Study on the Characteristics of Information Service Industry in Yangtze River Delta

摘要

The information service industry is regarded as one of the new poles of growth for China's economy with much more effective productivity of factors and it is overall most competitive in the Yangtze River Delta region. In this paper, the quantitative analysis of total factor productivity (TFP) growth and development factors in Yangtze River Delta were calculated and analyzed by DEA-Malmquist index method and Solow residual value method. It was found that from "11th Five" to "12th Five" period, the fixed capital and labor investment growth was higher, but the TFP growth was insufficient, which means that it was still in the early stages of development, subject to the constraints of resources, the limitations of labor quality and the lack of technological innovation. However, with the capital marginal returns diminishing, labor quality improving and technological innovation booming, the development of information service industry will gradually move towards the top of the industrial chain and value chain with will total factor productivity rapidly improvement.
