The invention provides a method for measuring urban group economic space connection strength. The method comprises the steps of acquiring an object name in an excel format and economic population data; obtaining the spatial research range and the traffic network data of the city, and performing spatial weighted assignment on the sample points; performing weighted calculation on the shortest traveltime based on the OD cost matrix; calculating urban group space connection strength according to the revised gravity model; and exporting the city contact strength visualization chart and the contactstrength value table. According to the method, spatial distance measurement in a traditional gravity model measurement method is corrected into travel time; carrying out comprehensive weighted analysis on the travel time by combining economic data; and data acquisition, analysis and calculation steps of urban travel time are integrated. Users only need to automatically generate urban economic space connection analysis results according to existing urban economic and social data, and the timeliness and efficiency of urban group space connection strength measurement are improved.
Description
technical field [0001] The invention relates to the field of data processing, in particular to a method for measuring the economic spatial connection strength of urban agglomerations. Background technique [0002] At present, foreign academic circles have broken through the limitations of simple static description and theoretical qualitative analysis in the study of spatial connection, and paid more attention to the application of quantitative model of connection. Domestic research on regional spatial connections gradually emerged after the 1990s. The research content focuses on interregional connections, the focus of research is on the spatial connections between cities and their regions or larger areas, and the research on spatial transportation connections is more important. [0003] The traditional evaluation method of measuring the spatial connection strength of urban agglomeration by using spatial distance connection lacks attention to the data of basic transportation ...
