简介：AbstractSince the coronavirus disease 2019 (COVID-19) pandemic, major innovative-oriented countries have adopted various science and technology innovation (STI) policies to address global public health challenges. Using data from the Organization for Economic Co-operation and Development STI Database, this study analyzed international STI policies in response to the COVID-19 pandemic. The findings revealed that the pandemic has dramatically stimulated the application of STI policies, and there are commonalities and differences in the STI policies of different countries. Meanwhile, COVID-19 has disrupted planning for allocating resources for STIs, leading to duplication and inefficiency. Based on the findings, this study recommends increasing research investment to address the long-term challenges of major infectious diseases, strengthening support for enterprises, promoting data sharing and openness, enhancing the internationalization of scientific research, strengthening scientific consultation and communication, and devoting more policy attention to vulnerable groups.
