relationship between Government and business. The two sessions, General Secretary of Pro, clear the word succinctly summarized the new relationship between Government and business, as pure politics, reshaping the political relationship specified in the direction. District leaders in handling political and business relations, engage in trading power for money, and finally stumbled, we a lesson, always keep in mind that Pro, clean practicing Pro, clear. Pro is to open a sincere engagement with private enterprise to help solve practical difficulties; Clear is to clarify the Division of power, exercised in accordance with, private entrepreneurs with innocent purity, not abusing power for personal gain, not to engage in trading power for money. Third, in order to maintain fairness and justice. Fairness and justice is the lifeline of the rule of law, is the best development environment. Currently, lax law enforcement and the judicial sector in our region also exist to varying degrees, law enforcement departments and individual window units power for personal gains and bribes, thick friends, relations, human cases, money cases in which seriously infringe on the legitimate rights and interests of enterprises and people. Especially some law enforcement and inspection for profit purposes, deliberately looking for corporate loopholes, found directly under the ticket does not give business improvement opportunities. We recruit a company doesnt easily, cultivating a business more difficult, never for personal gain, systematic harassment, card, last checked to check to get the enterprise collapsed. To guarantee the legitimate rights and interests. Always proceed from the overall situation of reform and development of services, fully consider the characteristics of production and management in non-public enterprises and social benefits, an accurate grasp of legal limits, protect the enthusiasm of entrepreneurs and practitioners in innovation and entrepreneurship, enhancing expectations and confidence. To promote strict enforcement. Strengthening law enforcement procedures, improve law enforcement performance evaluation, strengthening the supervision of law enforcement, exploration and practice of risk control mechanism of law enforcement to further standardize the social security, urban management, road traffic administrative law enforcement, effectively free, extensive law-enforcement and lax enforcement of law enforcement and other issues. To uphold justice. Justice is the last line of Defense to safeguard fairness and justice, to unequivocally support the courts and procuratorates independently exercise level . Judicial activities were rampant, must not be allowed to run, favors, money, must not be allowed to knowingly violate the miscarriage, violations of the legitimate rights and interests of the masses must not be allowed to abuse of power, to make forest mass can be felt in every judicial cases in equity and justice. Four to deepen grass-roots governance according to lawchain do long, and put scale big. To serve the development of enterprises. Duocuo simultaneously improving service efficiency, build better public services platform, enhance work efficiency, initiative to help businesses solve the project procedures, financing loans, issues such as land-use approval, reduce operating costs, business travel light and enhance the confidence to overcome all kinds of difficulties and the Foundation, real entrepreneurial passion play entrepreneurship, enhance the internal vitality and creativity.

Environment of rule of law most gather Moss, the most conducive to development. Improving the leading cadres using the method of thought and the rule of law Administration work, problem-solving, the ability to promote the development, is the key to promoting the rule of law. The law may affect the efficiency of out of the path of development will be more smooth, won development gains will be sustained, and end with greater efficiency. Leading cadres at all levels should take the lead in respect of law law, abide by, and actively foster Socialist culture, actively promoting the field of multi-level governance according to law, guide the masses and consciously abide by the law, failing to find law, solve the problem by law, in accordance with the law prevail. XXX administration by law of leading cadres do not exist on the rule of law, law enforcement, casual, and vow not to investors, the new scores and other turmoil. These important expositions on my district create good development environment with highly targeted and guidance, especially the General Secretary pointed out that the chaos in my area also exists to varying degrees, some even quite serious. Leading cadres at all levels must improve the development environment of rule of law as a fundamental task, adhere to the problem oriented, solid and solve the problems in the construction of rule of law, to rule the new effect for development environment improvements. To hold key minority. Leaders of this group, although few in number, but the effect is critical. If a local leaders take the lead right according to law, in accordance with the law, the local CPPCC fresh, pragmatic and efficient development environment. Conversely, if a local leaders of ignoring the law, impunity, not only the political environment will be destroyed, will have serious implications for the development environment. Now, some leading cadres lack of awareness on the importance of learning, that learn or not does not matter. Think efficiency is too low too much, act according to the procedure, than an executive order getting along with. In dealing with complex issues, often speak of settling and done; on the issue of handling letters and visits, like to spend money and buy stop and stable, but disregard the law administration, in accordance with the law, the rulechain do long, and put scale big.

Despite my good social order in General, but there are law-abiding consciousness, social order is not standard, regardless of faith, Twining visit visit and other outstanding problems. We want to actively promote the field of multi-level governance according to law, promote the continuous improvement of the social environment. To promote universal compliance. Actively foster the rule of law culture, carry out law publicity and education on honesty and trustworthiness, guide the masses and consciously abide by the law, failing to find method, problem-solving method, method of gradually changing the world, he is not looking for but someone unspoken rules, formed all law law, abide by the good atmosphere. To strengthen the comprehensive management of public security. Deepening peace xingan construction, strongly against violence crime, mafia and serious criminal offences, to protect the legitimate rights and interests of citizens, legal persons, carry out criminal policy of temper justice with mercy, the maximum stimulating social vitality, and earnestly safeguard social harmony and stability. To resolve social conflicts by law. To further smooth channels of reporting social conditions and public opinion, improving regulation, arbitration, as well as dispute resolution mechanisms, implement fully the petitioners cases third-party hearings and supervising system of letters and calls, and to resolve the involved law lawsuit into the orbit of rule of law, vexatious, Twining visit visit, disturbing social order and other malicious extortion, resolutely crack down. Five, improving cadres Vitale, provide strong protection for forest development XI General Secretary stressed that the comprehensive revitalization in Northeast China, needs a high quality, solid style, cadres of the dare to play. Cadre cadres is a pledge, should want to do work and able to do good, enthusiasm is paramount. Treat party cadres, it is necessary to Strict management, and warm care, enable the broad masses of cadres work hard work, this is two parallel principles. In strict accordance with the standards of good cadres selection and appointment, the real officers, dare officers, those who want to play, good as excellent cadres at all levels of leadership in the past. At present, some leading cadres work initiative is not high, beyond political, idle, lazy governance governance, not as, slow, messy and a phenomenon still exist to varying degrees, affected and restricted economic and social development. We must mobilize the enthusiasm of cadres as an urgent task, adhere to combination of incentives and constraints, and adhere to the strict management and warm care, practical solution for the officers not to problem, motivate cadres and better lead the masses to an undertaking, the cadres and create the new achievement in a dare to play, good at shows as new. To identify the problem, accurate pulseof law to visit and contribute to make visits to the vexatious visits arrogance. On these issues, we need to have a proper understanding, should take the lead to establish a sense of fear of the law, strengthen the application of the rule of law and the rule of law work of thinking and take up responsibility for the construction of the rule of law. Put learning first. Premise is ignorant of the law, abide by the law. Leading cadres at all levels should take the lead in studying the Constitution and laws and regulations closely related to work assumed by, an accurate grasp of the basic position of our party to address the issue of the rule of law, known for the scale to do things, figure out how to use it right, what things do, what not to do, it can never legal literacy. To enhance the awareness of the rule of law. Firmly establish the supremacy of constitutional law, legal equality before the, right by the law makes the right to statutory, as well as the rule of law, develop habits of rule of law, to discard the rule and cannot, must not get overridden by authority, at the right pressure. Should take the lead to abide by. Fulfil its mandate in strict accordance with statutory authority and procedures, no matter what you want to adhere to the law, thought of rule by law and the rule of law to tackle hot issues, effective s
