Abstract:This paper constructs an evaluation index system of science and technology (S&T)innovation from three dimensions named as process-structure-time series.Based on the regional panel data of China from 2001 to 2021, the S&T innovation boom index of China's eight comprehensive economic zones is calculated by the composite index method.Taking it as the research object, we analyze the volatility and periodicity of S&T innovation in the whole country and eight comprehensive economic zones by combining the characteristics of physical waves.Kernel estimation and Dagum Gini coefficient and its decomposition method were used to describe the dynamic distribution characteristics and differences of S&T innovation in the whole country and eight economic zones.The results show that the fluctuation cycle of S&T innovation in the whole country and the eight comprehensive economic zones presents asymmetric characteristics during the observation period.The level of S&T innovation in the east-central and southeast is obviously better than that in the northeast and northwest economic zones.In recent 20 years, the fluctuation of S&T innovation level in the whole country and the eight comprehensive economic zones show kinds of cycle lengths, and the cycle characteristics are heterogeneous.The dynamic evolution characteristics of the level of S&T innovation in different regions are quite different, but the provinces with low level of S&T innovation in the region have a catch-up trend.Meanwhile, with the change of spatial lag type, the phenomenon of “club convergence”becomes more and more prominent, and the locking effect of S&T innovation level is strengthened, which makes the areas difficultly to realize leapfrog.The overall difference of S&T innovation level in the whole country and the eight comprehensive economic zones showed an obvious downward trend, but the difference between regions showed an expanding trend.The research value showed that the fluctuation of S&T innovation in different economic zones varies.Therefore, local conditions should be adapted to stimulate the vitality of S&T innovation in economic zones.Precise policies should be taken to provide quantitative basis for promoting the coordinated development and quality improvement of S&T innovation in different economic zones.
