基于L-V模型的重庆两江新区生产性服务业与现代制造业协同发展实证研究

Empirical Research on Collaborative Development of Producer Service Industry and Modern Manufacturing in Chongqing Liangjiang New Area Based on L-V Model

为探索生产性服务业与现代制造业之间的竞争与协同互动发展的内在机制,借鉴生物学共生理论,采用LV模型分析、非线性最小二乘、调查访谈等方法分析了两产业之间的协同发展机制,以两江新区为实证分析估算了L-V模型及离散转化模型的相关参数值,并对模型的均衡点和稳定性予以分析并得到均衡点的稳定性特征值;结果表明L-V模型能较好地契合生产性服务业和现代制造业之间的协同发展机制研究,两产业之间存在互利共生、互为支撑,实现共同升级与发展.

In order to explore the intrinsic mechanism of competition and interaction between producer service industry and modern manufacturing. The L-V model analysis, nonlinear least square method, investigation method, and documentary combing, etc., have been adopted in this paper by learning from biological symbiosis theory. By conducting an empirical analysis of Liangjiang New Area, it estimates the relevant parameters of L-V model and discrete transformation model, gives analyses on the model s balance point and stability and gets the steady featuring values for balance points. Research results show that L-V model can well fit in with the research on coordinated development mechanism between producer service and modern manufacturing which see mutualism and complementary support and realize mutual upgrading and development.
