Abstract: The policy of transformation of scientific and technological achievements is an important factor affecting the effect of transformation of scientific and technological achievements, and policy tools have a configuration effect on transformation of scientific and technological achievements. With Roswell's classification of policy tools as reference, the comprehensive policy texts of scientific and technological achievements transformation in 31 provinces, autonomous regions and municipalities in China were coded, and fsQCA was used for analysis, taking policy tools as the condition variable and local technology market contract turnover as the result variable. It is concluded that income reward and infrastructure construction are the core conditions to promote the transformation of scientific and technological achievements. Government procurement, personnel training, financial support and examination and supervision have no significant effect on the transformation of scientific and technological achievements. Infrastructure construction, tax incentives and revenue incentives can be used together to promote the transformation of scientific and technological achievements. Finally, according to the empirical analysis results, it is proposed to strengthen the use of income incentives and infrastructure construction policy tools, pay attention to the use of policy tools combination, and increase the proportion of demand policy tools.
