Some of the recent methoddevelopment efforts by Chinese microbiome scientists and their international collaborators that underlie these technological trends are highlighted here. It is our belief that the China Microbiome Initiative has the opportunity to deliver outstanding ＂Made-in-China＂ tools to the international research community, by building an ambitious, competitive, and collaborative program at the forefront of method development for microbiome science.展开更多

In the view of China’s situation, this article analyzes the experiences of OECD in high and new technology industry and gives a statistics index system along with the evaluation method to estimate the development of high and new technology industry.展开更多

As a consciously applied scientific method of analysis it is a reflection in the mind of the objective dialectics of the economic realm, consisting of applying the analytical fimctions of Marxist economic categories and principles and grasping the dialectical elements in the analytical approach of historical materialism. Compared with the analytical method of Western economics, the economic analytical method of historical materialism is markedly more scientific and advantageous. It is innovative in theoretical terms due to the scientific nature of historical materialism.展开更多
