Job-Housing Spatial Relationship Evolution in Guangzhou Analysis, Reflection and Coping Strategies

The residence and employment locations are significant components of urban space while the job-housing spatial relationship becomes a crucial object of urban spatial organization research. By analyzing the collected data of 64 traffic central regions in the city of Guangzhou, it can be concluded that the job-housing balance ratio is related to traffic mobility. The detailed relationship can be summarized into following points: the high job-housing balance ratio can reduce the proportion of trip and alleviate traffic congestion; there is an "inverted U" type correlation between the job-housing ratio and job-housing balance ratio, which proves a reasonable job-housing balance ratio can often be achieved when the job-housing ratio remains between 0.55 and 0.60; the intensity of trip is highly correlated with population density and employment density, while the impact of employment density on it is greater than the impact of population density. Therefore, combining with the characteristics of job-housing distribution in the city of Guangzhou, this paper reflects on several problems existing in the expansion of Guangzhou's job-housing space, and then based on the correlation between the relevant factors like job-housing ratio, job-housing balance ratio and traffic mobility, proposes some feasible suggestions including corridor balance, employment decentralization and reasonable control of the job-housing ratio in the new planning area and so on.
