| The competition in the field of innovation in major countries in the world is showing an increasingly fierce trend,especially in the field of high-tech industries.Faced with the current increasingly complex international environment,China has elevated innovation to the level of the soul of a nation’s development,and hopes to achieve the great rejuvenation of the Chinese nation through technological innovation.As the political,economic,and cultural center of China,Beijing has leading universities,scientific research institutes,technical service institutions,and a large number of high-tech enterprises.It is promoting Beijing to become a technological innovation center with global influence.However,innovation activities in a region do not arise out of thin air.The construction of an innovation center in Beijing requires scientific management decisions from an objective perspective of the development trend of enterprises.Looking at the "three cities and one district"composed of Zhongguancun Science City,Future Science City,Huairou Science City and Beijing Economic and Technological Development Zone in Beijing,the regional economic development is uneven,and it is urgent for managers to formulate different technological innovations.Policies to promote the formation of highly competitive innovation clusters in the above-mentioned regions and promote the coordinated development of technological innovation.This article uses Baidu map POI points of interest data based on companies that have passed high-tech recognition in Beijing from 2015 to 2018,combined with industrial and commercial enterprise registration information and data on the number of patent applications for enterprises,and uses the Beijing area as the research object to analyze its regional characteristics and space The evolution of the pattern.Based on the analysis methods of standard deviation ellipse and kernel density estimation,this paper observes that the overall layout of Beijing’s high-tech enterprises is concentrated in the center and spread outward,and the distribution pattern develops in the northeast-southwest direction.Through kernel density estimation,it is observed that the concentration of high-tech enterprises in the "three cities and one district" composed of Zhongguancun Science City,Future Science City,Huairou Science City and Beijing Economic and Technological Development Zone is different.The two areas of Xueyuan Road and Xierqi in Haidian District,where the Zhongguancun Science City is located,have formed a cluster of high-tech enterprises.The above two areas are only a few kilometers apart in space.The proximity and convenient traffic conditions make them show a trend of interconnection.The agglomeration of high-tech enterprises in the Beijing Economic and Technological Development Zone is expanding year by year,but the trend of agglomeration in the future Science City and Huairou Science City is not yet obvious.According to Porter’s cluster theory and the research results of related scholars,it shows that innovation clusters have a significant effect in leading technological innovation.The construction process of Beijing’s science and technology innovation center needs to refer to the innovation cluster theory as a guide.High-tech enterprises are an important part of the core elements of innovation clusters,and their agglomeration plays a vital role in the research of innovation clusters.The last chapter of this article hopes to provide references for Beijing’s construction of a national science and technology innovation center by studying the evolution of high-tech enterprises in Beijing’s "three cities and one district" in terms of spatial agglomeration,combining innovation cluster theory and case data. |
