Industrial Structural Changes, Technological Progress And Regional Economic Growth

China’s economic development has experienced 30 years of rapid growth since the reform and opening, to 2008 its economic growth slow down to 9.6%, and in 2014 it further down to 7% growth. Clearly, China’s economic growth has slow down from the rapid growth to the new normal speed, China’s economic growth and sustainable development has draw China and other international community’s increasing attention.Earlier studies have considered that the growth pattern of East Asia is based on the input of capital, labor and other factors, so it lack lasting power,economic,and is considered to be unsustainable. The effect of industrial structure change and technological progress is the main reference index to measure the region economic growth is sustainable or unsustainable. The domestic scholars studied in this point of view, although China’s economic growth in the structural change effect is declining, but the effect of technological progress is still very clear, and it is a sustained upward trend, so that China’s economic development is a sustained growth conditions. So for the Yangtze River Delta economic circle, economy is in what conditions? As is known to all, the Yangtze River Delta economic circle is China’s largest economic zone, its market mechanism and technical level is ahead of other regions, with a typical representative, its economic development is related to the eastern coastal areas and the nation economic development,represent the sustainable development of the nation economy. Therefore, this article starts from the perspective of economic growth in the Yangtze River Delta economic, so as to explore the economic growth sustaintability of the Yangtze River Delta economic, and ultimately provide a reference for the future economic and industrial policy to develop sustainable economic.Firstly, this thesis uses Shift-Share Analysis to decompose the industrial structure change effect and the effect of technological progress in the growth of labor productivity, and get the contribution of these two effects to the labor productivity and its long-term trend. Secondly, it analyzes the influence of labor productivity on regional economic growth. Finally, using the method of measurement, combined with the structural effect matrix, so as to conclude the industrial structure change effect and technology progress effect on the economic growth of the Yangtze River Delta economic circle.Empirical research shows that, compared with the third industry, the industrial structure change effects of the first and two industries are not significant. The effect of industrial structure change on the economic development of the Yangtze River Delta economic development is not significant.So the Yangtze River Delta economic development is sustaintable.Finally, the article put forward recommendation from the deepening of market reform, enhance R & D investment, promote scientific and technological innovation, continue to deepen industrial restructuring, promote industrial structure optimization and other aspects of the policy recommendations. And put forward research prospects from the perspective of increasing the depth and breadth of the contrast range, the influence of the optimal allocation of capital factors on regional economic growth, and the research on the quantitative index of technological progress, etc.
