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.
Based on the ecological theory, a two-patch competition model was constructed.Studying the industrial competition among industrial enterprises in Jiangsu and Zhejiang Provinces, the interaction among industrial enterprises in Zhejiang Province was significant and significant Synergy relationship.The internal interaction of the industrial enterprises in Jiangsu Province is not significant.logistic model and the results of the competitiveness model show that the competition between industrial enterprises in Jiangsu Province and Zhejiang Province is not strong.Identifying the input and output indicators of two-planed industrial enterprises Malmquist Index, we get the trend of total factor productivity, technological progress and efficiency.It is found that the synergistic effect of industrial enterprises promotes the improvement of efficiency and the synergistic effect does not promote technological progress.
