The school-enterprise cooperation, as a personnel training mode adapting to the development of the times, makes ftill use of the resources of universities and enterprises, which is of great significance to strengthen the mutually beneficial cooperation between schools and enterprises and to train the practical talents. However, problems such as the imperfect equipment of private colleges and universities, the inactive participation of the enterprises in the cooperation, and the lack of communication and exchange between the two sides, still exist. Therefore, it is of great practical significance for the development of the national education and the social progress to put forward the improvement measures and accelerate the development of the efficient and mutually beneficial mode of the school-enterprise cooperation.展开更多

The objective is to propose measures for oil and gas cooperation between China and Central Asia. Central Asia is rich in oil and gas resources. Its remaining recoverable reserves of crude oil and natural gas account for 1.9% and 10.6 %, respectively, of the world's total reserves. Moreover, there is great exploration and development potential. As a strategic channel connecting Eurasia, Central Asia has a prominent geopolitical status. Many powerful countries such as the United States, Russia and China, as well as Europe, have an intense energy competition in Central Asia. In the oil and gas cooperation with Central Asia, the China National Petroleum Corporation (CNPC) focuses on establishing a coordination group, promoting overall oil and gas business opportunities and sustainable development, innovating and applying specialty engineering technology and improving project economic benefits. Through its efforts over the last nearly two decades, the China National Petroleum Corporation has completed a 50-million-tonne a year oil and gas production centre in Central Asia and oil and gas pipelines passing through multiple countries, becoming an important channel for securing China's energy imports. If appropriate measures are taken in the 'Thirteenth Five-Year Plan' period or later, the China National Petroleum Corporation will develop a 100-million-tonne p.a. oil and gas production centre in Central Asia and a strategic oil and gas import channel exceeding this amount of production. This cooperation between China and Central Asia is however faced with the following challenges: increasing multinational competition uncertainty, potential risks in the political systems of Central Asian countries, frequently occurring violence and also resource policy tightening in Central Asia. To further oil and gas cooperation with Central Asia, it is recommended that China should develop an energy acquisition strategy, assign a regional energy ambassador, enhance oil and gas supply by mergers and acquisitions, establish regional multinational subsidiaries and improve its risk prevention system.展开更多
