Influence mechanism of government subsidy on the green transformation of coal company in China

The optimization of government subsidies to enhance the efficiency of coal companies’green transformation constitutes a critical component in the pursuit of global sustainability.We investigate the influence mechanism of government subsidies on the green transformation using data from the listed coal companies in China from 2007 to 2022.According to our findings and hypothesis testing,previous government subsidies did not have a significant direct impact on coal companies’green transformation.Nevertheless,government subsidies can help coal companies transition to greener practices by promoting innovative green initiatives.Furthermore,we confirmed an indirect route:that government subsidies enable the adoption of low-carbon initiatives,which in turn could facilitate the transition of coal companies towards green practices.In addition,we discovered that the coal company’s digitization will improve this indirect route.Thus,we propose increasing the effectiveness of government subsidies in facilitating coal companies’transition to green practices by focusing on technological advancements and enhancing company digitalization.

The Implementation Mechanism of SocialResponsibility in Chinese State-ownedCompanies

The concept of corporate social responsibility was origined in the United States in the early 1990 s. This theory is put forward,and quickly caused the widespread attention of various disciplines. With the transition of the planned economy to marketeconomy in our country, most of the enterprises in China will still refuse to take care of the social responsibility and a series ofproblems become the biggest contradiction in China＇s economic development and social development. So it is necessary forChina to slove these problems.

Coal price fluctuations and the impact on financial risk Evidence from China＇s coal listed companies

With the rise of coal price, the proportion of loss-making enterprises shows an upward trend in China＇s coal industry. This paper uses Altman Z-Score model to measure financial risk of 19 listed companies in the coal industry in A-share market from 1995 to 2007. Empirical results show that Year-Based price index of coal price has a negative correlation with the financial risk but has no significance, and coal chain price has a significant negative correlation with the financial risk. Further research indicates that enterprises increase bad investment, and a lot of debts caused by short-term rise in coal prices. The results also show that the financial risk in the coal industry declines with the rise of GDP growth rate and increases with the rise of inflation rate.

考虑多市场价格与碳核查不确定性的发电企业交易策略

随着中国“碳达峰·碳中和”战略的提出,发电企业不仅需要参与电能量和煤炭市场交易,还需根据实际碳排放水平参与碳市场交易。然而,由于电-碳-煤多市场间存在交易规则不同、交易时序异步、交易随机要素多元等特点,发电企业面向单一市场的传统交易策略难以适用,亟需一种考虑多元随机性的多市场协同交易策略。文中考虑多市场价格风险和碳市场核查的不确定性,提出了发电企业电-碳-煤中长期滚动交易决策模型。该模型首先基于年前预测价格决策年度合约电量和年度购煤量;然后,根据每月最新价格预测,滚动优化年度剩余月份的月度合约电量、月度购煤量以及碳配额交易量;最后,以燃煤发电企业为研究对象进行算例分析,分为碳买方和碳卖方两个基础场景进行比较研究。结果表明,所提模型能够为发电企业在电-碳-煤多市场中的交易提供策略指导,在发电企业作为碳买方和碳卖方的场景下,分别提高了约7.6%和6.4%的企业总利润。

铁路与矿业:道清铁路与中福联合办事处的成立与整理(1928—1936年)

道清铁路以运输豫北矿产为主,这使得其很容易成为豫北矿业行业竞争的牺牲品。从福公司撤离至中福联合办事处成立前,道清铁路运营管理权被一矿独大的中原煤矿公司控制。借助国民政府加强对全国铁路集权化管理的机会,道清铁路试图摆脱被豫北矿业长期控制的局面。因得不到道清铁路配合,中原煤矿公司难以阻止福公司的复工。在国民政府的干预下,两公司被迫重组成为中福联合办事处。因道清铁路的钳制,中福联合办事处的成立并没有改善豫北矿业糟糕的现状。在国民政府决议全面整理中福联合办事处的高压下,道清铁路不得不最终屈服。道清铁路与矿业之间的矛盾并非单纯的路矿业务纠纷,还与政治外交、矿业政策的调整等各方面牵扯在一起。道清铁路最终成为国民政府与英国外交博弈、矿业政策调整的工具。路矿纷争及由此引起的政治外交和矿业政策等方面都成为制约道清铁路运营发展的重要因素。透过道清铁路与豫北矿业的关系互动,从一个侧面反映了近代铁路运营发展的艰巨性。

Restructuring in China's State-owned Enterprises:Evidence from the Coal Industry

Usingfirm-level data for China ＂s state-owned coal mines, this paper examines the impact of privatization, corporatization and debt restructuring of state-owned enterprises on technical efficiency. A stochastic frontier production method is applied to a panel dataset from 2000 to 2007. The simultaneous study of these three measures makes it possible to study individual effects more precisely than otherwise. The study shows that the three reform initiatives are all able to improve technical efficiency in state-owned coal mines. The finding of a significant efficiency improvement from relinquishing state ownership provides an alternative to privatization. The study of debt restructuring and technical efficiency has not been documented in the published literature.
