General Secretary Xi Jinping pointed out at the Fourth Plenary Session of the 20th Central Commission for Discipline Inspection that it is necessary to deepen the promotion of joint investigation and treatment of corruption, emphasize the integration of rectification, discipline and anti-corruption, and severely punish the intertwined problems of corruption through "joint investigation", and eradicate the common root causes of corruption through "joint treatment". The Fourth Plenary Session implemented the spirit of General Secretary Xi Jinping's important speech, made arrangements for improving the mechanism of investigating and treating corrupt practices and corruption, and focused on promoting the deepening of the integration of rectification and anti-corruption. It requires the use of "investigation" and "treatment" to block the evolution of corrupt practices. The simultaneous investigation and governance of corruption is a deepening of the understanding of the regularity of the construction of Party conduct and clean governance, as well as the fight against corruption. A large number of cases have shown that the leaders who were investigated and punished did not engage in corruption from the beginning, but opened up gaps in their work style issues such as a pack of cigarettes, a bottle of wine, a meal, and a red envelope, and gradually embarked on the path of corruption and decadence. Although there are differences in the forms and degrees of harm caused by unhealthy practices and corruption, they are interrelated and share the same root and origin. Unhealthy practices breed and conceal corruption, and corrupt behavior exacerbates and even gives rise to new work styles. We must deeply grasp the characteristics of the transition from moral and corruption, from quantitative change to qualitative change, apply systematic concepts and dialectical thinking, adhere to the integration of Party spirit, Party conduct, Party discipline, and anti-corruption, and strictly rectify the "four winds" with the concept and requirements of investigating and governing together. We must constantly punish corruption and promote the deepening of the integration of positive conduct and anti-corruption. The problem of wind corruption has the same root and source, and requires simultaneous investigation and treatment. The relationship between unhealthy practices and corruption, which are interrelated and rooted in the same source, determines that only investigating corruption without correcting unhealthy practices makes it difficult to effectively control corruption; Without continuous reinforcement of the work style dam, the achievements of corruption governance will be difficult to maintain and consolidate. We need to further improve the mechanism of investigating and treating corruption, not only by "investigating corruption through corruption" to prevent "using corruption to cover up corruption", but also by "rectifying corruption through corruption" and examining the problems of indulgence and extravagance behind corruption. At the same time, it is necessary to unite the work force and comprehensively use supervision models such as "group", "room group", "room group", etc., strengthen information exchange, complementary strength, resource sharing, and work connection, and achieve the expansion from investigating and punishing individual cases to investigating and treating corruption together and solving common problems. Strengthen the cooperation and cooperation between disciplinary inspection and supervision organs, public security, auditing, finance and other departments, establish a mechanism for reporting and investigating violations of eating, drinking, driving and drunk driving, and other issues. This will not only dig deep through the line of "investigating corruption by wind", but also break through the two-way breakthrough of "rectifying corruption by wind", cut off the chain of wind and corruption, and achieve systematic and comprehensive treatment. The simultaneous investigation and treatment of corruption is not only an important means to solve the stubborn problem of work style, but also a necessary measure to eradicate the soil and conditions that breed corruption. At present, the situation of anti-corruption struggle is still severe and complex, and the task of eradicating the soil and conditions that breed corruption is still arduous and heavy. It is necessary to further improve the integrated promotion of the work mechanism of "dare not be corrupt, cannot be corrupt, and do not want to be corrupt", effectively connect the "dare not be corrupt, cannot be corrupt, and do not want to be corrupt", strengthen the concept of "full cycle management", and integrate the investigation and treatment of corruption into all aspects of petition reporting, supervision and inspection, review and investigation, inspection and patrol, and implement it in warning education, rectification and rectification, and system construction, forming an effective closed loop. Establish a sound mechanism for investigating and collaborating on leads, strengthen communication and coordination with departments such as auditing, finance, and statistics, and promote the integration of anti-corruption investigation and treatment throughout the process of lead transfer and disposal, supervision and inspection, review and investigation, so as to continuously transform institutional advantages into governance effectiveness. Deeply grasp the intertwined characteristics of unhealthy practices and corruption, and use "investigation" and "treatment" to block the evolution of corrupt practices. Combining case analysis with similar case analysis, on the one hand, we urge the regions and units involved in the case to rectify, and on the other hand, we strengthen the research on the laws and characteristics of corruption cases, accurately grasp the regional, industry, and stage characteristics, and make good use of disciplinary inspection and supervision suggestions to promote deepening reform, plug loopholes, and standardize the exercise of power for common problems, recurring problems, and issues strongly reflected by the masses. At the same time, it is necessary to establish and improve the leadership system and responsibility implementation mechanism, adhere to the main responsibility of the Party committee (Party group), the supervision responsibility of the discipline inspection commission, the responsibility of the Party committee (Party group) secretary as the first person in charge, and the "dual responsibility" of the team members, and build a responsibility system for promoting integrity, discipline, and anti-corruption. Strengthen overall coordination, break through the bottlenecks and difficulties that affect and constrain the investigation and treatment of corruption, and plan, deploy, and implement the rectification of work style, investigation and handling of cases, and the promotion of reform and treatment through cases. Promote the standardization of the entire process and the linkage of the entire chain of investigation and treatment of corruption. (New Society)
