"Handling every case with high quality and efficiency" is the basic value pursuit of procuratorial organs in fulfilling their duties and handling cases in the new era and new journey. Procuratorial public interest litigation should further improve the accuracy and standardization of case handling to achieve the goal of high-quality and efficient case handling. Currently, due to the wide range of fields and strong professionalism involved in public interest litigation cases, there are problems such as the mismatch between the needs of handling cases and the actual situation. Therefore, effectively achieving the goals of public interest litigation prosecution through integrated performance, comprehensive performance, and proactive performance (hereinafter referred to as the "three types of performance") is a practical path for procuratorial organs to take the initiative to take on responsibilities and achieve high-quality and efficient case handling. To ensure "standardization" through integrated performance of duties. The standardization of case handling is a guarantee for high-quality and efficient performance of duties. We should make good use of the outstanding advantages of integrated public interest litigation, strengthen institutional innovation and cooperation, break down departmental barriers, upper and lower barriers, and regional barriers, effectively optimize the case handling mechanism, unify case handling standards, and improve the standardization level of case handling. One is to improve the horizontal integration litigation linkage mechanism and consolidate the evidence foundation. Strengthen communication with the other three major prosecutors in terms of information dissemination, clue identification, and collaborative supervision through specific mechanisms such as normalized business communication, mutual lead transfer, and cross departmental prosecutor joint meetings. Collaborating with the Criminal Investigation and Prosecutors, we integrate big data and intelligent empowerment to perform our duties, and use combination keywords for search and screening in key areas such as environmental protection, food and medicine, and safety production, in order to improve the efficiency of clue transfer. By intervening in advance, cooperating in investigation and evidence collection, and other means, we can timely fix the facts of public welfare damage, improve the success rate of clues, and enhance the effectiveness of integrated performance. The second is to strengthen the guidance and supervision of vertically integrated case handling, and guide standardized handling. At present, the public interest litigation prosecution is in a critical period of high-quality development, shifting from a high growth rate in the past to prioritizing quality and efficiency. It is necessary to achieve effective internal supervision through integrated performance, and to improve the standardization level of case handling at a higher rate. According to the "Rules for Handling Public Interest Litigation Cases of the People's Procuratorate", according to the needs of handling cases, the superior court may change its jurisdiction through methods such as assigning, submitting, supervising, and leading. The superior court should not only play a demonstrative role in high-quality and efficient case handling, but also deploy special actions based on the actual situation of the jurisdiction, carry out business inspections, urge the jurisdiction court to identify its own advantages, continue to deepen the construction of "one court, one characteristic, one brand", and build a brand matrix of public interest litigation services for high-quality economic and social development. The third is to strengthen cross regional integration and cooperation, providing a institutional foundation for comprehensive and long-term protection. For example, the integrated development of the Yangtze River Delta is a national strategy, which should closely focus on the keywords of integration and high quality, and better play a leading role in exploring, demonstrating, and radiating. The procuratorial organs adhere to the integration of procuratorial cooperation in the demonstration zone, link with the joint signature and cooperation mechanism of multiple procuratorates, expand the scope of policy radiation and mutual recognition areas, and achieve multi-party win-win in collaborative case handling, work docking, resource sharing, and governance integration. To unleash the scale effect of regional cooperation and explore the implementation of cross regional "carbon sequestration" special actions. To unleash the synergistic effect of improving quality and efficiency, vigorously promote data collaboration, and strengthen the integration of digital prosecution. For cross administrative watershed governance, establish a cross provincial "river chief+police chief+prosecutor" mechanism, jointly carry out special investigations and centralized public hearings, and promote the upgrading and efficiency expansion of ecological prosecution.
