Industrial Agglomeration of High Technology in Yangtze River Delta City Cluster Based on Knowledge Spillover Spatial Effect Study

The Yangtze River Delta (YRD) region has been a strong innovation capability and good economic development environment. This paper will focus on the spatial effects of high-tech industrial agglomeration in based knowledge spillover theory, with regional city cluster as research object. begins review relevant literature spillover, industry relationship between science technology growth. On this basis, we measure degree 27 urban areas using locational entropy method analyze current situation Delta. It is found that most agglomerations are not randomly distributed first third quadrants, indicating they have considerable correlation, then countermeasure suggestions given.
