生态学视角下的现代服务业集群最优规模的确定

摘要

This article analyzes the life cycle of modern service industry cluster from the perspective of ecology and finds that modern service industry cluster is also subject to the negative feedback mechanism, which adjusts the increase or decrease of the population number in the system so as to keep its dynamic balance in which a cyclic process of “balanced-unbalanced-balanced” maintains. It further explains by the logistic equation that with the limited social, economic, technological and ecological resources, modern service industry cluster is always restricted by a certain threshold value, which in turn determines the optimal scale of modern service industry cluster under certain time-space conditions.%从生态学的角度研究分析了现代服务业集群的生命周期，认为现代服务业集群中同样存在着一种负反馈机制，调节着系统中种群数量的增减，使之维持动态平衡，即认为现代服务业集群发展过程是一种“均衡-非均衡-均衡”的循环反复的过程。文章借用逻辑斯蒂方程进一步解释说明，即在有限的社会、经济、技术和生态资源下，现代服务业集群总会受某一阈值的制约，而由此形成的每一次均衡即是现代服务业集群在特定时空条件下的最优规模。
