摘要
基于创新生态理论和Lotka-Volterra模型,构建高技术产业技术自主研发、技术改造与技术引进3种技术创新方式间的生态关系模型,以《中国高技术产业统计年鉴》中技术创新相关数据为样本进行实证研究,基于模型参数估计值,从自然增长率、规模限制性数、相互作用关系3个方面分析高技术产业技术创新生态关系。结果表明:高技术产业整体自主研发与技术改造的生态关系是偏利技术改造竞争,自主研发与技术引进的生态关系是协同共赢,技术改造与技术引进的生态关系是偏利技术改造竞争;不同高技术产业细分行业3种技术创新方式生态关系的差异性较大。
From the perspective of technology innovation input,through using technical innovation ecological characteristics and Lotka-Volterra model,this paper constructs a model of independent R&D(RD),Technology Renovation(TR)and Technology Import(TI),and based on the data of China statistics yearbook on hi-tech industry,makes empirical research to analyze the ecological relationship of China’s hi-tech industry.The study draws two conclusions.First,in high-tech industry overall TR can restrain RD,and RD can promote TR,and RD can promote TI and TI can promote RD,TI can promote TR and TR can restrain TI.Second,there are huge differences of ecological relationship of technology innovation in high-tech segment industry.This study has some directive significance for the optimization and adjustment of technological innovation in China’s hi-tech industries.
