Chen Minhua longs to fill the vacancy of drug crystals in China and take the lead in the international drug crystal research. Chen Minhua introduced that government service is an integral part to his growth. "Since it was settled down, Suzhou public sector organized several investment and financing activities and offered training and services in various aspects like the mode of financing, finance docking and enterprise strategic investment, which laid a solid foundation for Crystal Pharmatech's capital expansion", said by Chen Minhua.


To help high-level talents solve financial difficulty, Suzhou lays stress on the docking of science & technology and finance. The person in charge of the Municipal Science and Technology Bureau said that Suzhou guides and integrates social capital for equity investment of hi-tech enterprises at the start-up stage via the guiding funds set up by the government and follow-up investment, etc, thus evolving the venture capital investment cluster based on Shahu Equity Investment Center. After the national "Thousand Talents Plan" venture capital investment center was set up, pioneering talents and venture capital are further converging here. As of the end of 2013, there are 270 effective organizations engaged in various venture capital investment in Suzhou that manage the funds in excess of 88 billion Yuan. 30 million Yuan will be appropriated from the municipal science and technology fund budget for the newly established FOF of Angel Investment this year, so as to take avail of social capital for the development of small and medium-sized hi-tech enterprises.


Meanwhile, Suzhou sets up the special compensation fund against credit risks and offers "Kedaitong" with "low threshold and low interest rate", so as to solve financial difficulty of small and medium-sized hi-tech enterprises and create favorable financing environment for the pioneering work of talents and corporate development. At present, the fund of credit risk pool has reached 500 million Yuan and "Kedaitong" loans of 8.52 billion Yuan have been granted for 1023 small and medium-sized hi-tech enterprises. Particularly, 120 pioneering enterprises that feature independent intellectual property, high content of technology and light assets were backed up with 1.314 billion Yuan, the special risk compensation fund of "Kedaitong", thus vigorously supporting innovation and pioneering work of leading talents in the science and technology community in Suzhou.
