中文摘要：

本文应用共生理论分析城市群物流与经济共生系统，包括共生单元、共生环境、共生模式，并构建了城市群物流与经济共生系统的结构概念模型。基于城市群物流与经济共生系统分析，运用L—V模型理论，建立了城市群物流与经济共生L—V模型，包括城市群物流与经济偏利共生模型与互惠共生模型。基于模型稳定均衡点条件分析结果，建议增强物流与经济共生单元的共生能力；提升共生系统的共生界面，如优化城市物流基础设施、制定物流服务标准体系；优化共生系统共生环境，如政治、市场、科技和人才等环境；促进城市群物流与经济共生发展。

英文摘要：

This paper analyses city group logistics and economy symbiotic system with symbiosis theory, including symbiosis unit, symbiosis environment and symbiosis model. At the same time, the structure conceptual model of city group logistics and economy symbiotic system has been built. Based on the analysis of city group logistics and economy symbiotic system, the symbiosis L-V model of city group logistics and economy has been established using the theory of L-V model, which contains partial symbiosis model and reciprocal symbiosis model. Finally, this paper puts forward some suggestions about the symbiosis evolution of city group logistics and economy on the basis of the analysis results of the models＇ stable equilibrium conditions. The countermeasures and suggestions include increasing the symbiotic ability of logistics and economy symbiosis unit; enhancing the symbiotic system＇s symbiotic interface, for example, improving city group＇s logistics infrastructure conditions, formulating a system of logistics service standard, etc; optimizing the symbiotic environment of symbiotic system, such as politics environment, market environment, technology environment, culture environment, etc.
