借助生物生态位理论对典型企业群落的企业生态位进行测度,并据此对群落内的关键种企业进行识别;采用物种生态关联度计算方法对典型企业群落的生态、产业关联度进行测算,结合企业群落内的企业类数、有无机构规划和投入等因素,应用因素关联分析方法对关键种企业的存在和作用前提进行分析。研究发现,企业群落内的产业关联和生态关联对企业生态位以及关键种企业的形成具有正向促进作用;就关键种企业的形成条件而言,无论企业群落规模和企业种数有多大,只有当企业之间在产业链上能做到共生与互补(生态关联)时,范围广、频度高的生态产业活动才更有可能出现,继而作为主导群落内副产品、废料交换的关键种企业才能因此产生。研究结果对认识和把握生态工业发展的本质具有重要的启示作用。
Based on the theory of bio-niche, the ecological niche of typical business community is measured, and the key enterprises in the community are identified accordingly. The ecological and industrial correlations of typical business communities are calculated by means of species ecological relevance calculation Business community within the number of enterprises, with or without agency planning and input and other factors, the application of factor analysis method to analyze the existence of key enterprises and the role of the premise. The study found that the industrial association and ecological relationship within the community have positive effect on the niche of enterprises and the formation of key kinds of enterprises. For the formation conditions of key kinds of enterprises, no matter the size of enterprises and the number of enterprises, only When enterprises can make symbiosis and complementarity (eco-related) in the industrial chain, a wide range of high-frequency eco-industrial activities are more likely to emerge, and then the key enterprises capable of swapping out by-products and wastes in the dominant communities will be able Therefore produced. The research results have an important enlightenment on understanding and grasping the essence of eco-industrial development.
