Study Of Industrial TFP Including Carbon Dioxide Emissions In Yangtze River Delta Cities

China’s Yangtze River delta region has superior natural conditions and economic strategic position. It has gradually developed into an industrial concentration area and a manufacturing center with high active degree, strong comprehensive strength. Since 1990, the proportion of GDP in Yangtze river delta region has been gradually increased. Total industrial output value in 2006-2013 increased from 9.02 trillion yuan to 23.2 trillion yuan, the rate of increase is 156.7%. For a long time, the industrialization level of Yangtze River delta is significantly ahead of the national level, industry is in the high-speed development period, and most cities have entered the middle stage of industrialization, however at the same time, the energy demand is increased accordingly. While energy consumption of the secondary sector is dominant, especially industry,which accounts for about 80%, resulting in large number of carbon emissions. So industrial sector inevitably becomes the primary object of deceasing energy consumption and improving energy efficiency. Improving the total factor productivity and reducing the impact of carbon emissions are becoming the internal requirement for the sustainable development of economy and environment. The economic growth mode of Yangtze river delta in general is still growth, energy-saving technology equipment and level of carbon emission reduction technology are still relatively backward. There still exists bottleneck in technology and capital.This paper is based on the total factor productivity, considering the factor of production inputs such as labor, capital, and environmental constraints, which is carbon emission. Firstly the paper adds industrial carbon emissions and energy consumption to the calculation of DEA-Malmquist productivity model, then uses industrial input and output data of 14 cities and industrial divisions’ data of two provincial capital city to figure out industrial total factor productivity. Which can measure the coordination of industrial economic development,resource saving and environmental protection. Secondly, it analyses the convergence and difference of dynamic evolution process between cities’ industrial TFP considering the carbon emissions. Finally using the panel model and regression model, study the influence factors of industrial total factor productivity in Yangtze river delta.Which helps to further understand how to realize saving energy, reducing consumption and enhancing the level of productivity,also has a strong practical significance in the development of low carbon economy.Through the analysis of theoretical and empirical research, this paper gets the following conclusions:During the sample period, the industrial total factor productivity considering carbon emissions of Yangtze river delta changes from 0.97 to 1.056, increased by 8.6%. The technical progress makes the most contribution for productivity growth, and negative technical efficiency shows the degradation phenomenon. From the perspective of specific cities, most of the cities’ Tfpch index show a trend of rise in volatility, which have different time point of decline. Most of the 14 cities in Yangtze river delta have Tfpch index which are greater than 1 and achieve DEA effective, except Suzhou, Changzhou, Ningbo,Taizhou,whose level are less than 1 and show a downward trend. From the perspective of industrial divisions in two provincial cities, Tfpch values of Hangzhou’s 33 industry declinein volatility, the advance of technique level promotes the productivity, but the technical efficiency still needs to be improved. Tfpch values of Nanjing’s 33 industry also fall in volatility, the technological progress has played a more important role than technical efficiency.In addition, industrial TFP considering carbon emissions in Yangtze river delta show obvious beta convergence and absolute convergence.The growth rate of cities which have the higher productivity is improving slower than the cities of lower productivity. "Catch-up effect" play a role, and the convergence rate is 6.4%, the half time to a steady-state level is nine years. Epanechikov kernel function of the density distribution displays an overall growth trend, but stability is not enough, regional productivity is in the situation of divergence. Panel model analysis of the factors affecting the results shows that the industrial structure, industrial property rights structure, foreign industrial scale share, level of open strategy have a positive impact on the industrial TFP considering carbon emissions in Yangtze river delta. Industrial energy structure, light and heavy industrial structure, the industrial energy intensity have a negative impact.Based on the above research, the paper puts forward countermeasures from the following aspects: improving in productivity, adjusting the industrial structure, optimizing the energy structure, optimizing the ownership structure, improving the level of research and development, and setting up a communication mechanism. So that the development of industrial economy in Yangtze River delta can be healthy and better through comprehensive effects.
