Abstract This paper collects patent applications and related data of innovation output of high-tech industries in 30 provinces and cities in mainland China from 2000 to 2018,and used ArcGIS spatial analysis tool to conduct a visual analysis of their spatial agglomeration characteristics.Using QAP method in network analysis to analyze its key influencing factors finding:①the important feature of spatial agglomeration of high and new technology industry innovation output is regional imbalance,"the Matthew effect" is obvious;②the strong-strong correlation is mainly concentrated in the southeast coastal and parts of the central region,the weak-weak correlation is mainly concentrated in the northern and southwest regions,and the weak-strong and strong-weak correlation is mainly concentrated in a few northern,central and southern regions;③among the factors influencing the spatial agglomeration and correlation of high-tech industry innovation output,in input variables,the R&D expenditure is significantly positive correlation,and the R&D personnel is significantly negative correlation.in spillover variables,the industry-university-research cooperation is not significantly positively correlation,the industrial agglomeration and geographical distance are significantly positively correlation,FDI is significantly negatively correlation.
