Although there have been many studies on the degree of overfertilization, there are few systematic comparative analyses on the degree of overfertilization of three major grain crops (wheat, rice, and maize) over a long time span in recent years. Whereas the studies of the influence of government efforts, individual characteristics of farmers, and economic factors on farmer’s fertilization decision ignored the financial consideration of farmers. This study aims to systematically investigate the degree of overfertilization in the production of three major grain crops in 21 provinces of China from 2004 to 2018 by developing a panel-data model, and explores the impact of financial factors on overfertilization by applying Arellano-Bover/Blundell-Bond linear dynamic panel-data estimation. The results showed an upward trend in overfertilization in the production of three grain crops from 2010 to 2018, although a decline between 2007 and 2009 may indicate that the financial crisis had a short-term impact on overfertilization. Overfertilization varied across regions, and chemical fertilizers were applied most excessively in wheat production in the Huang-Huai-Hai region and in maize in Southwest China. The analysis of financial factors showed that cash earnings from wheat and maize positively affected overfertilization, whereas cash cost and farmers’ income had opposite effects. In fact, farmers value cash earnings and cash costs rather than the time value of money. In addition, the sensitivity and cautiousness of farmers regarding economic events may indicate that farmers have a certain degree of economic rationality regarding fertilizer input in several provinces, such as Anhui and Yunnan. The study provides necessary supplements to existing research on the influence factors of overfertilization and has implications for improving the design of fertilizer sales collection methods by the government and the financial service sector.

This study investigates all sustainability reports published between 2012 and 2016 by China’s Higher Education Institutions (HEIs). The aim of this paper is to investigate the characteristics of SR by China's HEIs and what causes these traits. After theoretical frameworks are described, the general situation of Sustainability Reporting (SR) in China’s HEIs is outlined. Then, an assessment framework is constructed which is a modification of the Global Reporting Initiative (GRI) Sustainability Guidelines for use in HEIs, and the content analysis method is applied to analyze and assess the extent of reporting of various items of SR in China’s HEIs. Finally, this study outlined the characteristics of SR by China’s HEIs and addressed their causes. The findings show that SR by China’s HEIs is still in the initial stage in terms of not only the relative share of China’s HEIs releasing sustainability reports but also the establishment of SR standards and the reporting level; has an obvious regional characteristic; and is under the control of Chinese government. The results of the theoretical analysis show that these characteristics may be due to the lack of internal dynamics and insufficient external binding force. Furthermore, we conclude that SR by China’s HEIs is a government-led activity, and essentially it is determined by the administration-based education system. Also, the practice of the Shanghai government demonstrates an important leading and stimulating role played by the government in promoting SR by HEIs. We argue that the Chinese mode has a certain value and practical implications for many countries. The study provides necessary supplements to existing researches through identifying and exploring a different development mode of SR by HEIs.

The total grid-connected installed capacity of wind power in northwest China has grown from 16,260 MW in 2013 to 43,290 MW in 2016; an increase of 88.7% each year. However, this region has suffered from increasingly serious wind curtailment since 2014, and the wind curtailment amount accounts for nearly a half of China’s total. The wind curtailment rate of Gansu Province, Xinjiang Uygur Autonomous Region and Ningxia Hui Autonomous Region in this area has increased and remains high. This paper constructs an analytical model to explore the reasons of the high wind curtailment of these three provinces from the four aspects of the wind power supply capacity, demand, grid transmission capacity, power system flexibility and market mechanism and laws. The results show that the relationship between the wind energy distribution and supply and the local load is incompatible, which is the source causing the high wind curtailment in northwest China. On the one hand, the game between the local government and developers has driven the development of wind power bases. On the other hand, the electricity sector is growing slowly and oversupply of electricity is seen in many areas of China. The wind power grid of northwest China not only faces limit of grid transmission capacity, but also constraint of insufficient flexibility of the electricity system. Presently, China has not set up a market mechanism and subsidy mechanism for the peak load adjustment, thus the thermal power companies lack motivation to voluntarily adjust the peak load. Moreover, the regional segregation and market barriers are also obstacles for the wind power outward transmission.

In China, due to forest resource scarcity, the problem of timber supply shortage has been around for a long time. The recycling and utilization of tree residues may effectively alleviate the situation and will contribute to emissions reduction and environmental protection. Therefore, this study aims to identify the tree residue resources and estimates their quantity in order to provide a basis for related research, such as its comprehensive utilization. This study redefines and reclassifies tree residue resources, in particular, it adds three tree residue resources: tree seedling residue, sanitation felling residue and urban greening and trimmings. This study divides the forest final felling and bucking residue resource into the stumpage section and the non-stumpage section, respectively, scientifically selects values of the percent of merchantable volume and the proportion of non-stumpage biomass of the stumpage volume, separately estimates the quantity of bamboo felling, bucking and processing residues, classifies the forest product processing zone into the sawing section and the forest product processing section, and estimates the current waste wood recycling quantity by tracking the timber output of previous years. The estimation results for tree residue quantity indicate that China’s tree residue reached 511.63 Mt in 2015, of which the forest tending and thinning residue was 406.76 Mt, nearly four-fifths of the total tree residue. Among the 31 provinces (municipalities and autonomous regions), more than half (55.57%) of the potential reserve of tree residues is distributed in the 13 provinces of southern China, 25% in the 10 provinces in the north, and approximately 20% in the plain and hilly areas. During the 12th Five-Year Plan period, the tree residue reserves showed positive growth. In the past three years (2014–2016), all state-owned forestry farms and collective-owned natural forests stopped commercial felling gradually, which directly resulted in a reduction of log output, thereby also curbing the growth of tree residue to a certain extent. Since the log output has ceased to further decline from 2017, it is predicted that China’s tree residue will continue the upward trend.

The clean development of China’s power supply structure has become a crucial strategic problem for the low-carbon, green development of Chinese society. Considering the subsistent developments of optimized allocation of energy resources and efficient utilization, the urgent need to solve environmental pollution, and the continuously promoted power market-oriented reform, further study of China’s power structure clean development has certain theoretical value. Based on the data analysis, this paper analyzes the key factors that influence the evolution process of the structure with the help of system dynamics theory and carries out comprehensive assessments after the construction of the structure evaluation system. Additionally, a forecasting model of the power supply structure development based on the Vector Autoregressive Model (VAR) has been put forward to forecast the future structure. Through the research of policy review and scenario analysis, the paths and directions of structure optimization are proposed. In this paper, the system dynamics, vector autoregressive model (VAR), policy mining, and scenario analysis methods are combined to systematically demonstrate the evolution of China’s power structure, and predict the future direction of development. This research may provide a methodological and practical reference for the analysis of China’s power supply structure optimization development and for theoretical studies.
