions. In addition, the influence of the internet tends to be nonlinear and interacts differently with the heterogeneity of each province. The attached data is in .dta and .do format which can be processed with STATA by running the file. Original data was collected from the Badan Pusat Statistik (BPS) website which was processed into STATA. IneqPaper14.dta is a data set and Paper_2013-2019.do contains commands for processing data set files. IneqPaper15_2013-2019.dta is the final processed data.本研究验证了三项假设：1）互联网普及对印度尼西亚省内收入不平等具有显著影响；2）互联网普及对印度尼西亚省内收入不平等具有显著的非线性影响；3）互联网普及对印度尼西亚省内收入不平等的影响因人均收入与教育水平而异。本研究的一项重要发现为，互联网对区域间收入不平等的正向影响表明，互联网普及对收入不平等具有显著作用。此外，互联网的影响往往呈现非线性特征，且与各省份的异质性产生差异化交互效应。随附的数据格式为.dta与.do，可通过STATA运行对应文件进行处理。原始数据采集自印度尼西亚中央统计局（Badan Pusat Statistik, BPS）官网，经处理后适配STATA格式。其中IneqPaper14.dta为数据集文件，Paper_2013-2019.do包含数据集的处理命令，IneqPaper15_2013-2019.dta为最终处理完成的数据集。
