Research on the Correlation between the Vehicles' Annual Inspection Status and Economic Development

The flow of logistics vehicles is one of the important indicators of local economic development, but it is difficult to reflect the development of people's living standards. By contrast, the data of annual inspection vehicles can reflect the situation of local economy and people's living standards more comprehensively. This paper aims to research the correlation between the vehicles' annual inspection and economic development as well as living standards from multidimensional perspectives. Besides, new methods of studying economy and new perspectives on analyzing data are proposed in this paper. From a time perspective, statistics on the quantity of vehicles inspection and local annual inspection rate. From a spatial point of view, statistics on the inspection status of vehicles in different regions and types. Incorporating the local transportation, policies, people's living standards, economic development status, industrial distribution, etc. The contrastive analysis method, grouping analysis method and predictive analysis method are used to dissect the current situation of urban development. The laws of physics behind the data show that: 1) The annual inspection number and growth trend of vehicles compared with the local GDP and its growth rate show a positive correlation, which explains that the vehicles annual inspection status has a strong correlation with the economic development. 2) Combined with the cardinal number of local annual vehicles inspection and annual inspection rate, comparing with the economic situation of each county and district. Its changing trend presents connection with the local economic development level, which shows that the changing trend partly reflects the local economic development level in recent years and its space for rising. 3) Besides the economic center, the destinations where vehicles markedly flow to also includes the neighboring counties with higher economic level. To some extent, it not only reflects the economic disparities between counties and districts, but also comprehensively reflects the economic interaction between counties and districts. 4) The annual inspection distribution of different types of vehicles differ from all vehicles, each with its own characteristics. On a certain level, it shows the distribution characteristics of economically active areas such as urban chemical industry, population-intensive areas, external trade industry, etc.
