A Non-parametric Malmquist Index and Impulse Response Approach to Measuring Technology Progress among Yangtze Delta Intra-Region

Intra-regionization plays an important role in the regional development. How to improve the effectiveness of overall technology growth is an important issue which China's regional coordinated strategies need to solve. With the increasing intra-regional economic competition, "Yangtze Delta" has becomes an important growth pole. In order to investigate the technology trend of "Yangtze Delta", impulse responses function in the VAR model is used to simulate the accumulation effect and spillover effect across "Yangtze Delta". The empirical results indicate that there exists dynamic linkage effect during the process of technology interaction. Technology progress of shanghai not only strengthens the technology itself through "accumulation effect", but also generates "spillover effect" resulting in stimulation of innovation ability of Jiangsu and Zhejiang. Technology coordination model of "Yangtze Delta" brings enlightenment to the improvement of other region technology strategies as well as of nationwide regional coordinated strategies.
