Abstract: Based on Technology Achievement Index of China's 21 national innovative cities during 2001-2009, this article chooses Technology Achievement Index as target variables and six predictor variables reflecting the initial level of regional innovation capacity and regional economic structure characteristics to gain the optimal regional groupings, which match the definition of club convergence better. Combining the endogenous CART methods with Theil index test and random convergence unit root test, this article conducts club convergence test for the level of technical achievement of 21 national innovative cities. The results show that: (1) though the overall Technology Achievement Index of 21 national innovative cities is growing, the difference is becoming larger during the sample period; (2) government intervention and regional technological progress are the most important grouping variables, this also indicates that the development of innovative cities has a distinct characteristic of government-driving; (3) According to the similarity of government intervention and regional technical progress, 21 national innovative cities can be divided into three clubs endogenously. Shenzhen still leads the process of innovative city in China; then seven cities, such as Beijing, Shanghai, represent a convergence club of relatively higher level of technical achievement; the rest other cities forms the last club.
