The index system of high-quality development of natural gas has important theoretical value and practical significance for promoting the development of natural gas in China.At present, there are few researches on high-quality development of natural gas at home and abroad,few researches focus on theoretical level, and index selection also has certain limitations,and it is difficult to effectively measure the state and level of high-quality development.In 2018, the economic work conference clearly pointed out that it was necessary to accelerate the formation of the index system to promote high-quality development.Based on the analysis of the current situation, opportunities and existing issues of natural gas development, this paper systematically studies and constructs a high-quality development index system of natural gas,focusing on both the current problems and the long-term mechanism.The theory and practice are pressing ahead at the same step, which provides a guiding role for the high-quality development of natural gas in China.
