The Chinese-style technological innovation is not only the primary driving force for promoting high-quality develop-ment in China,but also a core element for realizing the Chinese-style modernization.Sino-foreign joint ventures,as the im-portant outcome of China's rational utilization of foreign investment and deepening of Reform and Opening-up,play a significant role in the Chinese-style technological innovation.By systematically combing the specific contextual background of technology innovation in Sino-foreign joint ventures within the context of China's modernization development and the evolution logic of Chi-na's macro policies,this paper explored the characteristics,patterns,and evolutionary path of their technological innovation.The study showed that:(1)The technological innovation of Sino-foreign joint ventures has gone through three stages:the embryonic stage,i.e."market for technology"stage(1978-late 20th century),the exploration stage,i.e.the technology in-troduction,assimilation,absorption and re-innovation stage(late20th century-2017),and the development stage,i.e.the independent technology innovation stage(2017-present).Significant changes have occurred in the innovation patterns,domi-nance of key and core technologies,and the strength of technological innovation capabilities in each stage;(2)The technological innovation of Sino-foreign joint ventures has experienced a spiral upward trajectory characterized by progress,twists and cycles;(3)The dynamic alignment between the reality of technological innovation and the evolution logic of macro policies has driven the transition of technological innovation stages in Sino-foreign joint ventures,and eventually paving a Chinese-style techno-logical innovation path that is different from such countries as the United States,Japan,and South Korea.This study will provide a reference for understanding the intrinsic logic of dynamic evolution of Chinese-style technological innovation,an insight for the development direction of Chinese-style innovation theory research,and will be of great signifi-cance for an in-depth understanding of China's high-quality development and Chinese path to modernization.
