安徽省制造业与生产性服务业共生模式判定:理论与经验研究

Symbiosis Model Determination of Anhui Province Manufacturing Industry and Producer Service Industry: Theoretical and Empirical Research

本文借鉴Logistic模型对制造业与生产性服务业共生度进行理论界定,分别讨论了水平竞争、水平协作和垂直协作三种情形下模型的均衡解。研究发现,存在水平竞争关系的产业构成的共生系统,产业平衡规模水平是由外生的资源供给和产业相互影响系数内生决定,与共生单元产业固有的成长率无关;对称互惠共生均衡调整时间短且均衡稳定,而非对称互惠共生均衡调整缓慢且不稳定。建立计量模型,估算出1992—2012年间安徽省制造业和生产性服务业共生度并对二者共生模式进行经验判定。目前安徽省制造业和生产性服务业正处在非对称互惠共生向对称互惠共生转变。

This paper uses Logistic model to determine theoretically the symbiosis degree of manufacturing and producer services, discusses the equilibrium solution of three kinds of model, namely level competition, mutually beneficial cooperation and vertical cooperation. The analysis shows that symbiotic system exists horizontal competition between industry, industry balance scale level is decided by the exogenous supply of resources and industry influence coefficient and has nothing to do with the symbiotic unit inherent industry growth rate. The equilibrium adjustment time of symmetrical mutual symbiosis is short and stable, but non-symmetrical mutual symbiosis is slow and unstable. Based on 1992--2012 years＇ data, the paper calculates Anhui province manufacturing industry and producer service industry symbiosis degree and determine their symbiosis mode category. The study finds at present Anhui province manufacturing industry and producer service industry is in a transformation course from the non-symmetrical mutual symbiosis to symmetric mutual symbiosis.
