rapid development of the market economy environment to explore public servants duty consumption monetization reform has provided a good foundation. The socialization of rear service work has been launched, and rapid progress in some places and departments, duty consumption monetization of carrier and approach to management has been resolved. Third, in recent years, exploring the monetization of duty consumption has made some progress, have gained some experience and can provide reference to the comprehensive reform of the system of public servants duty consumption further. Implementing an honest canteen, standardize official entertaining management; enhancing the telecommunication expense management; elimination of County travel and countryside subsidies; research village officials capitalization management of corporate spending, and so on. Finally, group .18 session to be held in Beijing from November 9, 2013 to 12th. 35 years ago blew the third plenary session of the reform and opening up in the spring breeze, changed, affect the world; today, 35 years later, in the eyes of the nation and the world expect, again to reform mark China, ushered in the 18 session. XI General Secretary pointed out that Chinas reform has entered a crucial period and the Sham Shui Po District, must be based on greater political courage and wisdom, lose no time in deepening reform in important fields. Dares to crack a hard nut, dares to question the Rapids, which dares to break the barrier of ideas, and dare to benefit cure barriers. Deepening reform and opening up is on schedule to achieve institutional safeguards of the moderately well-off. Under the five in one the General layout of socialist modernization requirements, 18 session of the decision was a five in one and the improvement of overall scheme of reform, will promote an integrated and coordinated economic, political, cultural, social and ecological civilization construction of the five reforms and the partys construction in the area of institutional reform. The five in one programme is to achieve a comprehensive reform of institutional guarantees for objectives of build a well-off society, the smooth progress of the construction of a well-off society and reform the objectives of the programme. One, holding time and place importance on November 9, 2013 to the 18 session of the 12th Beijing since 1978, 35, have been 7 plenary session, each time on major issues of political and economic life of the country has made important deployment. In accordance with PRC political practice, often at every session of the CPC Central Committee in a plenary session was held immediately after the partys Congress, on the theme personnel, discussing election Centrals top leaders, such as the election of the Standing Committee of the political Bureau, through the Central Committee members, decisions, such as members of the Central Military Commission. The second plenary session, is held in two sessions before the general election, mainly to discuss a new State personnel issues.

Previous plenary session is often branded with a central leading collective, often by looking at the third plenum of the initiative to found the current central leadership collective governance characteristics. From the analysis of the process of economic reform in China, plenary session, 12 session, 14, 16 plenary session have programmatic meaning, respectively, marking the four stages of Chinas economic reform, and that the start-up phase of reform, reform, construction phase and perfecting the Socialist market economy framework stage of socialist market economy. Previous plenary session topics proposed to the third plenary session of taking class struggle as the key link, shifted to socialist modernization; 12 session marked the change from rural to urban, established with public ownership as the Foundation of a planned commodity economy; 13 session at a time when both the old and the new system change, governance and rectify the economic order; 14 . Fair and efficient and authoritative Socialist judicial system, safeguard the peoples interests. Legal authority to uphold the Constitution, deepening the reform of administrative law enforcement, ensure that the right to exercise judicial power independently and impartially according to law the prosecution, perfecting the running mechanism of judicial power, improve the system of judicial protection of human rights. Plenary session, Affairs the right to adhere to the system, and let the people authority to let the power run in the Sun, is shut up in a cage of the system power policy. Decision Science, implementation should be constructed strong, supervise the running of powerful system, improve the system of punishing and preventing corruption, promoting political integrity, and strive to achieve cadres honest and Government integrity, clean politics. To form a scientific and effective coordination of power restriction and mechanisms to strengthen anti-corruption institutional innovation and institutional protection, sound improvement style normal system. Plenary session, building a socialist cul
