Contents and methods of economic crime investigation

(a) the method of preliminary investigation. In the initial investigation, compulsory measures cannot be used to restrict personal and property rights. Therefore, how to find out some facts of the case and prepare for the investigation is a problem worthy of in-depth discussion. In this regard, some commentators pointed out that in the initial investigation, it is necessary to adapt to the case and grasp the key points. Second, we must follow the line and judge the nature. Third, we must stop at the surprise attack and take decisive measures. During the initial investigation, compulsory measures and investigation measures such as search and seizure cannot be taken, and only general routine investigations can be carried out. Therefore, the investigation must pay attention to strategies to avoid touching the defendant and destroying his evidence. The following points should be grasped in the initial investigation: first, the criminal suspect provided by the clue should be investigated; Second, quick response and quick decision-making; The third is to focus on secret investigation and try not to contact the defendant; Fourth, the investigation work should be focused, starting with the most easily broken links; Fifth, pay attention to collecting evidence in time according to law; Sixth, we must seize the opportunity to file a case for investigation in time.

(2) Arrest criminal suspects. The arrest of criminal suspects occupies a large proportion in economic crime investigation, and it is also a major difficulty in current economic investigation. Someone suggested. The difficulties in pursuit can be solved by the following ways: first, improve the technical ability and work responsibility of the pursuit subject; The second is to improve the construction of relevant legal systems; The third is to strengthen the cooperation mechanism of economic investigation and pursuit; The fourth is to bring the new mechanism of "solving crimes and pursuing crimes" into the track of comprehensive management of social security; The fifth is to increase publicity. The sixth is to implement funds and provide necessary material security; Seventh, grasp the psychological characteristics of economic criminal suspects and formulate corresponding countermeasures. Some people think that in order to really do a good job in pursuit, we must give play to four advantages: first, combine special groups to give play to the advantages of mass work; The second is to strengthen basic work and give play to the advantages of "online combat and online pursuit"; Third, strengthen measures to give full play to the advantages of professional work; The fourth is to strengthen cooperation between regions and departments. Some commentators also put forward practical means to arrest economic suspects in combination with investigation practice.

(3) General investigation methods and strategies. The investigation of economic crimes is more antagonistic, and only by adopting correct methods and strategies can we ensure the victory of defeating the enemy. Some commentators have made a preliminary study on the concept, main characteristics and principles of economic crime investigation strategy. Some commentators believe that economic crime cases should be examined before they are put on file. Do a good job in the identification of documentary evidence or commodities, find out the nature and expand the source of clues; Seize the financial audit, check the flow of the infringed object, and find out the criminal suspect's means of committing crimes and the scope of activities; Grasp the characteristics of clues such as communication and traffic, and find the whereabouts of criminal suspects; At present, the interrogation of criminal suspects and the verification of criminal facts have just started, and the research on economic crime investigation strategies and methods has just sprouted. The above discussion is of great significance to enliven the theoretical research in this field.

(four) the investigation methods of various cases. At present, the investigation methods of various economic crime cases are the focus of theoretical research, especially various economic investigation textbooks, which elaborate the investigation methods of various cases in detail. However, if carefully scrutinized, the investigation methods of various cases discussed are somewhat similar. This reflects that the current theoretical research of economic investigation is not mature, especially in the research methods, lacking the support of practical experience. Investigation is an empirical science, and theoretical research can only play a guiding role in investigation practice if it comes from investigation practice. As a new branch of investigation, economic investigation should be deeply rooted in investigation practice.
