Regional Intergenerational Income Mobility And Its Impact On Rural Labor Inflow

Economists often use intergenerational income mobility as a measure of equal opportunity in a country or region.High intergenerational income mobility means that individual income depends more on their own efforts and abilities,and less on family background.Everyone has relatively fair development opportunities,which is an important embodiment of social equity and justice.The study shows that the rural labor force flows into the city to obtain higher wage income,but on this basis,the balance of equal opportunity is also an important factor to consider.The higher a region of intergenerational income mobility,means more opportunities in the region environment for open,reducing the average family background on the negative impact of rural labor force to realize their own potential,to make it have more chance to achieve revenue jumped and class,which has a powerful suction on rural labor flow ability.At this time,intergenerational income mobility is not only a social equity issue,but also affects economic development by changing the economic behavior of micro-subjects.Therefore,it is of great theoretical and practical significance to measure the intergenerational income mobility and explore its external economic impact.For this reason,this paper first discusses the recent development of intergenerational sequence correlation index and traditional intergenerational income elasticity index of the bias problem,use of intergenerational sequence correlation statistical advantage,the index,absolute intergenerational mobility further comparison in different areas,different income levels of intergenerational mobility,and then on the basis of accurate measure area of intergenerational income mobility,This paper focuses on the micro-economic influence of intergenerational income flow on rural labor inflow from two perspectives: the choice of rural labor inflow place and the savings of rural labor inflow place.Finally,based on the conclusion of theoretical analysis and empirical research,feasible policy suggestions are put forward centering on creating a fair opportunity environment,reasonably guiding rural labor mobility,reducing household savings rate and stimulating economic domestic demand.The main conclusions of this paper are as follows:First,compared with the traditional intergenerational income elasticity method,the intergenerational rank correlation method has better linear fitting ability,and is less affected by sample bias of zero and low income,life cycle bias and temporary bias.Based on the statistical advantages of intergenerational rank correlation method,this paper proposes a new measurement method of intergenerational income mobility from the perspective of absolute intergenerational mobility,which supplements and extends the existing measurement method.Second,this paper calculates the intergenerational income mobility of 228 cities,covering 31 provinces(municipalities directly under the Central Government)in China.The national level and city level of intergenerational bit sequence correlation 0.129 0.772,differences of intergenerational income mobility in China is bigger,intergenerational income mobility of high value area are mainly distributed in jiangsu and zhejiang area,low area are mainly distributed in the western region and northeast China,among them,in low-income and middle-income class absolutely the highest city in the intergenerational mobility to hangzhou,Shanghai is the city with the highest absolute intergenerational mobility of middle and high income class.Thirdly,intergenerational income mobility has a significant positive impact on the choice of rural labor destination.Cities with higher intergenerational income mobility are more likely to have rural labor inflows.The rural labor force with different educational background and marital status has heterogeneous reflection on the intergenerational income mobility.The rural labor force with low educational background and children has stronger reflection on the intergenerational income mobility,and the rural labor force with high educational background and no children tend to flock to the place where the average salary of employees is higher.In order to realize the upward mobility of rural labor force,it is the internal mechanism of its flow to the regions with high intergenerational mobility.The higher the level of regional intergenerational mobility,the easier it is to realize the upward mobility of rural labor force.Fourth,the concentration of rural Labour in places with higher intergenerational income mobility is one of the reasons why households save more in the places of their inflow.On average,for every 1 percentage point decline in intergenerational chronological correlation,the household savings rate increased by 0.17 percentage points.There are differences in the influence of intergenerational income mobility on household saving behavior of different types.Intergenerational income mobility has a more significant impact on the savings rate of low-income households than high-income ones.Intergenerational income mobility only affects the savings rate of households with boys,not those without.According to the empirical research conclusions,this paper puts forward three policy suggestions: first,focus on the intergenerational income mobility of the western region and the northeast region to prevent regional differences from being further widened;Second,we need to increase intergenerational income mobility,remove institutional barriers to social mobility,and ensure equitable development conditions for all.Third,increase public education expenditure,improve the education level of children living with them,increase the rate of return on education,alleviate the inhibiting effect of intergenerational income mobility on consumption,and better play the positive role of intergenerational income mobility in promoting social equity and economic development.
