地区市场分割对创新数量、创新质量的影响机制研究

从创新数量与创新质量角度分析市场分割的影响机制、影响大小、影响规律具有重要意义。本文基于中国高技术产业统计年鉴数据,综合采用面板数据模型、面板门槛回归模型、贝叶斯向量自回归模型全面分析了市场分割与创新数量、创新质量之间的关系。研究结果表明:市场分割总体上与创新数量、创新质量无关,市场分割对创新的正向影响与负向影响产生的效应相当;市场分割越严重,对创新数量的正向影响越大,对创新质量的间接负向效应也越大;但市场分割也有积极的一面,表现为市场分割有利于低水平创新数量和创新质量地区创新;此外创新数量与创新质量具有一定的负向互动机制。

Market Segmentation and Innovation Quantity,Innovation Quality

It is of great significance to analyze the influence mechanism,size and rule of market segmentation from the perspectives of innovation quantity and innovation quality.Based on the Chinese high-tech industry statistic yearbooks,this paper comprehensively analyzes the relationship between market segmentation,innovation quantity and innovation quality by using panel data model,panel threshold regression model and Bayesian VAR(Vector Autoregressive)model.The results show that the market segmentation is generally unconcerned with the quantity and quality of innovation.The positive and negative effects of market segmentation on innovation are equivalent.The more serious the market segmentation is,the greater the positive effect on the quantity of innovation is,and the greater the indirect negative effect on the quality of innovation is.However,there also is a positive side to market segmentation,which is manifested by market segmentation is conducive to regional innovation of low-level innovation quantity and innovation quality.In addition,innovation quantity and innovation quality have certain negative interaction mechanism.
