An Analysis on the Effects of Population Structure on Yangtze River Delta's Economic Growth

From the angle of the changes in population structure,this paper sets Yangtze River Delta as the target area and analyzes the evolution characters of population structure in terms of age,culture,urban-rural duality,industry,unemployment,occupation and sex,and their effects on economic growth.Then it uses the panel data from 1978 to 2010 to discuss the population structure factors which give rise to Yangtze River Delta's economic growth.It draws the following conclusions:firstly,on the whole,the changes in population structure correspond to the adjustment to economic structure,and the changes in population age,urban-rural dual,cultural and industrial structures help support Yangtze River Delta's economic growth,while the changes in population occupational structure hold back Yangtze River Delta's economic growth;secondly,with regard to different provinces and cities,the effects of the changes in population structure on regional economic growth differ;thirdly,as some down pressure of the excessive population growth on productivity has been greatly eased,the population structure has been a big real problem that restricts the economic and social development on Yangtze River Delta,which should attract enough attention from the decision-making sectors.When solving the population problem,governments should implement differentiated control policies in accordance with regional economic development.
