摘　　要：在影响企业布局的因子中,首要的就是运费。因此交通运输成本是影响企业布局与产业规划的重要因素。根据微观经济学、工业区位论、新经济地理学中有关交通运输成本和企业选址的相关理论,从道路的角度分析了影响企业交通运输费用和影响区域运输网络效率的诸多因素。结合实际道路情况,针对现有复杂的交通运输网络状况,将现代网络技术和计算机算法理论应用到区域内空间经济活动分析中,建立模型,并针对模型进行理论分析和数据验证,使用Matlab程序语言,采用Dijkstra算法,求解企业布局和产业规划的最优路径;在此基础上,应用运费成本空间参数,引入可行路径的2个判断条件,改进求解最优路径的算法,得出企业布局和产业扩散的潜在可行路径,用以反映并模拟区域中特定空间经济活动沿着大致方向多路并行的现象。这一理论方法对于企业布局、选址和产业规划具有现实指导意义,在企业布局方面,可充分利用最优路径和潜在的可行路径,优化产业布局。在企业选址方面,可围绕最优路径与潜在可行路径,增加企业选址和布局的可能地点。In factors influencing enterprise distribution,the first is freight.Therefore,transportation cost has become important factor influencing enterprise distribution and industry planning.According to the theory about transportation cost and company location in microeconomics,location theory of industry and new economic geography,several factors has been analyzed to influence enterprise transportation cost and efficiency of regional transport networks from the perspective of the road.Based on the actual road conditions,modern network technology and theory of computer algorithm has been applied in spatial analysis of regional spatial economic activity for the existing complex transportation network status.A model has been constituted and theoretical analysis and data validation has progressed for this model. Matlab programming language and Dijkstra algorithm has been used to solve the optimal path of enterprise distribution and industry planning. On this basis,this algorithm has been improved by applying freight cost space parameter and introducing two judgement conditions to obtain several potential available paths in enterprise distribution and industry planning and reflect and simulate the phenomena that regional particular spatial economic activity has been multi-channel parallel along the general direction.This theoretical approach has practical significance for enterprise distribution,company location and industry planning.In the case of enterprise distribution,it has been full use of the optimal path and potential available path to optimize industrial distribution.In the case of company location,it has been done to increase available place of company location and layout around the optimal path and potential available path.
