创新生态系统中两斑块种群关系研究-以江苏、浙江的工业企业为例

Study on the Population Relationship of Two Patches in Innovation Ecosystem——A case study of industrial enterprises in Jiangsu province and Zhejiang province

基于生态学原理,构建两斑块种群竞争模型.以江苏省和浙江省两斑块内工业企业为研究对象,分析工业企业种群竞争关系.浙江省工业企业种群内部互动关系显著,且呈现明显的协同关系.江苏省工业企业种群内部互动关系不显著.logistic模型和竞争度模型测算结果均表明江苏省和浙江省的工业企业竞争关系不强.测算两斑块工业企业种群投入产出指标的Malmquist指数,得到全要素生产率、技术进步和效率的变化趋势.发现工业企业协同效应促进了效率的提高,协同效应没有促进技术进步.

The population competition model of two patches was constructed based on the principle of ecology.The paper analyzes the competitive relationship of industrial enterprises in the two patches of Jiangsu province and Zhejiang Province.The local internal interaction relationship of industrial enterprises in Zhejiang province is significant and shows obvious cooperative relationship.The local internal interaction relationship of industrial enterprises in Jiangsu is not significant.The results of logistic model and competition degree model show that the competitive relationship between Jiangsu province and Zhejiang province is not strong.The paper calculates the Malmquist index of input-output index of industrial enterprises in the two patches,gets the change of total factor productivity,technical progress and efficiency.The synergistic effect of industrial enterprises in the two patches promotes the improvement of efficiency.Synergy does not promote technological progress.
