In order to promote the renewal and development of the capital city and avoid the "low-speed development trap" in the economy, the government proposed to use "high-tech" industries as the driving force to accelerate the construction of a "high-tech" industrial economic structure and increase investment in industrial innovation, so as to better guide and support overall and long-term development of economic and social. This article uses the SWOT analysis model, based on the actual development of Beijing’s industry, deeply analyzes the advantages, disadvantages, opportunities and challenges of the city’s development of "high-tech" industries, and proposes four aspects of countermeasure, such as improving fiscal and tax incentive policies, improving financing methods, optimizing industrial layout, promoting dual-chain integration. Beijing Municipal Government should speed up a reasonable "high-tech" industrial structure, give full play to the role of "high-tech" industries in "improving quality and efficiency" in Beijing's economic development, and then optimize and enhance the core functions of the capital.

In order to promote China's economy high-quality development, the country has continuously lowered the certification standards for high-tech enterprises. The existing research literature has not yet reached a clear conclusion about the impact of high-tech qualification certification on enterprise innovation performance. This paper uses the Shanghai and Shenzhen A-share listed companies from 2013 to 2018 as a research sample. Through the propensity score matching method, it is found that the implementation of the high-tech enterprise identification policy has an effect on the innovation performance of the enterprise, especially for strategic innovation represented by the number of non-invention patent applications. The sub-sample results show that the identification policy has a more obvious impact on the innovation performance of non-state-owned enterprises, young enterprises and larger enterprises. Finally, based on the results of the research, it is proposed to continuously improve the identification policy, guide enterprises to make substantial innovations, and implement hierarchical tax rates for different types of enterprises to help improve the identification policies for high-tech enterprises.
