Rule of Law Index Innovation Project Group，Institute of Law，Chinese Academy of Social Sciences，was entrusted by the Supreme People’s Court to conduct the third-party assessment of the construction of the intelligent trials of Chinese courts from 2018 to 2022. Over the last five years，the informatization construction of Chinese courts shifted from Version 3.0 which was data-centric to Version 4.0 with knowledge as the center，intelligent courts as the core and judicial data middle office as the engine. The intelligent trial ability of Chinese courts kept increasing. During the last five years，the intelligent trial of Chinese courts gradually transferred from the electronic tools，including technological courts，remote videos and electronic seal，to the information technology applications，including 5G，Internet trial，big data application，blockchain and AI-assisted trial. The trial and adjudication of Chinese courts became more convenient and showed such characteristics as being networked，electronic，automatic，intelligent and public. A judge’s trial and adjudication increasingly depended on the latest results of intelligent trial. But the assessment work reveals that the intelligent trial system is less sufficiently integrated and not readily accessible，the data quality is not high enough，some judicial personnel are conservative and the talent cultivation mechanism of intelligent trial are yet to be established. Therefore，the construction of intelligent trial should continue to highlight organizational guarantee，embrace the cutting-edge technologies，promote innovation，develop more accessible applications little by little，and reinforce data integration on the platform.
