With roots in Guangdong Province and Shenzhen, the Research Institute of Tsinghua University in Shenzhen regards the innovation of system and mechanism as its life, and has carried out fruitful exploration in the aspects of investment mechanism, employment mechanism and incentive mechanism. It has explored the transformation mode of scientific and technological achievements with the deep integration of industry, university and research, and created an efficient and three-dimensional incubation system.

After more than 20 years of construction, the Institute has formed a new situation of interactive development of six functional areas, including research and development platform, personnel training, investment incubation, innovation base, science and technology finance, and international cooperation. It has created five "firsts" : the first new scientific research institution; It was the first to put forward the concept and model of "Sibuxiang"; The venture capital company of the first new scientific research institution; The first technology financial platform for new research institutions; The first overseas innovation and entrepreneurship center for a new type of research institution.

In terms of the laboratory construction mechanism, the research Institute explores the simultaneous establishment of "laboratories (or R&D centers) and industrialization companies", taking the market as the key factor for allocating innovation resources, and the assessment of achievements is measured by the market efficiency. In terms of project input mechanism, technical experts and investment and financing experts should participate together, and inventors and responsible persons should take the lead in input; In terms of the employment mechanism, it breaks through the limitation of the establishment of public institutions and has no "iron rice bowl". It attracts high-end innovative talents at home and abroad with equity and market-based salary level. In terms of incentive and regulation mechanism, adhering to the principle that "R&D team shares technology equity, and management team legally holds equity", it has formulated policies such as "Technology Investment Management Norms" and "Regulations on the Management of Part-time High-end Technical Talents".

In the face of the new strategic layout and development opportunities of the state and provinces, the Research Institute of Tsinghua University in Shenzhen is faced with new challenges of second entrepreneurship, and has established the "four combination" concept -- the combination of school and local, the combination of research and development and incubation,
