Measuring the spatial concentration in China's manufacturing:A multi-elliptical model
The extent of spatial concentration of manufacturing reflects the productivity and regional process of a country,resting upon its geography,administrative division,firm location,industrial concentration as well as regional industrial policy.To show the effects of multiple factors underlying spatial concentration,this art-icle,using the standard deviational ellipse,proposes a multi-elliptic method of spatial concentration with refer-ence to two-dimensional continuous geographical space,administrative division,and firm location.Using data on nearly 32 million of manufacturing firms in China,the article measures the extent of spatial concentration and its directions of manufacturing,with the territorial space and prefecture-level administrative divisions as the benchmark.The results showed that,compared with China's territorial space,the degree of spatial concen-tration is 0.71 for the locations,and 0.70 for the employment distribution of manufacturing firms;with refer-ence to the locational and population distributions of administrative regions,the degree of spatial concentration falls to 0.54 and 0.32,respectively for the employment distribution,and to 0.55 and 0.33 for the locations,of China's manufacturing firms.In comparison with firm locations,the employment distribution of manufactur-ing firms appears weakly dispersed.The main directions of spatial concentration are also identified accord-ingly.It shows that our multi-elliptic approach can reveal the complexity of spatial concentration in manufac-turing,with concentration measurement added to the understanding of spatial agglomeration of manufacturing firms.
