| The disparity of regional economic development is a very common phenomenon and a hot spot for academic research,so how can we narrow the gap between regions and achieve common prosperity? From the perspective of economic growth,to achieve common prosperity,it is necessary to make the income of low-income groups grow faster than the general level,i.e.,to achieve economic pro-poor development,which is an important way to reach common prosperity.Based on the literature and theories about regional economic disparity and pro-poor development,this paper takes 16 states(cities)and 129 counties(cities and districts)in Yunnan Province as the spatial unit of analysis based on two scales: state(city)and county,and takes 2010-2020 as the research time period.Firstly,we quantitatively analyze the time evolution characteristics of absolute and relative differences of regional economic development in Yunnan Province by measuring the standard deviation of per capita GDP and the Thayer coefficient of 16 states(cities).Secondly,based on spatial correlation theory and spatial correlation analysis methods,global spatial autocorrelation method and local spatial autocorrelation method are chosen to explore the evolution process of spatial pattern of regional economic development in Yunnan Province.Then panel model is used to explore the influencing factors of regional economic differences in Yunnan Province.Finally,PGC indicators are used to identify and analyze the overall economic growth of Yunnan Province,and then the variation trend of regional economic differences in Yunnan Province is judged by Gini coefficient,and then the type of economic growth is compared with the trend of Gini coefficient,so as to sort out the interaction between the type of economic growth,regional economic disparity and poverty in Yunnan Province.We also analyze the factors influencing the regional economic development of Yunnan Province,and construct a binary Logit discrete model to explore the main reasons for the economic development of 16 states(cities)in Yunnan Province from 2011 to 2020,and obtain the following key conclusions.(1)In terms of time evolution characteristics,the absolute differences of regional economic differences in Yunnan will continue to widen while the relative differences will gradually decrease during the study period.In terms of economic differences at different geographical scales,regional economic differences in Yunnan province are affected by a combination of differences among states(cities)and differences among the 129 counties(cities and districts)within each state(city),but differences among states(cities)still have the most significant impact on overall economic differences in Yunnan province and will continue to influence the trend of overall differences.The results of the decomposition of the industrial structure of regional economic differences show that the output value of the tertiary industry is the main contributor to the total GDP of Yunnan Province,followed by the secondary industry.The concentration effect of the three industries is the main reason for the total difference.(2)From the spatial pattern evolution characteristics,the global Moran’s I values of per capita GDP of 129 counties(cities and districts)in Yunnan Province from 2010 to 2020 are all positive,indicating that there is a positive correlation in the spatial layout of economic and social development levels of counties in Yunnan Province,i.e.,there is an aggregation phenomenon of counties(cities and districts)with similar economic development levels,and the spatial difference characteristics It is obvious that central Yunnan,especially Wuhua District,Xishan District,Guandu District,Yiliang County and Fumin County under Kunming City,have been at the forefront of Yunnan’s economic development,while the economic development of northeast Yunnan,represented by Zhenxiong County and Weixin County under Zhaotong City,and Malipo County and Guangnan County in southwest Yunnan,is at a relatively backward level.(3)Based on the panel data of 16 states(cities)in Yunnan Province from 2010 to2020,the panel model is used to empirically analyze the factors affecting the differences in regional economic development in Yunnan,and it is found that: fiscal expenditure,industrial structure,market openness,retail sales of social consumer goods,science and technology development,human capital and fixed assets have a significant impact on the differences in regional economic development in Yunnan,and each factor combined Human capital has the greatest impact on Yunnan’s regional economic development,followed by the level of scientific research and industrial structure.(4)Lorenz curve fitting and improved poverty growth curve are used to test the pro-poor nature of economic growth in Yunnan Province.First,it can be found that:Yunnan’s economic development is generally pro-poor during 2010-2020,while its pro-poor intensity varies more significantly in each year.Second,except for a few years,the economic growth type in Yunnan Province is mainly pro-poor,and the regional differences tend to decrease significantly.The change of pro-poor growth curve shows a correspondence with the change of Gini coefficient,and the matching rate is as high as 80,i.e.,the pro-poorness of economic growth has an important influence on the evolution of regional differences and poverty.(5)According to the measured pro-poor economic growth in Yunnan Province,the pro-poor is recorded as 1 and the non-pro-poor is recorded as 0 as the explanatory variables.The empirical results show that economic growth,primary income distribution policy,re-income distribution policy and investment level have significant effects on the pro-poor growth of regional economy in Yunnan Province,and economic growth and average wage index of employees have pro-poor economic growth in Yunnan,while The fiscal expenditure on people’s livelihood and total investment in social fixed assets have a negative impact on Yunnan’s economic pro-poor growth.(6)Based on the above findings,specific countermeasures are proposed:reforming economic growth and implementing pro-poor development strategies;maintaining stable economic growth and increasing the economic benefits and participation of low-income people;focusing on the sustainability,fairness and precision of income distribution policies;improving the level of fixed asset investment and increasing the marginal benefits of capital;improving the quality of human resource and promoting the social human resource accumulation. |
