A Study On The Evaluation And Promotion Of China 's Economic Growth Under The New Normality

China is at a transitional stage of economic development currently. The rate of economic development becomes slow and the proportion of consumption increases. Economic growth shows new features as high speed, excellent structure, new power and many challenges. Chinese economic development has entered a "new normal". People are more concerned about the quality than the quantity of economic growth.Under this background, this paper do something research about status at home and abroad and define the connotation of economic growth quality firstly. Secondly, this paper analyzes on the factors which influence the quality of economic growth through the theoretical and mathematical analysis. Conclusion is that the investment structure is the main factors influencing the quality of economic growth. When the quality of economic growth is maximized, the ratio between per human capital per natural capital and per social capital is equal to the output elasticity ratio. The ratio of consumption and the ratio of material capital divide human capital are negatively related. Per human capital, per social capital and the per natural capital increase will make further improve the quality of economic growth, but only to increase the per material capital investment can’t cause a ascension in the quality of economic growth. At last this paper build an index system for evaluating the quality of economic growth. GML index are took to make the evaluation of quality of economic growth in 30 Chinese provinces and the factor decomposition from 2000 to 2013. Result showed that the quality of China economic growth gradually slowed down, and the quality of economic growth steadily improve. Technical efficiency and scale efficiency is the main factor to limit the growth of quality of economic; Technical progress and technical progress the scale efficiency are the main sources of improve the quality of economic growth and the quality of economic growth of eastern region enhances higher than the central and western region. Investment in China is not only the motive of economic growth, but also driving source of economic growth quality. In the future Chinese economic growth, efforts should be made to improve the technical progress efficiency and scale efficiency of technical progress, promote the role of technological progress in economic growth, reduce the cost of economic growth, and achieve the unity of economic growth quantity, quality and efficiency.
