互联网使用对居民幸福感的影响——来自CSS2013的经验证据

The Impact of Internet Use on the Subjective Well-being of Residents: Evidence from CSS2013

基于2013年度中国社会状况综合调查数据(CSS2013),本文系统考察了互联网使用对居民主观幸福感的影响。实证结果表明,使用互联网会显著提升居民的主观幸福感,在加入其他控制变量、考虑地区异质性后,这一效应依然存在。为了克服互联网使用的潜在内生性问题,本文以居民2012年通讯支出为工具变量,运用双变量有序Probit模型(Bioprobit模型)和工具变量条件混合过程估计法(CMP方法)进行回归,并进一步使用倾向得分匹配法构造反事实框架纠正选择性偏误,结论依然支持互联网使用对居民主观幸福感的正向效应。分样本估计结果还显示,农村居民使用互联网获得的"幸福效应"要明显强于城镇居民,同时,中西部地区居民使用互联网获得的幸福感要显著强于东部地区。

Based on the survey data of China＇ s social situation in 2013 （CSS2013）, this paper systematically investigates the impact of Internet use on the subjective well-being of residents. The empirical results show that the use of the Internet will significantly enhance the subjective well- being of residents. After adding other control variables and taking into account the heterogeneity of the region, this effect still exists. In order to overcome the potential endogeneity problem, residents＇ communication expenditures in 2012 are used as instrumental variable, using the bivariate ordered probit model （Bioprobit model） and instrumental variable conditions of mixing process regression estimation method （CMP method）, and further using the propensity score matching approach to construct the counterfactual framework and to eliminate selection bias, the conclusion still holds for the positive impact of internet use on the subjective well- being of residents. The results of sub sample also show that the ＂happiness＂ effect generated by the rural residents using the Internet is much stronger than that of the urban residents. At the same time, the ＂happiness＂ effect on residents in the central and western regions is significantly stronger than that in the eastern region.
