In 2018，the listed companies in zhongguancun showed great fluctuations in market performance due to the influence of macro economy，despite the overall stable development of their business conditions.

The operating income and net profit of continuously operating enterprises have both increased and the profitability has improved；Moderate solvency，low financial risk；Innovation input and output are both improved，and the international layout of patents is further improved. Faced with the above situation，this report proposes that：the interaction between listed companies in Zhongguancun and investors in the capital market should be promoted to guide the market to pay attention to the development of high-tech enterprises；Beijing should attach importance to tax and fee reduction of key industries to help form the regional aggregation effect of industrial chain；Broaden the financing channels for private enterprises and solve the financing difficulties of private listed companies in Zhongguancun.
