摘要
文章采用2018年中国家庭追踪调查(CFPS)数据,考察了互联网使用对农村居民体育锻炼的影响,并探讨了该影响在不同群体中可能存在的异质性及其影响机制。研究结果显示,互联网使用显著降低了农村居民体育锻炼的时间及频率,相较于体育锻炼所花费的时间,互联网使用对农村居民体育锻炼频率的抑制作用更加明显。异质性分析表明,相比于年龄在40岁以下、男性、健康状况不佳、没有参加医保的农村居民,互联网使用对年龄在40岁及以上、女性、健康状况良好、参加医保的农村居民体育锻炼的抑制作用更加显著。进一步机制分析发现,互联网使用挤占了农村居民的闲暇时间,从而抑制了居民的体育锻炼行为,表明闲暇时间是互联网使用影响农村居民体育锻炼的重要机制。上述结果在运用倾向得分匹配(PSM)消除样本选择性偏差后依然保持稳健。
This article uses the 2018 China Family Panel Survey(CFPS)data to investigate the impact of Internet use on physical exercise of rural residents,and explores the possible heterogeneity of the impact among different groups and its impact mechanism.Research results show that Internet use significantly reduces the time and frequency of physical exercise of rural residents.Compared with the time spent on physical exercise,Internet use has a more obvious inhibitory effect on the frequency of physical exercise of rural residents.Heterogeneity analysis shows that compared with rural residents who are under 40 years of age,male,poor health,and not covered by medical insurance,Internet use is more effective for rural residents aged 40 and above,female,with good health,and who are covered by medical insurance.The inhibitory effect of physical exercise is more significant.Further mechanism analysis found that Internet use squeezed the leisure time of rural residents,thereby inhibiting residents’physical exercise behavior,indicating that leisure time is an important mechanism for Internet use to affect rural residents’physical exercise.The above results remain robust even after using propensity score matching(PSM)to eliminate sample selectivity bias.
