Wind energy is a clean and sustainable energy, and wind power does not rely on fossil fuels. So there is no fuel price risk, and it, of course, does not include the environmental costs, such as carbon emissions. Because of these unique advantages, wind power has gradually become an important part of the strategy of sustainable development in China. Now with the growing voices on global greenhouse gas emission reduction, and as a clean and efficient energy, wind power has huge potential in combating climate change, energy security pressures and the needs for energy. Wind power in China began to develop from the 1980s. In the first 20 years, the speed of development was slow; but since 2004, it has had an extremely rapid growth.This paper, in order to study the development mechanism of China&amp;amp;amp;#39;s wind power industry, investigated and analyzed the status quo of wind power industry in China, and then found that (1) the development trend of wind power industry in China appears exponential growth; (2) China&amp;amp;amp;#39;s installed capacity of wind power is still smaller than that os some other countries; (3) new subsidy policies bring developing opportunities to wind power industry in China; (4) the sectors of wind power industry are in unbalanced growing; (5) the owners of proposed wind farms are too optimistic though the built wind farm had many problems. In addition, by using the methodology of Game Theory, this paper has also constructed the matrix of pre-assessing risks of China&amp;amp;amp;#39;s wind power industry to further discuss the potential risk factors within China&amp;amp;amp;#39;s wind power industry as risk factors of wind farm construction, risk factors of production of wind turbines, risk factors of parts and components manufacturing industry under risk indicators like R&amp;amp;amp;amp;D, patents, the domestic policy, the international policy, the quality of products and the market regulation, in order to provide a scientific assessment and self-assessment tool for investors or implementers, and also to promote the further development of the wind power industry. 展开更多

With the rapid development of China's urban construction, the acceleration of urbanization and the rapid expansion of population, the effective development and utilization of urban underground space have attracted great attention. Therefore, it is inevitable to study the comprehensive technology of deep underground engineering, and the research results will play an important guiding role in the design and construction of middle and shallow space of underground engineering in the future. This paper analyzes several common construction techniques and methods in the current construction process of urban underground engineering, summarizes the main construction methods of underground engineering, forecasts the development of urban underground engineering construction, and analyzes the safety risks of urban underground engineering construction. 展开更多

The advancement of the fourth industrial revolution has shaped the integration and interaction of different information, communication and technologies (ICTs) in the merging cyber, physical, and social infrastructures. The impact of ICT has accelerated the progress of the United Nation’s Sustainable Development Goals (UN SDGs) and influenced the evolution of smart, sustainable, stable society development. Making the trustworthy information and communication technologies infrastructure widely available will promote the community innovation needed to stimulate domestic economics, provide decent work, and reduce inequalities. This article attempts to outline a big picture about the International Telecommunication Union (ITU)’s trust provisioning framework, including its motivation, current status, and application for achieving the UN SDGs by 2030. This article first describes the purpose of the UN SDGs and the evolution of the industrial revolution, then demonstrates the challenges of global risks affecting the fourth industrial revolution and the need for trustworthy ICT infrastructures. Subsequently, the article evaluates the ITU trust provisioning framework and assesses its applications in the future knowledge society, trust provisioning ecosystem, and cyber, physical, and social infrastructure toward achieving UN SDGs. Use cases are also presented in this article to show the effectiveness of the ITU trust provisioning framework on achieving UN SDGs. 展开更多

Promoting agricultural modernisation through technological change is an important strategy for China.China's carbon neutrality strategy is leading to systemic socio-economic changes that could exacerbate the uncertainty of agricultural development.Therefore,applying a computable general equilibrium(CGE)model,this study characterises the agricultural sector in detail,introducing endogenous technological change proxied by research and development(R&D)to assess the impact of different technological change scenarios on agricultural development under the carbon neutrality target.The results show that allocating carbon revenue for R&D inputs can mitigate the significant negative impact of achieving carbon neutrality on knowledge capital and production in agricultural sectors.Overall,using carbon revenue only for R&D input in crop sectors has the optimal effect on increasing the agricultural sectors'knowledge capital,improving crop production and profit,reducing crop external dependence and promoting the synergistic reduction of carbon and pollutant emissions.However,this scenario has the largest negative impact on macro-economics and household welfare.In contrast,allocating carbon revenue to promote technological change in broader non-energy sectors or both crops and non-energy sectors can effectively mitigate negative socio-economic impacts,but the positive impact on agricultural development is minimal.These findings provide practical insights for the rational use of carbon revenue to expand agricultural R&D investment and ensure balanced agricultural and economic development under the carbon neutrality target. 展开更多

Industrial Parks (IPs) in the Northern Key Economic Zone of Vietnam (NKEZ) have been making significant contributions to the development of the zone since the first two industrial parks--Noi Bai in Hanoi and Nomura in Hal Phong--were established 15 years ago. So far, there have been 51 IPs in the zone, covering a total area of 13,000 ha. Such IPs play a crucial role in mobilizing capital from domestic and international investors for investments in infrastructure enhancement, trade and production aimed at promoting the economic structure transition. However, besides the above benefits, there are a number of unstable factors preventing further development of the IPs. Thus, the objectives of this study are two-fold. The first is to analyze the unstable factors, and the second is to map out strategies to enhance sustainable development of industrial parks in Vietnam's northern key economic zone. 展开更多

This paper applies the Pairwise Panel Granger Causality test to examine the relationship between ICT (information and communication technology) expenditure and the rate of growth of GDP (gross domestic product) per capita. This is accomplished by using cross-country time-series data for a total of 70 developed and developing countries for the period from 2003 to 2008. The study reveals that the existence of causality and its direction differ across different income-group of countries and over the number of lags included. ICT investment expenditure as a percentage of GDP appears to cause the rate of growth of GDP per capita for the high income group and all income groups combined with lags higher than one year. However, for the upper- and lower-middle income groups, the study detects causality in neither direction. Also, when only one lag is included, the study suggests no causality in either direction for any of the income-groups of countries. 展开更多
