| The consumption structure is an important indicator used to reflect the consumption characteristics of residents and measure the living standard and quality of residents.It can also be used to reflect the economic development level of a country or region.For the three northeastern provinces as traditional old industrial bases,the glory of the past is a thing of the past.Nowadays,the economy in the northeast region is sluggish.There are many problems in the consumption structure of residents.The economic development is relatively backward.The problem is outstanding.With the advancement of urbanization,there are more and more urban populations.Studying the optimization of the consumption structure of urban residents has a certain guiding role in optimizing the consumption structure of rural residents.Therefore,it is extremely important to study the optimization of the consumption structure of urban residents in the three northeastern provinces,and try to find out the current problems and give corresponding optimization suggestions in order to promote the development of the national economy of the three northeastern provinces.Starting from the definition of the connotation of consumption structure and consumption structure optimization,the relevant theories of consumption structure optimization are systematically sorted out,and the physiological,economic and social standards of consumption structure optimization are proposed.Based on these three standards,the Engel Coefficient,proportion of clothing expenditure per capita,consumption income elasticity,consumer price index,social security coverage rate and other 12 secondary indicators of the consumption structure optimization evaluation index system,using factor analysis method,the overall optimization of urban residents' consumption structure in the three northeastern provinces The process was empirically analyzed,and the differences in the optimization processes among the three provinces in Northeast China were compared and analyzed.According to the overall analysis,The level of urban residents 'consumption structure optimization in the three northeastern provinces has risen in a wave-like manner.The development at the three levels of physiology,economy,and society is uncoordinated.The weak economic development has always been the main factor hindering the optimization of urban residents' consumption structure.When comparing and analyzing the consumption structure of urban residents in the three northeastern provinces,it is found that among the three northeastern provinces,the process of optimizing the consumption structure of urban residents in Liaoning Province is the fastest,followed by Heilongjiang,and the slowest in the optimization process of Jilin,and the factors restricting the optimization of the consumptionstructure of the three provinces are different.Finally,based on the results of empirical analysis,some problems in the consumption structure of urban residents in the three northeastern provinces were found,and it was proposed that the consumption structure of urban residents could be optimized by increasing the income level of urban residents,guiding the transformation of consumption structure,promoting economic transformation,and improving the social security system.At present,there are many literatures on the optimization of consumption structure in foreign countries,but most of them are relatively one-sided.Therefore,the article uses the method of factor analysis to establish a comprehensive evaluation index system for the urban residents' consumption structure in the three northeastern provinces,which is scientific and reasonable.By studying the optimization of the consumption structure of urban residents in the three northeastern provinces,it will not only further promote the economic development of the three northeastern provinces and improve the living standards of residents,but also provide a certain reference for the optimization of the consumption structure of residents in other regions. |
