Abstract: Oil and gas resources have completed commodity attributes, but the strategic roles of the national economy and industrial development cannot be ignored.They are generally considered as the strategic energy resources.It is an inevitable choice to make full use of foreign resources under the imbalance between supply and demand of oil and gas resources in China.The oil and gas industry has high investment risk and long operation cycle whose chain is restricted by politics, economy, market, technology and other influencing factors, and the terminal price is the results of development levels of multiple economies and many sides games.In the recent years, with the low international oil prices, slowing global economy, complex geopolitics, frequent regional conflicts and increasingly sharp game between major powers, the global investment environment of oil and gas resources is becoming complex, volatile and unmanageable.This paper summarizes and analyzes the new changes of the global oil and gas resources investment environment in the china’s perspective, and puts forward the risks and challenges of “going global” to obtain foreign oil and gas resources of China’s enterprises, and then, puts forward some suggestions.
