Research On Measurement Of Household Consumption Inequality Based On Regional And Community Perspectives

Under the development situation that the new normal economy is driven by investment to consumption,China's average consumption level shows a relatively fast growth trend.Consumption upgrading improves people's lives as a whole and enhances social welfare,but at the same time of consumption upgrade,China's large income gap,the imbalance of different social stratum structure,will increase household consumption inequality,weaken the generality of consumption upgrading,resulting in consumption polarization,structuralization and other obvious consumption stratification,leading to consumption upgrades into development Dilemma.Therefore,measuring the inequality of household consumption and deeply analyzing the causes of consumption inequality have very important practical significance for policy makers.In the past consumption inequality measures,only a small number of domestic scholars used the Zenga index.Considering the excellent nature of the Zenga index and its comparability with other studies,the Gini coefficient and the Zenga index were used in combination,and the micro survey data of the Chinese family tracking survey(CFPS)on 2010-2016 was adopted.Measuring the degree of household inequality and trends in China,and through the Gini coefficient and the Zenga index sub-item decomposition method to study the contribution of household sub-items to total consumption inequality.Further,the stratified model is used to analyze the main factors affecting the family consumption inequality in the community level from the macro-level level and the middle-level community level.Then,based on the differences in consumption of different social classes,the Gini coefficient sub-group decomposition method is used to measure the intra-group And the contribution rate of the difference between groups to the total consumption inequality,analyze the social structural factors that cause the inequality of household consumption to become more prominent.Based on the above research,the following conclusions are obtained: 1.The phenomenon of consumption inequality is more and more prominent.Although the per capita consumption level of households in China is continuously increasing,the overall consumption difference is also growing.2.From the perspective of consumption structure,there is a significant difference in the trend of change in the level of consumer inequality and the relative contribution rate and marginal contribution rate.Food,clothing,health care,cultural and educational entertainment expenditures and other consumer expenditures are inequitable to total consumption.Inhibition,increased consumption will improve inequality,and other sub-sectors have opposite effects on total consumption inequality.3.The level of regional economic development has the greatest impact on household consumption inequality in the region,and has a reverse impact,that is,the higher the level of economic development,the lower the level of consumption inequality,but in reality the degree of inequality in household consumption is increasing with economic development.The higher,the further analysis shows that the consumption stratification of different social strata has caused household consumption inequality to intensify.The research results provide some reference suggestions for policy formulation.In the policy formulation,the basic consumption of residents and the consumption in key areas of people's livelihood should be guaranteed,and the multi-level and diversified consumer demand of different groups should be satisfied,and a new growth point with strong driving force should be formed to solve the society.Structural imbalances,optimizing the path of consumption upgrades.
