Analysis Of The Impact Of Total Factor Productivity On Yunnan Economic Growth From The Perspective Of Industrial Correlation

Yunnan Province is located in the mountainous area of the southwestern border of China.Compared with the mainland,the innate conditions for economic development are insufficient,and it is more challenging to develop the economy.Along with the Chinese economy entering the new normal phase,the target of the Yunnan Provincial Government is that compared with 2010,Yunnan Province will achieve a quadrupling of regional GDP,and the income of urban and rural residents will triple in 2020,and step into a comprehensive well-off society.At the same time,it proposes to develop eight key industries and build a new industrial system development strategy.In the context of downward pressure on the domestic economy,it is a long-term and arduous task to realize the strategic goals of Yunnan Province.Therefore,it is particularly urgent to study the sources of economic growth among industries.In this regard,from the perspective of industrial linkage,this paper first analyzes the correlation effect of industry and analyzes the correlation effect and proximity between industry and industry,and expresses the simulated industry in spatial geography with the direct consumption coefficient between industries.Secondly,the panel data of 30 industries in Yunnan Province from 2004 to 2017 are taken as observation samples,and the direct consumption coefficient table between industries is used as the spatial weight matrix.The spatial econometrics model is used to empirically analyze the impact of total factor productivity on Yunnan's economic growth.Through relevant economic theoretical and empirical analysis,the paper summarizes the following conclusions.The first conclusion is about the level of total factor productivity.The total trend of total factor productivity in Yunnan Province between 2004 and 2017 is growing.Between 2004 and 2008,the level of total factor productivity has been in the growth phase until reaching its highest level in 2008.With the outbreak of the global financial crisis in 2008,the level of total factor productivity in Yunnan Province began to decline in 2009,and there was a negative growth in 2013.From then on,with the change of national development policies and the transformation of economic development mode,Yunnan province's total factor productivity level is in a relatively stable state.The second conclusion is about the spillover effect of economic growth between industries.In this paper,the spatial weight matrix is constructed by the direct consumption coefficient matrix.After the spatial autocorrelation statistical test,the motivation of the spillover effect is analyzed.The results show that there is a significant spillover effect on economic growth among various industries in Yunnan Province.This effect is mainly caused by the correlation of random disturbances.Capital investment and labor input along with total factor productivity have no direct spillover effect on related industries in the industrial space,but only weak indirect spillover effects.The third conclusion is in aspects of the factors affecting economic growth.From the results of the model,total factor productivity,labor input and capital investment will positively promote the economic development level of the industry.Among them,labor input has the greatest promotion effect,followed by capital investment and finally total factor productivity.Based on the above research results,this paper puts forward the following suggestions.First,optimize the industrial structure and promote the transformation of the industrial structure.Second,extend the industrial chain in combination with key industries.Third,improve the quality of human capital and rationally allocate of human resources.
