Study On Transformation And Upgrading Of Tianjin's Manufacturing Industry

As the core industry,manufacturing is an important pillar of China's economic and social development.In recent years,the Chinese government,based on the general trend of international industrial transformation,has made major strategic arrangements to comprehensively improve the quality and level of development of China's manufacturing industry,striving to realize the transformation from a manufacturer of quantity to one of quality.As an industrial center in northern China,Tianjin's manufacturing industry has always occupied a large proportion and played a decisive role in the economic and social development of the region.In this context,Tianjin has put forward the strategic policy of transformation and upgrading of manufacturing industry,committed to building a national advanced manufacturing research and development base,and injected power into the transformation and upgrading of Tianjin manufacturing industry.However,as the international economic situation is sluggish and the domestic economic growth is slowing down,Tianjin's manufacturing industry is experiencing sluggish growth and declining profitability,and its development is facing difficulties.To reverse the decline of Tianjin's manufacturing industry and build a manufacturing industry with international competitiveness,we must speed up the transformation and upgrading of the manufacturing industry.Therefore,it is of great significance to strengthen the research on the transformation and upgrading of Tianjin's manufacturing industry.Based on the relevant theories of economics,this paper uses the method of literature research to sort out the relevant research results of manufacturing industry transformation and upgrading,and from the perspective of total factor productivity,analyzes the mechanism of technological efficiency and technological progress to promote the transformation and upgrading of manufacturing industry.On the basis of the above theoretical analysis,combined with the current development situation of Tianjin's manufacturing industry,it is revealed that the mode of relying on the input of factor resources to promote the development of manufacturing industry is no longer sustainable,and the promotion of total factor productivity will become a feasible path to promote the transformation and upgrading of manufacturing industry.In order to further explore the restrictive factors of Tianjin's manufacturing industrytransformation and upgrading,this paper uses DEA-Malmquist index method to estimate total factor productivity and its decomposition index of Tianjin's manufacturing industry based on the data of 28 above-scale manufacturing industries in Tianjin from 2010 to 2016.According to the results of empirical analysis,it is concluded that insufficient technological efficiency is the main reason for the lack of TFP,the speed of technological progress is slowing down and has a stagnant trend,and it is verified that insufficient technological innovation capability is the main factor restricting Tianjin's manufacturing industry transformation and upgrading.Finally,according to existing problems in the development of Tianjin's manufacturing industry and the results of empirical analysis,this paper puts forward several countermeasures and suggestions to promote the transformation and upgrading of manufacturing industry,in the view of the perspective of total factor productivity.Such as improving the technical efficiency of manufacturing enterprises,actively promoting technological innovation to accelerate technological progress,and promoting the optimal allocation of resources.
