Spatial Agglomeration of High-tech Industries and its Suitability

Prom oting healthy development of high-tech industrial agglomeration,must verify its effectiveness.From the input and output aspects,the article constructs HTCI（high technology industry cluster index）for describing its agglomeration,the result shows the spatial distribution high-tech industry appears the polarization characteristics,the eastern coastal high-tech industry is in high agglomeration state.TFPCH（total factor productivity change）of high-tech industrial increased significantly,in which TE（technological efficiency change）play a major role,and TCs（technological changes）effect is small.Researching the relationship between the agglomeration and TFPCH of the eastern coastal high-tech industry,there is long-run equilibrium between the agglomeration change and the TFPCH,but the short-term equilibrium has been damaged,showing excessive agglomeration.Typical provinces study reveals:in the current development mode,Guangdong,Jiangsus high-tech industrial have shown agglomeration non-economic signs in the short-term,while Shanghai is moderate.
