【摘要】 我国的资源型城市在发展中虽然取得了重要的成就,但这类资源开采期限因资源储量限制而必然会结束,随着资源不断耗竭,资源型企业的转型成为研究资源型城市经济发展的重要内容。伴随资源开发、生产成长起来的资源型城市,由于人口增长及人民生活水平的不断提高,对城市生产和生活物资的需求是逐渐增大的,如何将资源型企业已有的物流系统与其所在的资源型城市物流系统相耦合,打破二者之间的不合理条块分割,将两个系统有机的结合,使耦合系统在结构上、功能上进行统一、协调发展,既是资源型企业产业转型的一个方向,也是减少区域物流资源浪费,避免重复建设的重要措施。本论文的主要内容的如下:(1)从耦合和系统的角度,提出了资源型城企物流耦合系统的概念,说明了建立资源型城企物流耦合系统的科学性、合理性和必要性。(2)使用自组织和自组织演化理论对资源型城企物流耦合系统进行机理分析。对自组织理论群中的耗散结构理论、协同学理论等理论进行了概括和归纳,并应用自组织演化理论对资源型城企物流耦合系统的发展轨迹进行分析,找出资源型城企物流耦合系统的运行特征和影响因素,构造了布鲁塞尔模型和熵流模型来分析耦合系统的非平衡演化情况及演化过程和规律。(3)采用系统动力学原理对资源型企业物流系统与资源型城市物流系统相耦合的主要要素和指标进行分析,确定了资源型城企物流耦合系统的系统动力学建模程序,通过研究耦合系统内各主要因素之间和子系统之间的关联关系,同时借助一些辅助模型,建立了资源型城企物流耦合系统的系统动力学模型,并进行了模型的计算机编程、调试和检验。(4)建立了资源型城企物流耦合系统耦合程度评价的人工神经网络模型,提出资源型城企物流耦合系统耦合度的概念,依据协同理论的序参量特征,确定耦合系统内四个子系统的序参量和耦合系统耦合度的评价指标体系,并给出理论依据。对系统的协调程度从耦合系统的整体角度和子系统之间分别建立评价模型,并根据不同情况编写程序、调整和检验。(5)将所建立的资源型城企物流耦合系统的系统动力学模型及耦合程度评价的人工神经网络模型应用于山东省著名的资源型企业兖州矿业集团及其所在的资源型城市济宁市,进行实证分析,通过模拟与评价的结果对制约系统协调发展的因素进行分析,不断的调整系统的主要因素和设计不同的模式对耦合系统进行改善,并对未来耦合系统的发展进行预测,针对可能出现的问题,提出相应对策及建议。(6)从我国资源型企业及资源型城市发展的实际出发,对资源型企业物流与资源型城市物流的协调发展进行整体规划,从资源型城市功能的定位、资源型企业转型的方向上进行全面的流程设计,按照资源型城企物流耦合系统功能的总体发展规划步骤,研究建立资源型城市的资源开发补偿机制和衰退产业援助机制及创新机制来促进二者的协调发展。论文的创新点主要体现在以下几个方面:(1)系统研究了资源型城企物流耦合系统的演化理论和特征,构造了布鲁塞尔模型揭示耦合系统演化的规律,建立了熵流模型对耦合系统进行演化过程中的涨落分析。(2)运用系统动力学模型对资源型城企物流耦合系统进行描述,将资源型城市物流需求系统、资源型城市物流供应系统、资源型企业物流需求系统、资源型企业物流供应系统作为一个有机整体来研究子系统之间及其要素之间的相互关系,利用系统动力学的DYNAMO语言,通过Vensim软件实现模拟和仿真。(3)运用人工神经网络方法构造出耦合系统的评价模型,采用综合集成的方法,首次提出资源型城企物流耦合系统耦合度的概念,对于系统的协调程度从耦合系统的整体角度和子系统之间分别进行评价,并给出资源型城企物流耦合系统耦合度的计算方法和判断系统耦合度的程序。应用Mtalab软件对系统的评价进行编写程序、调整和检验。(4)通过济宁市和兖州矿业集团的实际情况对上述方法进行实证分析。对资源型企业物流与资源型城市物流的协调发展进行整体规划。从二者发展的定位、模式及方向上进行全面的流程设计,构筑了资源型城市的物流系统和资源型企业转型物流相结合的系统分析方法和理论模式。

【Abstract】 Although the resource-based cities in China have made great achievements in economic development, the cities which take resource-based enterprises as the main resource-producing resources will have to face resource exhaustion, then cause development obstacle of resource-based cities.The transformation of the resource-exhausted enterprises therefore become an important part of the research of resource-based cities. The resource-based cities, which grew up with the development and production, with the affect of population growth and the improvement of people’s living standards, the demand of town production and living materials is gradually increasing. How to couple resource-based enterprises logistics system with the city’s existing logistics system, break unreasonable fragmentation within the system, couple two systems effectively, so that coupling system can develop in the structure and function unitedly and coordinately, is not only a direction of transformation of the resource-based enterprises, but also an important measure which can reduce the waste of regional logistical resources and avoid redundant construction.The main content of this dissertation is as follows:(1) From the perspective of coupling and system, this dissertation puts forward the concept of resource-based city-enterprise logistics coupling system, explains the issue about establishment of Resource-based City-enterprise logistics coupling system and the combination of resource-based cities and enterprises is scientific, reasonable and necessary.(2) The author made use of self-organization and self-organization evolution theory to do a mechanism analysis of resource-based city-enterprise logistics coupling system. After generalizing the self-organization theory, dissipative structure theory, synergy theory and other theories, the author analyzed the development trace of resource-based city- enterprise logistics coupling system by self-organization evolution theory, found out the operating characteristics and the main factors, constructed Brussels model to analyze the station of the non-equilibrium evolution of the coupling system, including analyzed its self-organization characteristics and evolution motivation, evolution process and discipline of the coupling system.(3) The author adopted system dynamics to research the elements and description target of resource-based city-enterprise logistics coupling system. Through studies of the link of the main factors of the system, the author made sure the method establishment and the modeling program of the SD model of resource-based city-enterprise logistics coupling system, established the system model with the combination of the assistant model, and realized the various models of computer programming, debugging and testing.