International online report (guo hao, China Radio International) : when it comes to South American wine, the first thing that comes to mind is the export of wine from Chile to Argentina. But in recent years, wine from the mountains of south Rio grande, southern Brazil, has been rising to prominence in the international wine market because of its crisp taste and high "cost performance". And China, a big consumer of wine, is a "key target" for Brazilian vintners. In the past year, Brazil has exported nearly 200,000 bottles of wine to China, and some Brazilian wineries have set up shop in China and even opened online stores. Brazilian red wine is quietly entering the Chinese people's table. Gasoline is the largest oil product consumed in the United States last year, according to the U.S. energy information administration (EIA). Last year, gasoline consumption averaged about 9.3 million barrels a day (391 million gallons) a day, a record high, about 47 percent of U.S. oil consumption. In the face of market failure, coase has given the opposite answer: external-utility problems can be solved by explicitly using the market, without government intervention. And zhang wuchang is more absolute, he said that there is no so-called external utility, there is only unclear property rights. Anyway, coase brought revolutionary innovation to market concepts. He made it clear that the key to the market was not the "price mechanism" of impersonal machinery, but the power of participants in economic activity. An open market enables enterprises to compete and cooperate with each other on a larger scale and at a higher level to promote economic development. With the development of social division of labor and market economy, the concept of market is also developing and deepening, and the multiple meanings of different levels are reflected in the deepening of the project.
