The environmental situation facing the development of natural gas in the world is undergoing profound changes, and the positive factors to promote the development of natural gas are more than ever before. The international oil price has gradually returned to a reasonable range, the "shale revolution" in the United States has been deepened, and a new round of energy transformation characterized by green development is accelerating in major economies. The rapid growth of natural gas consumption in China has become the main driving factor for the rapid development of natural gas in the world. Governments at all levels attach great importance to it, all kinds of market entities work together, the output grows rapidly, the diversified supply is enhanced, the construction of facilities is accelerated, and the sales market is booming. At the same time of rapid development, the deep-seated problems and contradictions of unbalanced and inadequate natural gas development in China are constantly exposed, which need to be solved by accelerating development and deepening reform.
