Research on Dynamic Change of China's Regional Innovation Efficiency-Based on Malmquist Index

並列摘要


In constructing the panel data of 30 provinces from 1998 to 2010, this paper constructs provincial innovation activities in the production frontier based on Malmquist Index and DEA Model, decomposing the innovation efficiency growth into technological progress and technical efficiency change. The paper also investigates regional innovation sources of growth and differentiation. The results show that: (1) The innovation TFP growth not only comes from technological progress, but also from technical efficiency, and the contribution of technical efficiency is slightly greater than that of technological progress from 1998 to 2010. Technology efficiency growth is mainly caused by the growth of pure technical efficiency, in spite of the decline of scale efficiency. (2) The innovation TFP growth is relatively stable after 2000, except for a decline during 2003-2005. The technology efficiency change reached the top in 2002 and had grown steadily after that. The technology progress change always grows steadily except for a decline in 2002. (3) The TFP growth annually of the East, Middle and West is 1.019, 1.008 and 1.015 respectively. There exists gap between Eastern and Mid-Western, and the gap between the Middle and Eastern is bigger than the Western and Eastern. The TFP growth of eastern region mainly comes from technological progress, while the TFP growth of central and western mainly comes from technical efficiency.
