The "college-college-enterprise" project of Fujian and Taiwan is a pioneering work in Fujian educational practice. The project has achieved remarkable results in aspect of policy level, operation support, training process, and results of cooperation. With the further development of the project, it is facing limitation and difficulty such as recognition of academic degrees, course credit transfer, legislation protection, corporate participation, joint schooling and funds. Deepening the "college-college-enterprise" project of Fujian and Taiwan should be government-led, enterprise-oriented and college-dominant.

Qian Xuesen is the famous mentor of the career,National Defense Science and Technology Information(NDSTI),in China,who helps bring a great contribution towards Science and Technology Information(STI).Based on the study of the documents written by Qian Xuesen about STI,this paper firstly analyzes the characteristics of Qian Xuesen's theories on STI and the status on STI career of China,and then reconstructs and clarifies the architecture and system of Qian Xuesen's STI theories by neatening the involved viewpoints,theories and thoughts,and finally the crucial significance of this architecture is elaborated for the development of modern Information Science.

The rise of China manufacturing industry has won the “World Factory” reputation, but the equipment manufacturing industry of China still in the low-end value chain of the global industrial chain. Vigorously promoting the information and industrialization integration can bring the industry from large to strong. For China, “manufacturing large” to “manufacturing power” points out the direction of development. This paper analyzes the content and level of information and industrialization integration, retroacts the theory of competitive advantage. Taking “diamond model” and “value-chain theory” as the analytical framework, the mechanism of advanced rail transportation equipment manufacturing industry in competitiveness enhancing is analyzed based on information and industrialization integration.

Cooperative innovation of Industry-University-Research is the basic form of national technical innovation and intellectual property strategy is the important content of manufacture-learning-research cooperation innovation. Improving the creation, utilization, protection and management ability in the cooperation of innovation is to promote the further development of the cooperation of the key. This paper discusses the strategy of intellectual property rights promoting the cooperation from four aspects: First, the inoculation intellectual property creating environment. Second, an effective use of intellectual property right. Third, according to law, protect, form four one of the intellectual property rights protection system. Fourth, the scientific management of intellectual property.

In recent years, high-speed railways of our country have gained world-beating achievements. As a modern tool of transportation, from the day of its birth, the high-speed railways relies on its powerful vitality have motivated countries, regions and cities social economical development, especially great function in process of motivating regional economy integration and urbanization. Till now, building high-speed railways has become the common view of governments. Predictably, railway transportation of 21th century will show integrated development of high-speed railway, the age of world-wide high-speed net work has come. Base on empirical research, this article describes development condition of both domestic and foreign high-speed railway, combine with fact of China, from experience mental point of view to discuss function mechanism high-speed railway improving regional economic development, in order to fulfill more achievement in process of Liaoning regional economic development by high-way rail construction.

As a developing country task has not been completed as an industrialized, facing an arduous task of realizing information, promoting two of the fusion vigorously is the inevitable choice which is the release of various development activities in China, socialism with Chinese characteristics power. Promote the two of fusion not only in the development of information technology production equipment, core technology and industry up and down "hard work" but also need in the information management revolution brought about by the waves up and down "soft skill". Based on explaining meaning and effect of Collaborative management, analysis of the "island" phenomenon of two-integration process, using collaborative management philosophy, have speeded up the integration process of the concrete path and the promotion of industry by the "big" to "strong"

As, an important part of state innovation system and base of independent innovation, University Science and Technology Park (USTP) has become one of the main sources of innovation for the regional economic development, technological progress and high-tech district enterprises to start a new undertaking. To integrate the resources of USTP effectively, we should renew its management system and operational mechanism. This paper proceeds from positioning and principle of the design of management system of USTP to analyze the relationship between USTP and its parent university. Clarify the basis for the design of management system of USTP. Design four layers management system of "leading layer - guiding layer - management layer - operational layer", and analyze operational mechanism of USTP from four layers that introducing mechanism, incentive mechanism, innovative mechanisms and integrating mechanism.

With the implementation of the strategy of "Prospering the Nation with Science and Education" and reform of higher educational system, transferred colleges are being in an critical and important period of transition and development. The task of how to continue to serve the original industries after being transferred, not only relates to the development of the original industry, but also becomes the thought-provoking problems in the develop process of transferred colleges. This paper starts from the current situation analysis of Chinese transferred colleges, further explores the environment of transferred colleges' continuing service to original industries and proposes the specific approaches of continuing serve for original industries from two aspects which are the transferred colleges themselves and original industries' policy support.
