Since its pilot implementation in 2015 and formal implementation nationwide in 2017，the procuratorial public interest litigation has been developing fast in China，with the number of cases growing rapidly，and “full coverage” has been achieved in the public interest litigation handling of cases in the procuratorial system. Remarkable results have been achieved in the procuratorial public interest litigation in such four areas as ecological environment and resource protection，food，and drug safety，state-owned property protection，and state-owned land use right transfer. As a system with distinctive Chinese characteristics，procuratorial public interest litigation has promoted institutional innovation in the implementation of cross-administrative jurisdiction mechanism，giving play to the supervision role of procuratorial suggestions in pretrial procedure and exploring the deep integration of modern technology and procuratorial public interest litigation. At present，there are still some problems in procuratorial public interest litigation，such as the unclear investigation and evidence collection power of procuratorial organs，the urgent need to improve the punitive compensation litigation rules of food and drug safety procuratorial public interest litigation，and the need to improve the coordination and guarantee mechanism. Moreover，the overall quantity and quality of cases need to be further improved. It is imperative to further broaden the scope of procuratorial public interest litigation.
