The Feature Analysis on the Dynamic Developments of Chinese School Sports Fields—The Data Mining Perspective Based on the Fifth and Sixth Census of Nationwide Sports Fields

Using the data from the fifth and sixth census of nationwide sports fields, in virtue of Exploratory Spatial Data Analysis (ESDA) , the author, respectively form nationwide and provincial perspectives, probes into the dynamic development features of Chinese school sports fields. The result shows that 1) The national overall features manifest that the developments of quantity and floor spaces (absolute amounts) of school sports fields are relatively slow, while the specific values of per capita quantity and per capita floor space (relative amounts) are still notably higher than national overall level;fiscal appropriation and units' self-financing are the chief capital sources, and the proportion of fiscal appropriation has an increasing tendency;the situations on occupation, diversion, and deprecation of sports fields in middle and primary schools is quite severe, while the newconstructed or rebuild sports fields attach more importance in intensive land-use (three-dimension) .2) Provincial overall spatial features manifest that there is a phenomenon of spatial agglomeration upon the development level, development proportion, and opening degree of provincial school sports fields, while the agglomeration degree tends to recede. 3) The features of provincial local space manifest that: in the development level, the provinces in northeastern and northwestern regions lag behind relatively in absolute amounts;while the backward regions in relative amounts mainly concentrate in provincial areas of Sichuan, Shaanxi, Shanxi, Shandong, Henan, Hebei, Bejing, and the agglomeration effect are still enhancing;there is a negative correlation between thedevelopment proportion of provincial school sports fields and local economic development level, that is to say, in the provinces with more backward economic development, their school sports fields take a larger proportion, vice versa;in the overall opening degree, the non- open degree of western provincial school sports fields is higher than eastern areas, and the non-open degree in provinces in North China, Northeast is higher than Middle, East China, South China. In allusion to above- mentioned features, the author would like to propose following suggestions: unequivocally differentiate development priorities between colleges & universities and middle & primary schools in the developments of school sports fields in future;positively broaden the capital sources for constructions;change the situation of immoderate reliance on fiscal appropriation;pay attention to regional differences and adjust the measure to local conditions for development of school sports fields.
