Stages of Innovation Quality Evolution and Regional Heterogeneity in China Based on MS-VAR Modeling
Innovation is the first driving force for high-quality development,but the quality of innovation itself lacks systematic research.The paper divides the quality of innovation into two stages from the perspective of input-output process,namely,the quality of knowledge output of R&D input and the quality of economic output of knowledge input,and examines the national and four major regions'innovation time-series data from 1995 to 2021 based on the Markov System of Regions Switching Vector Autoregression(MS-VAR)model,to reveal the evolution of the quality of innovation in the input-output process stages and its regional heterogeneity.The study finds that China is now in a new period of rapid improvement in innovation quality,where an increase in R&D input intensity promotes the quality of patent output,and an increase in the quality of patent output also promotes the income from the sale of new products.The former is more significant in the period of rapid improvement of innovation quality,and the latter is more significant in the period of stable development of innovation quality.The innovation cycles of the four regions have obvious time sequentiality,the first region to enter the period of stable development of innovation quality is the eastern region,and the slowest is the western region;the positive effect of innovation input quality on innovation output quality in the two innovation input-output processes coexists with regional variability and regional system variability;the western region,which is in the period of stable development of innovation quality,has a negative effect on both inputs and outputs.
