The Accidental Republic is a concern for all industrialised countries, and China is no exception. To solve this problem, Workers’ Compensation Insurance (WCI) is a perfect option. The redemption of The Accidental Republic can be understood through the development of WCI. However, little attention has been paid to the development of Chinese WCI. Starting from labour insurance regulations promulgated in 1951, this research explores over 70 years of reform and development of Chinese WCI, explicitly dividing reforms into three phases – establishment and implementation, exploration and practice, and adaptation and formation – that aligned with stages of China’s economic development. Further, the insurance fund performance in the last decade is evaluated by Data envelopment analysis and Malmquist (DEA-Malmquist), through the static and dynamic results, yielding generally average results. Subsequently, five major problems of WCI are identified and discussed and five suggestions offered drawing on international comparison and the national situation. Lastly, the accidental and inevitable aspects of China’s WCI system during the redemption of The Accidental Republic are summarised.
