Environment to be counted in official's political performance rating system is thought of as a new institutional mechanism in China facilitating its sustainable development and then global sustainability. Then its significance is narrated and visions in future are envisioned. In the end, certain concrete suggestions for the rating system are given in a practical way.展开更多

Two gold award papers and 10 silver award papers were awarded, and the other 34 papers recommended into the final judgement were nominated as excellent papers.展开更多

In this respect, it has achieved great success in basic research, development research and hi-tech production work, which are considered as three mainstay fields, because the institute sticks to the line of "taking national economic development as the goal, high-level research and advanced scientific and technical achievements as the target." In recent years, the general planning of the research and development work at the Institute of Mechanics has focused on the goal of promoting economic and social development in China.展开更多

It is the condensed embodiment of the tension and conflict between the determinate and the creative, the natural and the transcendental in the structure of human existence. Its dynamic and constraining mechanisms are specifically manifested as the tension and conflict between innovative and conservative ideas, open and closed ways of thinking, and modern and traditional cultural patterns. In the course of a new emancipation of our thinking, we should not only actively promote specific emancipation of the mind on every level and in every sphere, but also highlight the establishment of mechanisms and institutions for such emancipation, and especially the formation of a mechanism for cultural innovation. We must create an institutional culture that respects different ideas; establish a mindset that is open, tolerant, creative and cherishes difference; and cultivate a cultural model that respects individuality and innovation.展开更多
