The Relation between Age Structure of Population and Resident Consumption Based on Endogenous Growth Theory

Within the framework of endogenous growth theory,the dynamic relation between age structure of population and resident consumption was studied,and explicit relation between resident consumption and dependency coefficient was obtained through Hamiltonian function method. Then,an empirical study was carried out based on panel data of 31 provinces of China in 2000-2013. The study gave following results: there is negative correlation between child dependency coefficient and resident consumption and there is positive correlation between elderly dependency coefficient and resident consumption; urbanization level weakens the negative effect of child dependency coefficient on resident consumption but it increases the positive effect of elderly dependency coefficient on resident consumption; social expenditure weakens the negative effect of child dependency coefficient on resident consumption,but it intensifies positive effect of elderly dependency coefficient on resident consumption. These results indicate that current population structure of China is favorable for growth of resident consumption demand,but in such aging population structure,economic development may lose demographic dividends.

Research on the Influence of the Digital Economy on Transforming Consumption Behavior Among Residents

Drawing on the essence of Marxist consumer economy theory,this paper argues that the innovations of digital technology can effectively facilitate the integration of economies of scale,economies of scope,and long-tail economies.Through careful analysis of the practical case of Xiaomi’s business ecosystem,this paper highlights the notion that data serve as both a key production factor and a critical consumption carrier within the context of digital consumption.We thoroughly investigated the influence of the digital economy on transforming consumption behavior among residents by analyzing a range of typical business cases and the latest data that triggered this transformation.Based on the analysis,this paper argues that such transformation can lead to the platform agglomeration effect,the inclusive diffusion effect,and the push-pull effect by highlighting the specific ways in which the digital economy disrupts the consumption-production model and contributes to the upgrading and transformation of traditional industries.Additionally,this paper demonstrates how the digital economy can expand and promote emerging business forms,providing insights into the ways in which digital innovation is reshaping the contemporary economic landscape.This study intends to provide several policy suggestions that can expand domestic demand,promote consumption,drive the high-quality and integrated development of China’s digital and real economy,and position China as a strong cyber and consumer nation by using digitalized consumption as a starting point.

Empirical Analysis on the Relations between Rural Residents' Consumption and Economic Growth——A Case of Liaoning Province

Liaoning is a granary province with a large agricultural population and great market potential. Expanding rural residents' consumption becomes a necessity for enlarging domestic demand, solving three agriculture problems and promoting sustainable and rapid economic development. The research shows that since invigorating old industrial base in Liaoning, the contribution rate of rural residents' consumption to economic motivation is low and unstable, which has become one of the choke points for the development of economy. By using the grey correlation method, the influences of rural residents' consumption in different periods to GDP per capita are analyzed, the results show that the consumption level of rural residents were increasing, but their contribution rate on economic growth showed the descending tend. The residential expenses stay in the major position of consumption expenses; the education and entertainment products and service consumption play an important role; the growth of transportation and telecommunication is slow; the expenses on medical care are low and its contribution rate on economic growth is relatively weak. The countermeasures on developing rural economy, increasing rural residents' income, improving rural consumption environment, accelerating rural infrastructure construction, constructing and perfecting rural social security system and expanding rural consumption credit market are put forward to expand rural residents' consumption demand and realize the sustainable development of economy.

Influence of Aging Trend on Consumption Rate of Rural Residents--Empirical Analysis Based on Provincial Panel Data

Population is a basic factor that affects consumption of residents. In China,insufficient demand of residents,especially low consumption demand of rural residents,directly weakens the promotion of consumption for economic growth. This drives the study on the relationship between the aging trend and consumption of rural residents. In this paper,the current situation of population aging in China was firstly analyzed. Then a dynamic macroeconomic model was established using the cointegration theory and selecting related time series data such as per capita consumption expenditure of rural residents( Con),per capita net income of rural residents( Rev),urban-rural income gap( RU),children dependency ratio( CDR),and old-age dependency ratio( ODR),to test the correlation between variables. The results show that the decline in the children dependency ratio promotes the increase of consumption willingness of rural residents,while the rise in the old-age dependency ratio inhibits the consumption willingness of rural residents. Finally,it came up with pertinent recommendations for guiding and promoting the consumption level of rural residents in China.

Empirical Study on the Relationship between Income and Consumption of Rural Residents in Hebei Province

Based on the relevant data of the actual income and consumption of rural residents in Hebei Province from 1983 to 2007,the relationship between actual income and consumption of rural residents was tested by applying the co-integration theory and Granger causality test.The result shows that there is long-term stable equilibrium relationship between the net Income per capita and consumption expenditure per capita of rural residents in Hebei Province from 1983 to 2007;the result of Granger causality test shows that the actual Income of rural residents in Hebei Province has significant impact on the actual consumption,but the impact is weakened gradually;in short term,the impact of the actual consumption on the actual income is not so significant,but the impact will become significant gradually as time goes on.During the process of the mutual impact and function of the actual income and consumption of rural residents in Hebei Province,the impact of the actual income of rural residents on the actual consumption is mainly represented in short term;in middle term,the interactions between the actual Income and actual consumption are significant;in long term,the impact of the actual consumption on the actual income is mainly displayed.According to the result,in short term the government in Hebei Province can expand consumption through increasing the income of rural residents,while in long term the government can drive the economic growth by expanding domestic demands.

The Influence of Economic Policy Uncertainty and Habit Formation on Rural Residents’ Consumption

Based on the household survey data of rural residents in 30 provinces(cities,districts)of China from 1995 to 2019,this paper constructs an econometric model of farmers’consumption behavior with habit formation and economic policy uncertainty,and makes an empirical analysis of farmers’consumption behavior by using sys-gmm estimation method.The results show that:since the reform and opening up,the changes of Chinese farmers’consumption behavior not only show excessive sensitivity to income changes on the whole,but also show a significant habit forming effect,and the existence of habit effect will reduce the impact of economic policy uncertainty on consumption;there is a large gap between regions,and the consumption in the western region is affected by the uncertainty of economic policy,the impact is greater.Therefore,the government should pay attention to the impact of economic shock on consumption,maintain the systematicness and stability of the policy,enhance the stability,continuity and accuracy of the policy,drive the development of the western region,build a long-term policy mechanism to promote the sustained and rapid increase of farmers’income,and further change farmers’consumption concept.

Optimal City Size in China:An Extended Empirical Study from the Perspective of Energy Consumption

The optimal city size has always been a heated topic for debate in China. Given the background of global warming and fossil fuel crisis, it is argued that the issue should be considered from not only the perspective of economic benefits of a city but should also consider the energy consumption efficiency of the city. On the basis of the energy consumption data of 286 cities at the prefectural level and above in Chinese mainland except Lasa, which are obtained from the EU Emission Database for Global Atmospheric Research(EDGAR), this paper carries out an empirical analysis on the relationship between the city size and the energy consumption efficiency of the city. Then based on this analysis, the paper further examines the economic benefits, social benefits, and environment quality of cities in different scales, and the findings reveal that large cities with 2 – 5 million population have the highest efficiency in all these aspects.
