The 2019 annual assessment of “Improving the rule of law for the Business environment” consists of three secondary indicators，namely，“examination and approval system reform”，“Government integrity” and “Improving the business environment promotion mechanism”，which are divided into six specific observation points，forming a macro investigation of the government’s efforts to promote the rule of law of the business environment. The total score of this index is 80，and the average score of the 100 cities evaluated is 47.39，with an average score of 59.24%. Although the score is somewhat higher than the average score of 57.83% in 2018，there is still a large space for improvement. The assessment results of the past two years show that the assessed cities have made certain progress in optimizing the legal guarantee of the business environment，such as significant progress in the reform of commercial examination and approval，continuous optimization of administrative examination and approval services，a more sound legislative system for optimizing the business environment，and increasingly fruitful results of fair competition review. However，at the same time，there are still some problems，such as the incomplete reform of administrative examination and approval，the urgent need to reduce enterprise transaction costs，the insufficient protection of entrepreneurs’ rights and interests，and the need to strengthen the construction of government integrity. In order to further strengthen the rule of law of the business environment，it is necessary to ensure equal access to public resources，strengthen equal protection of all kinds of property，promote fair and unified market supervision，strengthen the credibility and promise of administrative organs，and enhance the convenience and efficiency of dispute resolution.
