Quo Vadis public television? Market position of selected Western European countries

The liberalization of television markets and the emergence of commercial channels has changed the position of public television, bringing an end to monopolies. Public television now competes for audiences with private television. In this paper, the authors analyze the changes to the market position of public television in Germany, Spain, France, the United Kingdom (UK), and Italy between 1995 and 2019. In this 25-year period, all of these countries have had a liberalized TV market. The aim of this paper is to demonstrate the ways in which public television competes with commercial television, assessing the consequences of this on market power. This analysis allows us to detect similarities and dissimilarities between public television and television markets in large Western European countries. The results show the decline of the market share of public television in all countries, except Germany. Furthermore, public television has remained market leading in all countries, with the exception of Spain. One of the ways to compete with commercial television is to start new public channels and acquire a large audience.     

Trends and driving forces of low-carbon energy technology innovation in China’s industrial sectors from 1998 to 2017: from a regional perspective

Low-carbon energy technology (LC) innovation contributes to both environmental protection and economic development. Using the panel data of 30 provinces/autonomous regions/municipalities in China from 1998 to 2017, this paper constructs a two-layer logarithmic mean Divisia index (LMDI) model to uncover the factors influencing the variation of the innovation of LC in China’s industrial sectors, including the alternative energy production technology (AEPT) and the energy conversation technology (ECT). The results show that China’s industrial LC patent applications rapidly increased after 2005 and AEPT patent applications outweighed ECT patent applications all the time with a gradually narrowing gap. Low-carbon degree played the dominant role in promoting the increase in China’s industrial LC patent applications, followed by the economic scale, R&D (research and development) efficiency, and R&D share. Economic structure contributed to the increases in LC patent applications in the central and the western regions, while led to the decreases in the eastern region, the north-eastern region, and Chinese mainland Xizang(Tibet) Autonoomous Region is not considered due to lack of data. This note applies to the entire article.. Low-carbon degree and economic scale were two main contributors to the growths of both industrial AEPT patent applications and ECT patent applications in Chinese mainland and the four regions. Several policy recommendations are made to further promote industrial innovation in China.     

Factors influencing the use of artificial intelligence in government: Evidence from China

Some studies have discussed the potential and challenges related to the use of artificial intelligence (AI) in government. However, there are few empirical studies that have examined factors that influence the use of AI in government. By collecting policy documents and empirical data from the government, IT enterprises, and the public in China, we identified the influencing factors in the three stages of government adoption, implementation, and decision-making. The research results show that the influencing factors of government application of AI are different at different stages and with different stakeholders’ backgrounds.     

Estimating stranded coal assets in China's power sector

China has suffered overcapacity in coal power since 2016. With growing electricity demand and an economic crisis due to the Covid-19 pandemic, China faces a dilemma between easing restrictive policies for short-term growth in coal-fired power production and keeping restrictions in place for long-term sustainability. In this paper, we measure the risks faced by China's coal power units to become stranded in the next decade and estimate the associated economic costs for different shareholders. By implementing restrictive policies on coal power expansion, China can avoid 90% of stranded coal assets by 2025.

华北矿业型城市长序列能源消费碳排放特征

区域视角的长序列能源消费碳排放特征研究对低碳减排政策的制定具有一定意义。针对中国地市级及以下尺度数据难以获取、统计标准存在差异、从时间长序列角度对矿业型城市能源消费碳排放的研究较少等问题,基于夜间灯光影像数据模拟估算了1995～2017年华北矿业型城市能源消费碳排放量,对矿业型城市进行多维研究,分析不同矿业型城市碳排放的差异性。结果表明:能源消费碳排放量较高的矿业型城市为成长型煤炭型、再生型铁矿型、成熟型铁矿型以及成熟型煤炭型中的张家口市、忻州市和赤峰市;强度效应是促使能源消费碳排放量与经济增长脱钩的重要手段,结合人口效应、规模效应的调控,通过科学的低碳减排政策,能够有效地控制能源消费碳排放量的增加,加快矿业型城市的经济转型。
