Empirical study on the relationship between the spatial agglomeration index and agglomeration efficiency in the textile industry

Taking the textile industry as an example, with the help of a series of input-output indicator, this paper calculates and analyses the agglomeration trend and regional distribution of the overall Chinese textile industry, conducts the Stewart Granger causality test on the relationship between spatial agglomeration degree and agglomeration profits of the textile industries, and discovers the balanced relationship and bi-directional causality relationship between spatial agglomeration level and agglomeration profits of the whole textile industries. But from the perspective of regional analysis, some areas with higher agglomeration level has the inversion phenomenon that the cost-benefit indicator is lower than the national average, and the trends of excessive agglomeration, production factors´ congestion and decreased profits can be proved from more intuitional scatter diagram. Research findings provide theoretical support on how to guide the interregional flow of production factors scientifically, how to achieve industrial gradient shift, how to optimize the resources allocation.
