Research On The Relationship Between Job And Housing And Its Influencing Factors Of New City Space In The Fringe Of Big City Based On Multi-source Data

As the periphery of the central urban area,the urban fringe has the typical attribute of urban-rural fringe.With the continuous expansion of the city,New city on the edge of big city have gradually formed.It mainly refers to the population gathering space which is used to relieve population,industry,transportation and other functions,has a certain scale,and maintains an appropriate distance and convenient connection with the central urban area.Its main feature is that it has an obvious transformation from non urban space to urban space,and its spatial structure has changed significantly and rapidly under the influence of urban development.As the most direct mapping of urban spatial structure in daily production and life,the relationship between work and residence is related to residents’ residence,employment and commuting.Therefore,in the construction process of New city on the edge of big city,it is easy to have the problem of imbalance of work and residence relationship in varying degrees,which leads to prominent contradictions such as pendulum commuting phenomenon and low land use efficiency.It is important to identify the space distribution of New city and the effective relationship between occupation and residence,which is of great significance to the sustainable development of New city in the future.This is also the origin of this study.With the development of information technology,big data represented by mobile signaling data has the characteristics of fast,accurate and comprehensive.It can obtain the spatial distribution of urban work and residence,the change of urban population density in different periods,the commuting characteristics of work and residence,and provide a new idea for the analysis of the relationship between work and residence.The traditional methods of field investigation,visit and questionnaire can understand the attribute characteristics of individual economy,society and emotion from the micro level.The combination of the above multi-source data provides a basis for the study of the relationship between work and housing and the influencing factors of New city in the fringe of big cities.Taking Wuhan Huashan ecological New city as the empirical research object,supported by the use of multi-source data such as mobile phone signaling data,and according to the research idea of "job housing space identification-job housing relationship characteristic analysis-influencing factor analysis",this paper makes a systematic study on the job housing relationship and influencing factors of Wuhan Huashan ecological New city by comprehensively using quantitative and qualitative research methods such as GIS spatial analysis,correlation analysis and multiple linear regression model.Provide rational decision-making basis for the follow-up sustainable and healthy development of the new city.The specific contents of the study mainly include the following aspects:Firstly,this paper analyzes the connotation of the relationship between work and housing and the typical characteristics of the relationship in the general sense.Secondly,this paper studies the relevant theories of job housing balance,interprets the acquisition and analysis methods of mobile signaling data and other data,and studies the measurement methods of job housing spatial characteristics and job housing commuting,which has accumulated the foundation for further empirical analysis.Thirdly,try to use the big data represented by mobile signaling data and traditional questionnaire data as the basic data source to make an empirical study on Wuhan Huashan ecological New city.The results show that the occupational and residential space of Huashan ecological New city presents the characteristics of large dispersion and small agglomeration of residential space,and the employment space has obvious preference.Based on the measurement index results of the relationship between work and residence,it is found that the total amount of Huashan ecological New city is balanced,but the quality matching is unbalanced.In terms of working,living and commuting,the average commuting distance of Huashan ecological New city is11.31 km,which is far higher than the national standard,and the external commuting ratio shows an upward trend,especially with the East Lake New Technology Development Zone.Fourthly,It is found that environmental factors(road traffic system construction,land function layout,public service facilities and housing supply structure)and individual attribute factors(social attribute,economic factor,institutional factor and emotional factor)affect the working and living relationship of Huashan ecological New city to varying degrees.In terms of environmental factors,the perfection of road system and the coverage of public transport affect the relationship between work and residence in Huashan ecological New city;Improving the land mixing degree can improve the balance of work and housing,and reducing the ratio of residential land will improve the balance of work and housing to a certain extent;There is a significant positive correlation between the density of surrounding commercial facilities and the ratio of employment to housing.The imperfect public service facilities accelerate the lack of supply diversity,which has an impact on the relationship between employment and housing;The difference of residents’ demand and choice ability for residence constitutes the multi group living demand of Huashan ecological New city.In terms of individual attribute factors,the commuting distance of men is often greater than that of women.Compared with the single group,the commuting cost of married group is higher,and the commuting time becomes shorter with the increase of age;The middle and low-income class is more vulnerable to the negative impact of the dislocation of urban living space;The commuting distance of registered residence in non Huashan New city is relatively short.For those who wish to stay in Huashan ecological New city for a long time,a suitable job residence relationship is particularly important.Finally,on this basis,optimize the design of Huashan ecological New city around four aspects: commuter transportation,land layout,public service facilities and housing security,so as to improve the relationship between work and housing in the New city.
