On September 29, 2016, the Supreme People's Procuratorate formulated the "13th Five-Year Plan for Scientific and Technological Strengthening of Procuratorial Work," establishing the overall goal of a five-dimensional integrated "sense, transmit, know, use, manage" smart procuratorial application system, and clarifying the procuratorial big data construction task of "gradually building a big data support environment, gradually carrying out big data applications, and laying the foundation for 'smart procuratorial'." In June 2017, the Supreme People's Procuratorate issued the "Procuratorial Big Data Action Guide (2017-2020)," clarifying the future development direction, goals, and tasks of "smart procuratorial," strengthening overall planning, and actively encouraging and orderly guiding local authorities to explore and innovate in big data construction and application, avoiding low-level repeated construction. The provincial procuratorate, combining the requirements of the Supreme Procuratorate and its own needs, needs to fully grasp the favorable opportunity of the new scientific and technological revolution wave, take data resources as the core, take new-generation information technology as the engine, and take various data applications including procuratorial business decision support as the basis, to promote the improvement of the procuratorate's legal supervision capability and law enforcement credibility, improve the procuratorate's management efficiency, improve the team's capability and quality, and realize the strategic transformation from technology serving to technology leading procuratorial work.
