| 摘 要： | 在不改变目前城市结构的前提下．通过模拟居民的居住与就业区位的最优组合获取理论上的最小通勤．过剩通勤是实际通勤成本与最小通勤成本之间的差值．它反映了城市通勤效率和潜力。利用线性规划函数，以广州市为例．利用2001年和2005年家庭调查问卷数据，计算两年的过剩通勤分别为58．41％和44．74％．这部分通勤是可通过优化居住与就业的区位组合而理论上可节约的。过剩通勤与家庭社会经济特征有关，尤其与家庭收入、户籍类型、住房产权和类型等密切相关．家庭结构分化和收入分化是产生过剩通勤的重要原因。除受模型假设产生的误差影响外．过剩通勤的产生还受社会经济体制改革、城市规划与建设及个人的居住与就业偏好等因素的影响：住房、国企和土地等相关制度的改革导致城市居住与就业空间重组、城市规划较少关注小区域范围内居住与就业的平衡、个人的择居和择业偏好的变化．这些因素相互影响、相互作用．共同对过剩通勤的产生和扩大产生重要影响。 |

| Abstract: | Excess commuting which reflects the efficiency of urban commuting and the potential commuting which could be saved, means the disparity between actual commuting and minimum commuting calculated by simulating residential and workplace location choice without changing the urban structure.Linear programming optimization function is adopted to calculate excess commuting of all households and subgroups divided by household structure, housing types and job types of the head and so on.The analysis shows that about 58.41% and 44.74% of the commuting are excess in 2001 and 2005 respectively which could be saved through optimization reorganization of residential and workplace location, which means that the efficiency of commuting and spatial organization of residence and workplace in Guangzhou are very low.Excess commuting has strong relationship with socio-economic characteristics and housing types of households, especially with households' income, types of Hukou (registered residence of a household), housing tenure and types, and occupation of the head.The division of household structure and income are important factors for excess commuting.The simulation of the impacts of residential and employment suburbanization shows that both residential and employment suburbanization increases the minimum commuting.Besides the errors brought by the assumptions of minimum commuting calculation models, the socio-economic systems reform, urban planning and constructions and personal residential and employment preference have great impacts on excess commuting.The reformation of related systems including housing, state owned enterprise (SOE) and land since 1978 has led to spatial reorganization of residence and workplace location in large scale, urban planning policies pay little attention to regional job-housing balance, personal residential and employment preference has great changed, all those factors interacting mutually have major impact on the production and expansion of excess commuting. |
