Empirical Study On Regional Innovation Ability Of Chongqing Based On Data Envelopment Analysis

With the rapid development of science and technology, the way of economic growth changing constantly, the economic development has shown a strong regional characteristics. And the regional innovation capability has become a decisive factor for regional economic to obtain a competitive advantage and an important indicator of the competitiveness of regional competition participants.As one of the four municipalities and the core of China's five largest cities in 2010, Chongqing is the western leading city truly and shoulder the important task that leads the Western towards innovation and development road. Scientific and technological resources of the input and output capacity is the key to impact the regional innovation capability. But at present, Chongqing regional innovation system there is some bad phenomenons of inadequate investment in innovation resources, fragmentation, duplication of investment and inefficient configuration in the development process. That handicap the construction and development of Chongqing regional innovation system severely. So it is necessary to understand the construction and development of Chongqing regional innovation system deeply, surveying and analysising the input, efficiency, overall planning and optimizing the allocation of technology resources especially. Then according to the characteristics of regional innovation system and the needs of science and technology resources for social development in Chongqing, combinating the existing practical experience and research results, throughing the appropriate mechanism designed, to stimulate regional cooperation within the main elements and to achieve the aim that increasing efficiency and overall planning and optimizing the allocation of technology resources.In this paper, we get 9 principal components through using the PCA to analyse the 144 innovation ability evaluation indicators which are designated by China Technology Development Strategy Research Group firstly. That is 5 input indicators: research and development staff full-time equivalent, science and technology input of government, the number of high-tech enterprises, expenditure on education, the number of technology centers or research institutes of medium-sized industrial enterprises, and 4 output indicators: technology market turnover, the number of invention patents, the value-added of the tertiary industry and the number of domestic and international paper. Secondly, through using the method of data envelopment analysis to analyze the regional innovation efficiency in Chongqing, the empirical results show that the value ofθis 0.87, less than 1. That means Chongqing regional innovation system is non-DEA efficience. Meanwhile, the value ofθof Chongqing is Minimum in the four cities and shows that Chongqing regional innovation system has the least efficient. Scale efficiency results of the analysis show that Chongqing regional innovation system is still in incremental stages of scale and has huge development potential. The results of difference analysis indicate the reasons which led to low efficiency of regional innovation in Chongqing and give a way how to improve efficiency. Thirdly, according to the direction given by difference analysis, to explore the policies which can be implemented. Then combining the results of previous studies and quantitativing policy targets, especially focusing on the government R&D subsidy policies based on the supply chain. Finally, combinating the conclusions of differences analysis and quantitative analysis, and giving some policy recommendations which supported by the theories for Chongqing government.
