中期财务报告准则的比较研究

为提高上市公司会计信息质量，更好地保护投资者利益，2001年11月，财政部发布了《企业会计准则——中期财务报告》。鉴于美国是实行中期报告制度最早的国家，其制度也相对完善，本文拟将我国中期财务报准则同美国的相关准则及国际会计准则IAS34作粗浅的比较分析。通过比较分析，借鉴国外准则之长处，有利于推动我国中期报告理论和实务的发展。     

Management earnings forecasts and other forward-looking statements

We identify forward-looking statements (FLS) in firms’ disclosures to distinguish between “forecast-like” (quantitative statements about earnings) and “other”, or non-forecast-like, FLS.  We show that, like earnings forecasts, other FLS generate significant investor and analyst responses. Unlike earnings forecasts, other FLS are issued more frequently when uncertainty is higher. We then show that earnings-related FLS are more sensitive to uncertainty than quantitative statements, suggesting that managers are more likely to alter the content than the form of FLS when uncertainty is higher.  Our study indicates that incorporating other FLS into empirical measures provides a more comprehensive proxy for firms’ voluntary disclosures.     

低碳经济发展中的碳排放驱动因素实证研究——以浙江省为例

本文基于三大产业和居民生活部门的12种能源消费量数据,较全面地测算了1995—2008年浙江省碳排放量,建立了碳排放驱动因素分解模型,将碳排放的驱动因素分解为能源强度、结构调整、经济发展和人口规模等四大类效应,并采用对数平均权重分解法(LMDI)测算了各类效应对碳排放量的贡献值、变化趋势及相互作用机理。研究结果表明,1995—2008年,浙江省碳排放量呈现不断上升的趋势;经济发展和人口规模对碳排放的正向驱动效应远超过能源强度和结构调整产生的负向驱动效应。本文同时测算出浙江已跨越了碳排放强度的高峰阶段,但仍处于碳排放强度高峰迈向人均碳排放量高峰的阶段。为缩短不同碳排放高峰的跨越时间,降低高峰峰值,本文提出了加快低碳经济发展的相关政策建议。     

How markets will drive the transition to a low carbon economy

This paper investigates the driving factors behind the transition to a low carbon economy. Here, we offer a two-part analysis: First, we examine the factors leading to the current level of cleantech development. To do so, we examine the impact of country-level economic variables (real GDP, market return, and turnover) and country-level institutional variables on patent intensity. Results from this analysis show that cleantech patenting activity is fostered by a supportive institutional environment that promotes innovation and low-carbon development through carbon pricing policies, country-level public R&D expenditure and human capital. Second, we extend the notion of ‘path creation’ to map out different pathways for cleantech development on a country-level within a real options framework, and offer a corresponding valuation of cleantech patents. Our estimates of total wealth creation through the development of cleantech patents by 2050 range from US$10.16 to US$15.49 trillion dollars (13%–20% of the world GDP in 2017) with investment growth from US$2.93 to US$3.71 trillion (3.7%–4.7% of the world GDP in 2017). The results from our analysis suggest that market forces will drive the transition to a cleantech economy.     

What Drives Quality of Firm Risk Disclosure? : The Impact of a National Disclosure Standard and Reporting Incentives under IFRS

This paper examines the impact of a detailed national disclosure standard on the quality of firms' overall risk reviews under IFRS. We use data from a sample of listed Finnish firms around the introduction of the standard and find that national regulatory bodies have been able to raise the quality of risk disclosure on several dimensions even under IFRS. We find increases in the quantity of risk disclosure with more extensive and more comprehensive information. We do not, however, find a corresponding increase in quantitative disclosures and therefore there is some question regarding the influence of the standard on the substance of the risk information provided. In addition to the coercive effect of the standard, several important reporting incentives, such as firm size, profitability, and foreign listing status are documented. We also find some evidence that the impact of the standard on quality is more pronounced among less profitable firms. Additional findings are that larger firms and firms reporting under the requirements of the SEC disclose more quantitative risk information, and that the quality improvements are permanent in the subsequent years. The findings have implications for standard-setters evaluating different strategies with the aim to increase the quality of the narratives in annual reports.     

中部六省碳排放效率与产业结构优化的耦合协调度及影响因素分析

采用SBM-Undesirable模型测算了1999—2017年中部六省的碳排放效率,分别计算了产业结构合理化指数和高级化指数,利用耦合协调模型考察了碳排放效率与产业结构优化的耦合协调度,并对其影响因素进行了实证分析。结果表明:中部六省碳排放效率和产业结构合理化的耦合协调度较低,处在中度失调和中度协调之间,碳排放效率和产业结构高级化的耦合协调度处在中度失调和中度协调之间,但有明显上升的趋势。人力资本、财政支出对中部六省碳排放效率和产业结构合理化的协调发展起到了促进作用,而环境规制、能源结构产生了抑制的作用。人力资本对碳排放效率和产业结构高级化的耦合协调度有正向作用,而外商投资、人均资本、制度质量和能源结构产生了抑制作用。     

中国中部六省的碳排放趋势研究

采用王铮等人提出的中国碳排放预估模型,测算在经济平稳增长条件下,中部六省未来的能源碳排放趋势,考虑了6省未来水泥工业的碳排放,并采用CO2FIX模型计算各省森林碳汇量,从而得出各省的净碳排放量,为各省制定碳排放战略提供参考。结果显示：各省的能源碳排放量都呈现先增长后下降的倒U型特征,能源碳排放高峰出现的先后顺序分别是河南、湖南、山西、安徽、江西、湖北;6个省份水泥工业的碳排放都呈现不断增长的趋势,水泥工业产生的碳排放量最大的是河南,最小的是山西;累计森林碳汇量最大的是江西省,其次是湖南省,河南省最小;各省应在减少能源碳排放的同时,控制水泥工业产生的碳排放,积极增加森林碳汇,从多方入手减少碳排放。     

碳排放交易的经济学分析及应对思路

在全球范围内,碳排放交易日益活跃。碳排放交易有着深刻的产权经济学内涵,是一种交易成本最小化的制度安排,是市场化的减污手段。在碳排放问题上,西方国家经历了从行政手段的庇古税到经济手段的排放权交易的演变过程。碳排放交易品种较多,构成了一个较为完整的产品体系。金融危机后,碳排放交易呈现出特定的发展趋势。我国需要进一步探索和发展碳排放交易市场,走好低碳经济时代的增长之路。     

气候变化背景下发展中国家的低碳经济发展

面对气候变化对人类发展的挑战,没有哪个国家能够独善其身,也没有哪个国家能够独立应对,而且气候变化对发展中国家的冲击比发达国家更甚。因此发展低碳经济是发展中国家的必由之路。由于技术和资金缺乏是制约发展中国家经济转型的最大障碍,所以文章侧重分析了如何在国际合作框架下实现低碳技术转移和解决资金瓶颈问题。
