摘要
创新是高质量发展的第一动力,但是,创新质量本身缺少系统研究。从投入产出过程角度看,创新质量分为研发投入的知识产出质量和知识投入的经济产出质量两个阶段,基于马尔可夫区制转换向量自回归模型(MS-VAR)对中国及其分区1995-2021年时间序列数据进行检验,揭示投入产出过程创新质量演化阶段性及其区域异质性。研究发现:目前我国处于新的创新质量快速提升期。R&D投入强度的增加会促进专利产出质量,专利产出质量的增加也会促进新产品销售收入。前者在创新质量快速提升期更显著,后者在创新质量稳定发展期更显著。四大地区①的创新周期具有时间先后性,东部地区最早进入创新质量稳定发展期,西部地区最晚;两次过程中,创新投入产出质量之间正向效应的区域异质性和区制异质性并存;但处于创新质量稳定发展期的西部地区两种投入产出效应都为负。
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.
