The Influence Of Social Network Relationship On Family Medical Expenditure In Our Country

With the improvement of living standards of Chinese residents,medical and health expenses have been increasing,but the personal medical expenses have been reduced.China ranked 145 th in the world in terms of the percentage of medical and health expenditure in GDP in 2017.Therefore,it can be found that China's per capita medical expenditure is relatively low.With the increase of national medical subsidy and per capita disposable income of residents,the allocation of family medical expenditure has also changed.The composition of medical expenditure has gradually changed from passive medical expenditure in emergency response to diseases to active medical expenditure in combination with disease response and disease prevention.As a country with a traditional emphasis on "relationship" and "human relationship",social network relationship is bound to affect family medical expenditure.How social networks affect family medical expenditure will be the focus of this paper.This paper uses the data of Chinese family dynamic tracking survey(CFPS2014)to explore the influence of social network relationship on Chinese family medical expenditure.Firstly,Tobit basic regression method was used to study the influence of social network on medical expenditure.Secondly,the robustness test of the influence of social network relationship on medical expenditure was studied,including the overall robustness test and the robustness test of control variables.The propensity score matching method was used to verify the influence of social network relationship on medical expenditure and eliminate the selective bias of the benchmark Tobit regression model.Finally,we discuss the group heterogeneity of the influence of social network on medical expenditure.The propensity score matching(PSM)method was used here,and it was found that the influence of social network relationships on medical attitudes was different among different groups.The research shows that:(1)social network relationship can help to reduce family medical expenditure.By reducing the information asymmetry of residents' families,the social network relationship can obtain more medical and health information to reduce the family medical expenditure.Relatives and neighbors help to reduce familymedical expenditure,and social relations help to improve family medical expenditure.In the process of building new China,the government should strengthen the construction of a harmonious society and promote the establishment of a good social network among the residents.(2)according to the subgroup study,the medical expenditure of the insured,hospitalized and high-education families was significantly higher than that of the uninsured,non-hospitalized and low-education families.In addition,families with high economic capital,high health level,high exercise frequency,married families,large family size,and high average age all have higher medical expenditure than those with low economic capital,low health level,low exercise frequency,unmarried families,small family size,and low average age.(3)urban-rural segmentation,regional differences and differences in medical level are still important sources of differences in medical expenditure.From a regional perspective,the eastern region has a higher medical expenditure than the central and western regions,followed by the central region and the western region.The higher the medical level in the community,the higher the medical expenditure.With the advance of urbanization,the difference between urban and rural areas is smaller and smaller,but the medical expenditure of urban families is still significantly higher than that of rural families.