(4) The author build the ANN model of the coupling degree evaluation of the coupling system, put forward the concept of the coupling degree of resource-based city-enterprises logistics coupling system. Based on the theory of order parameter in synergies theory, the author determined the order parameter of coupling system, the extent of the index system and pr(?)vided theoretical basis for the evaluation of the coupling degree, builded evaluation models for the degree of coordination of the coupling system from the perspective of the overall coordination and among subsystems, and programed, debugged and testified under different conditions.(5)The author applyed the SD model and ANN model to the famous resource-based enterprise Yanzhou Mining Group in Shandong Province and the Jining City, to do the empirical analysis, simulation and evaluation. Analyzed the factors that hinder the coordinated development of system, constantly adjusted the factors and designes different models to evaluate the coupling system, predicted future development of coupling system, appropriate countermeasures and suggestions aimed at the problems that might arise.(6) According to the requirements of the coupling system and the reality of development of China’s resource-based cities and enterprises, the author did a flow design from the location of the function of resource-based cities, from the direction of the resource-based enterprises transition and from the perspective of coordinated development between resource-based enterprises logistics and city logistics, we should schedule the planning steps for overall development of the logistics function, establish resource development compensation mechanism and aid dying industries mechanism and innovative mechanisms to promote coordinate development of resource-based enterprise logistics and city logistics.The main innovations of the dissertation are in the following areas:(1)Form research the evolution theory and characteristics, the dissertation proposed resource-based city-enterprise logistics coupling system systematically, created Brussels model innovatively to reveal the discipline of evolution of city-enterprise resource-based logistics coupling system and build an entropy model to do a fluctuation analysis of the evolution process of coupling system.(2) The author made use of System Dynamics Model to describe resource-based city-enterprise logistics coupling system, took the resource-based cities logistics demand system, resource-based cities logistics supply system, resource-based enterprises demand logistics system and resource-based enterprise logistics supply system as a whole to study the relationship between the elements and the subsystems. By DYNAMO language of the system dynamics, we use software VENSIM to realize simulation and emulation.(3) The author constructed evaluation model of coupling system by Artificial Neural Network method, made use of integrated methods, put forward the concept of coupling degree of resource-based city-enterprises logistics coupling system, evaluated the degree of coordination of the coupling system from the perspective of the overall coordination and subsystems, and provided the calculation method about the coupling degree of resource-based city-enterprise logistics coupling system and the program of judgment about the coupling degree,by the system evaluation of Matlab to program, adjust and verify.(4) The author took the actual situation of Jining City and Yanzhou Mining Group for empirical analysis of the above method.For overall planning of the coordinated development of the resource-based enterprises logistics and city logistics, the author designed the flow of coordinated development of the resource-based enterprises logistics and city logistics from both of position, mode and direction, and provided systemic analysis mothed and academic pattern of coordinate development of the resource-based enterprise logistics and city logistics.
