Abstract: With the continuous emergence of new technologies such as the Internet of Things, blockchain, big data,and artificial intelligence, crimes committed by means of new technologies have also arisen. The governance of new types of crimes is inseparable from reliance on technical experts. As individuals with specialized knowledge,technical experts mainly undertake work such as inquests and examinations, forensic appraisal, and technical consultations and investigations in assisting criminal investigations. The qualifications, responsibilities, and appointment of technical experts, together with the procedures for their assistance in investigations, directly affect the legal effect of expert-assisted investigations. Although China has established relatively mature legal systems in areas such as inquests and examinations assisted by individuals with specialized knowledge and auxiliary forensic 
appraisal, the increasingly prominent digital and intelligent characteristics of new types of crimes have brought new challenges to the work of technical experts in assisting inquests, examinations, and forensic appraisal. There is an urgent need to respond by improving the existing systems and strengthening legislation in this field. Foreign countries have valuable experience in aspects including expert qualifications, responsibilities, appointment, procedures for assisting investigations, and the legal effect of such assistance. Therefore, examining the expert-assisted investigation systems of foreign countries is of important reference value for improving China’s legislation in this field and regulating expert-assisted investigation practices.
