竞争态势下区域生态物流科技资源配置协同演化模型构建研究

Research on a Co-evolution Model Construction of the Scientific and Technological Resource Allocation of Regional Ecological Logistics under Competitive Situation

优化行业科技资源配置是推动物流业科技创新的关键,是其走现代化转型的必经之路。文章以区域物流生态系统作为研究对象,将科技资源配置效率作为外生变量来缓解种群内竞争强度,改进了传统的Lotka-Volterra模型。借助该模型推导了物流种群间竞争关系的四种约束条件以及产生的对应竞争态势,以不同物流种群竞争共存为目标,根据推导的约束条件,通过MATLAB软件进行了仿真计算。结果表明,在满足约束条件的基础上,物流种群间竞争的共存会产生两种不同结果。据此,建议政府可以将科技资源配置效率作为抓手来进一步推动“赛马”机制在生态物流行业中的应用。

Optimizing the allocation of scientific and technological resources in the logistics industry is a key to promoting its innovation and also a necessary way of its modernization transformation.In this paper,the traditional Lotka-Volterra model is improved by taking the allocation efficiency of scientific and technological resources as an exogenous variable to alleviate the intensity of category competition.With the help of this model,the four constraints of the competitive relationship between logistics populations and the corresponding competitive situation are deduced.Aiming at the competitive coexistence of different logistics populations,the simulation calculation is carried out by MATLAB software according to the deduced constraints.The results show that,on the basis of meeting the constraints,the coexistence of competition among logistics populations will produce two different results.Therefore,it is suggested that the government can take the allocation efficiency of scientific and technological resources as a means to further advance the application of"horse racing"mechanism in the ecological logistics industry.
