Population Structure,Income Inequality And Credit Expansion

In recent years,the aging of the population is becoming more and more serious.Each country is suffering different degrees of population structure transformation;with the continuous improvement of people’s income and living standards,the social and economic problems caused by income inequality have been paid more and more attention.Therefore,many scholars have done a lot of research on population structure and income inequality.However,owing to the global economic downturn and the unprecedented growth of major currency liquidity,problems brought about by credit expansion are not discussed with the population structure and income inequality.For this reason,this paper used the transnational panel data of 148 countries from1980 to 2017(data from WDI and UNU-WIDER)to analyze the long-term relationship between population structure,income inequality and credit expansion.The relationship between these three factors were deeply elucidated from the point related to the developed countries and developing countries,and finally we constructed a econometric model for empirical test and results analysis,and got the following conclusions:(1)the long-term relationship between population structure and credit expansion has certain heterogeneity.The elderly dependency ratio of population structure in developing countries has a long-term positive relationship with credit expansion,while the elderly dependency ratio of population structure in developed countries has a long-term negative relationship with credit expansion,In both developed and developing countries,the child dependency ratio of population structure has a long-term negative relationship with credit expansion;(2)In both developed and developing countries,there is a long-term positive relationship between income inequality and credit expansion,and the positive relationship between income inequality and credit expansion is more significant in developed countries than in developing countries..
