The Impact of High-Tech Industrial Agglomeration on Economic Development

— China's economy has shifted from high-speed growth to high-speed development, and is in the crisis of changing development mode to improve the driving force of economic environment change to drive growth. As an important area of China's economic development, the source of economic development and the gathering place of emerging industries, the Pearl River Delta has important reference value for the development of other urban agglomerations. Therefore, based on the Pearl River Delta, the added value of high-tech manufacturing industry in the Pearl River Delta will increase from 461.289 billion yuan in 2013 to 99086 billion yuan in 2020, 2.1 times that of 2013. Based on the analysis of high-tech industry, business focus and relevant theories of economic growth, this paper analyzes the impact of high-tech focus on the mode of economic growth. Second, based on the local economic development in the Pearl River Delta, select the economic distance matrix, and according to the empirical analysis results, establish a field-specific measurement model for the visualization analysis of high-tech industrial agglomeration to guide material agglomeration. In order to better understand the characteristics of high-tech industries in the Pearl River Delta urban agglomeration and the impact mechanism of economic development, and make policy recommendations for urban economic development. Finally, according to the current high-tech industry agglomeration in the Pearl River Delta, the paper puts forward suggestions from four aspects: promoting the development of industrial agglomeration, strengthening the division and cooperation of high-tech industries, implementing the differentiated and orderly talent attraction policy, and guiding the rational flow of government funds, and provides a perfect match for the overflow results of high-tech business integration.
