The quantity of asset data continues to grow, with internal value reflected in education, management, and services, while external value is reflected in policies, resources and reputation. Therefore, effective management of university assets is particularly important. Blockchain is an important infrastructure for Digital transformation, which provides a trusted environment for the occurrence of various collaborations and will reshape many collaboration mechanisms. This paper discusses the current situation and problems faced by universities in the process of Digital transformation. We analyze the development opportunities brought about by Digital transformation and the specific problems faced by physical asset management in detail. We discuss the data platform optimization, asset data application, digital asset security, planning strategy, and construction path of digital transformation involved in the physical asset management of universities.展开更多

On the basis of natural and geographical differentiation of valley, we give an overview of the spatial distribution of valley in mountainous areas of Beijing and spatial difference in valley density, and sum up the typical development pattern of valley economy, using DEM data. The results show that the spatial distribution of valley presents an asymmetric shape of inverted V or branch; Miyun, Yanqing, and Changping have high valley density, while Pinggu, Fangshan and Mentougou have low valley density; there is a significant positive relationship between valley density and the spatial distribution of river and reservoir. The development pattern of valley economy is divided into five types: leisure and high-end upgrade-based pattern, ecological development and transition demonstration-based pattern, folk culture and creation-driven pattern, scenic spots-driven and valley-linked pattern and leisure agriculture and specialty-led pattern.展开更多

Traditional asset management is inefficient. Information is not transparent and management responsibilities are unclear. This paper analyzes the difficulties in the process of asset management in universities and discusses the advantages of blockchain technology. We research on the application of blockchain technology in the process of asset management in universities and propose a framework design based on blockchain technology to standardize the asset management process. The result improves the efficiency of asset inventory and ensures the credibility of asset information. It helps to prevent asset information tampering, and improves the security of asset data. It also pushes the asset management mode from static to dynamic.展开更多

Valuation of ecosystem services is favorable for people realizing the importance of natural ecosystem to human being, and considering its long-term influence on sustainable development of human society when making decisions. Besides, it is an attempt of ecology, geography and other natural sciences to influence social decision process by economic methods. The Value of the World's Ecosystem Services and Natural Capital, written by Robert Costanza et al., in 1997, is generally regarded as a masterpiece for the research of valuing ecosystem services. However, the classifying standard of ecosystem services, the method of various services summation and the purpose for static global value, had confronted many criticisms. Still to now, accurately valuing ecosystem services is not easy, because of the complexity of natural ecosystem, the weak capability of economic system to pricing ecosystem services and the lack of more study in this field. Based on the criticisms summarizing and comprehensive analysis, further study suggestions of ecosystem services valuation is presented: multi-scale integrated and community participation applied in evaluation, dynamic changes of material value and intangible value of ecosystem services, investigation and simulation studies of the marginal value when ecosystem services changed, associated with related areas like ecological compensation research, and research on the market-oriented evaluation of ecosystem's intangible values.展开更多

Transportation is thus an issue of concern, and is a major drive behind the China Belt-and-Road cross-border transportation cooperation initiative. In this sense, the Balkans in Southeast Europe, with its very important geopolitical position, has great potential for connecting up the Eurasian markets and further promoting Sino-European trade. On December 17, 2014, the prime ministers of China, Serbia, Hungary and Macedonia reached an agreement to develop a new trans-continental transportation passage, namely, the China-Europe sea-land express passage, using the Hungary-Serbian railway as the basis. Given the benefit to the general public, transportation infrastructure is usually economically inclusive and politically well accepted, and therefore should be studied from both geopolitical and geo-economic respects. Prudent study of the status and insufficiency of current freight transportation passages is meaningful in both theory and practice. So too is an objective assessment of both the risks and prospects of building of a new passage.展开更多
