since the Eighteenth Party Congress，the CPC Central Committee has put forward and strictly implemented the “two responsibilities” system and made new breakthroughs in the theory and practice of the system of responsibility for the construction of Party conduct and building of an honest and clean government：the responsibilities of Party committees and discipline inspection commissions become clearer and more specific；new measures for the implementation of the responsibilities have been adopted；the system of accountability for supervision and implementation has been strengthened；new reforms have been carried out on the discipline inspection system；innovative methods have been developed to transmit pressure through different layers；and those who violate relevant rules and regulations have been investigated for liabilities. Nevertheless，various problems，such as unwillingness to take up responsibilities，lack of focus on the main responsibility and principal works，and defects in mechanisms for the assessment of responsibilities，still exist in some locality，government departments and work units. To solve these problems，the relevant Party organizations must be problem-oriented，adopt multiple measures to strengthen the sense of responsibility，continue to deepen the reform of the discipline inspection system，promote innovation in the system of supervision by discipline inspection organs，and improve responsibility assessment mechanism.
