Abstract: This paper puts forward the TOE integrated analysis framework of the performance improvement path of manufacturing green transformation, and uses fs-QCA method to analyze the cases of manufacturing green transformation in 30 provinces in China. The study found that: (1) From 2010 to 2019, the green transformation performance of China's manufacturing industry showed a good trend of steady increase, and had obvious phased characteristics; (2) The green transformation performance of manufacturing industry is the result of the complex action of multiple conditional variables. There are three driving modes of high green transformation performance, namely, support pull type, competition pull collaborative type and information-based leading type. The technical conditions, especially the information level, play a major role in it, and the support pull type is the most widely distributed; (3) There are two performance driven modes of non high green transformation, namely, pressure damage type and respect and treatment type, in which environmental conditions play a key role, and pressure damage type is the most common; (4) Full government support is an indispensable organizational condition for the green transformation of manufacturing industry. The research broadens the application scope of relevant theories and provides experience for the practice of green transformation of manufacturing industry.
