Superconductivity is a novel phenomenon caused by the quantum condensation of large number of electrons in solid state materials, and it involves rich physics principles, including the quantum mechanics and with many potential applications. Superconductors enjoy properties of zero resistivity, perfect diamagnetism and macroscopic quantum phase coherence. Superconductivity can be applied in energy industry, communication, transport, medication, defense and large scale scientific equipment. The discovery of iron based superconductors is a typical example, where Chinese scientists have played essential roles. This can be said as a turning point of researches of superconductivity by Chinese scientists in the field of superconductivity. Since then the Chinese scientists have made many outstanding achievements in this field, furthermore, in many sub-directions of the field, they are gradually playing leading roles.

Over the past more than 70 years since the founding of the PRC, with the changes of the times and the national conditions, the scientific and technological policies of the CPC and the country have continued to improve. As an important part of the basic science, the high-energy physics has also been continuously developed in response to the tide of the times. This paper divides the development of China's high energy physics study into four stages in the chronological order, and discusses the role and the influence of science and technology policies on the development of the high energy physics in different stages based on the background of the times.

In the past 100 years, the development of China's seismological science and technology is a tortuous process, while having achieved extraordinary achievements. In different periods, China's major earthquakes and earthquake disasters have different characteristics, which could be used to guide the development of the earthquake science. National policies and major decisions have also played an important role in promoting the development of the seismological science and technology. The past 100 years can be divided into four stages and the development of China's seismological research is reviewed in each stage in this paper.

Since the establishment of new China, the macro-management system of Chinese museums, under the leadership of the Communist Party of China, has gone through four stages of adjustment, effectively promoting and strengthening the high-quality development of museums. The macro-management system of museums in China features the hierarchical territorial management, the multi-subject management, the multi-mode management, and the in-depth legal construction. In the new era, the integration of the cultural development and the tourism has become increasingly evident, the industry associations and the museum alliances have played a significant role, and the digital construction and the talent mechanism construction have become a new trend in the development of the museum macro management systems.

With the rise and the development of the new generation of the information technology represented by the Internet, the big data and the artificial intelligence, a transformation is taken place in China from the traditional industrial economy to the digital economy. In China, the strategy of the integration of two modernizations is actively promoted, showing evidently the advantages of the complete manufacturing industry, the independence and the integrity and the large scale. The traditional manufacturing industry goes from big to strong in the new wave of the technological revolution and the industrial reform, taking a historical leap from "a follow-up pattern" to "advancing side by side" and further to "a pattern in a leading place". The Internet is regarded as an important cornerstone of the fourth industrial revolution. In recent years, in China, the development and the updating of the industrial Internet are encouraged and supported, focusing on the use of the information technology to improve the total factor productivity. This paper analyzes the construction significance, the development path and the future outlook of the industrial Internet by reviewing the development process of the industrial Internet in China, in order to promote the information and the industrialization in a wider and deeper range.
