City Government offices adhere to strengthen and improve the construction of the system as a breakthrough, has developed a series of code of conduct, continuous improvement of operational mechanism, sound and the implementation of the rules and regulations, and adhere to the system of managing people, according to the rules, the work gradually into the orbit of institutionalization and standardization. Focus on strengthening ideological and political construction of the contingent of cadres, and actively carried out various business training, knowledge of the Office team structure has been optimized, to broaden the range of knowledge and operational capacity grows, nurtured a political firm, sharp, professional and innovative staff, created solidarity, striving for the top, pragmatic, dedication, good image. However, with the State Council and the provincial Government of the national, the province's Secretary-General meeting of government offices under the new situation the functions and priorities compared to the requirements of our gap is still very big. Main is daily in the passive meet of more, active research of less, service also has not timely, and not in place of problem; work in the meet Yu traditional of, and program of of work way, develop innovation spirit and service innovation capacity not strong; supervision information work and promoted decision implementation of contact enough close, feedback situation not active; research resources of using enough full, research results of into degree not high; some sector documents running not specification; Municipal Government Office on the County (district) and municipal government sector Office work of guide enough, No real form interaction and close collaboration, promote the implementation of the work. These problems, we must effectively be addressed in the future work. Second, serve the overall situation, carry out their duties, improve quality, and strive to create a new situation of system of government offices in the city since last season, meeting the Secretary-General of the State Council and the provincial government has held a government system, from a global and strategic height, scientifically analyzed the new situation and the newTasks on the system of government offices bring new situations and new problems and new challenges, profoundly expounded the work of government departments at all levels in the new era should be put in the situation to understand, to grasp, to deploy at any time and under any circumstances, should always focus on the big picture, firmly grasp the overall situation, increasing in the overall implementing in earnest the work of spontaneity, initiativeSecondly, we should strengthen the team. A unit is a team in various sections of the unit inside is also a small team. A unit with a team spirit, formed a team responsibility, cohesion and competitiveness. You want to make a unit, a Department work improvement, must be melting inside a feeling of solidarity and mutual help, for a common goal and determined to achieve the spirit, cultivating a strong collective spirit and team responsibility, sense of honor. Therefore, we need to start improving office work and enhance the efficiency of Office work and strive to build a concerted . Fault. In accordance with the requirements of modern management science, establishing strict responsibility system of management by objectives. A work who is in charge, who is in charge and who is responsible, what right do these people have, what responsibility, has to truthfully and clearly understood. Departments at all levels should strictly implement the check in the Office of party Committee evaluation, significant accountability and reward incentive system, pay close attention to duty cash and making unity, rights, responsibilities, and to inspire each of cadres spirit and morale, Super courage. Investee insists, is a deep topic, is a real problem, is a big issue. Today, I just combined this year, the city's Communist Party Committee Office, had some rough talk and understanding, we must strengthen research and exchanges in this regard in the future. Investee in the new year, we must hold high the banner of Deng Xiaoping theory and the "three represents" theory the great banner of, under the correct leadership of the CPC, adhere to the people-oriented, insist on truth, adhere first to excellence, efforts to do Office work to a new level.

And explicitly put forward the "surrounding situation, pay attention to implementation" is the core of government offices, requiring government departments at all levels cannot be "Gramophone", "mail room" and "the Messenger" is not confined to paper communications, yinglaisongwang and upload issue. Must to has strongly of implementation consciousness, this is Government Office sector first bit of task, to first, and is duty-bound, insisted reported truth, and told truth, and out confess, and do facts, and pragmatic effect, put work of to points real put to research solution reform development stable in the of major problem Shang, put to research solution masses production life in the of urgent problem Shang, put to research solution work in the exists of highlight problem Shang, put an end to to Conference implement Conference, to file implementation file, never can makes superior of decision and deployment in a "implementation" Lost in the sound. System Office of the Government sector must take the lead in party and Government policies, the deployment and carry out specific targets, in the implementation efforts, for example on the implementation, on the implementation of a performance. City Government System Office to seriously implement implementation national, and Province Government system Secretary-General Office Director Conference spirit, according to around overall, grasp implementation this a general requirements, insisted reform innovation, further change management concept, and management functions, and management system and management method; insisted quality first, ensure for led, and for grass-roots, and for masses provides quality efficient service; insisted strictly rule political, efforts construction a support political firm, and business master, and service political clean, and style excellent of Office team. Concrete work, and must deal with "three relationships": one is to handle well the relationship between passive adaptation and active service. Office service functions to the passive aspect of its work, which requires us to host lead when action must be strictly in accordance with the intentions and requirements for leadership, work within the limits of delegated authority, not offside, participation in the intervention, and not decision-making, coordination is not contemplated. Meanwhile, Office work and must become more conscious, give full play to the initiative and work to some foreseeable, be proactive, prepared, thinking ahead, providing information, active leadership, reflect the situation, ahead of good research, reference point, in key places to promote overall efficiency. Second, to handle the relationship between administrative services and transaction services. Administrative services and Services Office services complement the two aspects of the job. Administrative services is the core service is guaranteed. Note that combines both, adhere to government service as the main line, the Chief turns around the overall situation, turns around the district. On one hand, will attachthree a representative" important thought for guide, efforts adapted new situation, and new task, and new requirements, tightly around city reform development of overall, further change functions, strengthened service, determined to innovation, Government System Office overall work of quality and level h
