The dynamic impact of income and income distribution on food consumption among adults in rural China

Previous studies have demonstrated that income has a significant effect on food demand in rural China. However, little research has focused on the dynamic impact of income and income distribution on food demand in rural China. Using China Health and Nutrition Survey data, this study employs a consistent two-step quadratic almost ideal demand system model, with addressed problems of endogeneity of total expenditure and zero shares, to estimate the food demand elasticities among adults in rural areas with regard to the different income strata. The results show that changes in income and income strata have significant effects on food demand in rural areas. Except for grains, all other food groups, including vegetables, oils and fats, animal products, and other foods, have positive income elasticities, and the rise in the income strata will lead to declining income elasticities for grains, vegetables, oils and fats, and animal products. Based on the estimated income elasticities, the food consumption projections indicate that reducing income inequality in rural society can improve the living standard of low-income people in terms of nutrient intakes.

Intra-family Income Redistribution and Its Dynamic Changes among the Elderly in China:2002-2018

This paper studies the impact of household income redistribution on income inequality among the elderly from 2002 to 2018. It defines shared income and measures how each family member's contributions affect income inequality among the elderly. The study has three major findings. First, from 2013 to 2018, the role of household shared income in reducing income inequality among the elderly increased. Second, the proportion of shared income contributed by children was the highest overall, reaching 11.0 percent nationwide and even 17.9 percent in rural areas in 2018. The contribution of shared income to inequality was also higher among the rural elderly. Grandchildren under 16 largely received shared income from the elderly, and the income transferred by the male elderly to their wives was obvious. Third, changes in family structure narrowed the inequality gap among the elderly in the periods 2002–2013 and 2013–2018.

A Study on the Income Redistribution Effect of China’s 2018 Personal Income Tax Reform

Personal income tax is an important redistribution tool,its redistribution effect has been concerned by all walks of life.Using CHIP2018,this paper calculates and analyzes the income redistribution effect of the personal income tax reform plan in 2018,and fi nds that:The comprehensive taxation can raise the average tax rate,progressivity and redistribution effect of personal income tax;The rise of the standard of basic deduction,six special additional deductions,and the change of tax rate structure raise the progressiveness of personal income tax,but reduce the average tax rate and thus weaken the income redistribution effect of personal income tax;The comprehensive income tax will enhance the impact of basic deduction of expenses,six special additional deductions and the change of tax rate structure on the redistribution effect of individual income tax income;Under the joint action of the reform measures,the progressivity of individual income tax has risen as a whole,but the average tax rate of individual income tax and redistribution index have shown a sharp decline,both of which decreased by more than 50%.Using the household survey data of the year of reform,this paper comprehensively investigates the income redistribution effect of the personal income tax reform,which enriches the research on the redistribution effect of the new round of personal income tax reform.
