thrift of excellent traditional and style lack deep of understanding, one-sided think in now of good situation Xia, economic smooth more fast development, and reform made major progress, and people living significantly improve, and social the career made new progress, no necessary always hard has, no awareness to China also has many poverty area, and also has many poverty population of exists, more living improve has, more need keep hard of style. Three is not strictly honest. Total thought units is a water sector, clean self-discipline away from himself too far, no real processing good living of improve and hard, and thrift excellent traditional of relationship, no effective do comply with Constitution and party of regulations must from I do up, no right mercy good bitter Le, and wealth of relationship, no right awareness to in comply with Constitution and party of regulations aspects everyone has accountability. Four, future direction and improvement measures 1, belief and faith, strengthen party spirit. One is to firmly establish the noble ideals of struggle for the ideals of communism, communist struggle for life, ready to sacrifice everything for the party and the people. Second is to continuously improve the quality and standard of political, conscientiously study Deng Xiaoping theory and three represents important thought and the scientific Outlook on development, implement the partys basic program for the primary stage of socialism, adhere to the correct political orientation, maintain highly consistent with the CPC Central Committee, is good at theories of socialism with Chinese characteristics to analyze and solve problems. Third, strengthening the party spirit and the world transformation, perseverance of the party Constitution, relive Party vows to establish correct world Outlook, Outlook on life and the world, practically embodies ideals and beliefs into action, combine lofty ideals and practical activities, transforming the objective world, actively participate in the great practice of building socialism with Chinese characteristics. 2, keep the purpose in concept, changing the style of work. First, keep in mind that the purpose of serving, adhere to assuming power for the people, keep in mind the people and care about people, and the joys and sorrows of the masses, .According to city discipline, and municipal organization Department requirements, today we held implement implementation independent Commission against corruption guidelines effective strengthening led cadres style construction topic democratic life, main task is close contact thought, and work actual, control check district Standing Committee team and the personal in implementation independent Commission against corruption guidelines Shang exists of problem, in-depth carried out criticism and self-critical, further clear rectification direction and measures, effective enhanced clean politics of consciousness and initiative, firm set good of ruling image.

Good for this meeting, we requested the Standing Committee of the municipal party Committee, municipal Secretary General Tang Wenjin, the City Commission for discipline inspection Standing Committee Yang Xu, Jiang Jixue, Deputy Director of the personnel office, and other leading comrades present guidance allows us to warm applause for their welcome and thanks! Below, I first District Committee member of the 20XX team annual democratic meeting implementation of the corrective measures, as well as member of the team and of my own report guidelines for the implementation of the independent Commission against corruption statement invited leaders and comrades criticism. First, annual party on the 20XX team, Member of democratic life action plan implementation year 20XX, district democratic meeting a member of the team on study and practice the scientific Outlook on development theme, find a project supporting strong enough, the industry well enough, urban construction management level needs to be improved, livelihood improvement needs to be strengthened, district team itself, such as the five aspects. Year of 20XX, we find out the problems mentioned above, based on actual Shunqing construction and development, conscientiously sum up improvements, achieving significant development results and effectiveness of their work. (A) highlight the project handle, maintain high growth of investment. Adhere to the strategy as a Foundation, carrying out projects to promote increased stamina important. One is to increase the intensity of projects towards. Actively seek national and provincial policy support, superior special transfer payments, a variety of additional income will top 700 million Yuan, a number of key infrastructure projects, livelihood projects, industrial projects into the cage. Second, increasing the project attracts. This year a total of 23 signed a major project, of which 14 billion project, China Metallurgical group, vanke group, Guangdong hengda group, Taiwan Ruentex group, on the RI group, Shenzhen Kaisa, jifeng agricultural machinery, Mercedes-Benz, Audi 4S store and other large enterprises and projects have settled in Shunqing. Third, strengthen project construction. Annual implementation focus project 39 a, fixed assets investment total will breakthrough 12 billion yuan, created district yilai history high, South door dam, and five in shop old city transformation, and Ying China industrial concentrated district construction, and city main road construction, and Northeast steam Trade Center, and modern farmers industry Park, and vocational education city, and low rental, and also room construction, and features blocks build, and farmers market transformation, and rural version Street transformation, focus engineering speed up implementation, effectiveness obviously. Expected to be achieved this year, area-wide GDP 17 billion
