上市公司房地产开发业务会计核算问题探讨

笔者在对年报事后审核过程中发现,上市公司对房地产业务的核算存在不少问题。如对收入的确认没有完全按照《企业会计准则——收入》的要求进行确认;对预收的售房款应交纳的营业税和所得税计算不正确;对房地产开发业务所涉及的土地和房产的成本计算不规范;对房地产开发业务所涉及[是公司管理层认为截至1999年12月31日,房地产项目已开发完毕,并通过工程竣工验收,公司已就上述楼盘的房屋与购买方签订了销售合同,坚持认为应该确认该部分房屋收入;而注册会计师认为,公司虽就上述楼盘的部分房屋与购买业主签订了销售合同,但尚未办完业主入住手续,…     

The Effect of Ultimate Ownership on the Disclosure of Environmental Information

This study empirically examines whether environmental information disclosure (EID) is influenced by the characteristics of a firm's ultimate owners. Based on the EID of publicly listed firms in China, we qualitatively measure the quality of EID of each firm and link those quality scores to firm characteristics to understand the determinants of EID. We further link the EID scores to market valuation of the firm through the Ohlson valuation model to understand whether the market appreciates EID. Our results show that EID is more likely for government‐controlled firms, firms with less hierarchy in their ultimate ownership and firms with more discrepancy between voting rights and cash flow rights. Our results also indicate that the stock market appreciates environmental issues and that EID itself, as well as disclosure quality, is associated with a higher market valuation. Our results still hold with the endogeneity issue controlled.     

Carbon Disclosure,Financial Transparency,and Agency Cost: Evidence from Chinese Manufacturing Listed Companies

Given the constraints on carbon emissions due to their impact on global warming, carbon disclosure has become an important way to deliver signals to the market. We examine the benefits associated with carbon disclosure from the standpoint of corporate social responsibility (CSR) for China’s manufacturing industries from 2010 to 2014. We divide corporations into heavily polluting and non-heavily polluting groups in order to control the industry factor. Based on the Principal-Agent Theory, we empirically test the relationship between carbon disclosure and financial transparency, and we evaluate the effect of carbon disclosure on agency costs and operations. Our results highlight that carbon disclosure is negatively associated with agency costs. However, we do not find enough evidence to prove what role financial transparency plays in the relationship between carbon disclosure and agency cost. Therefore, the influence of financial transparency as a mechanism is not yet clear. This study provides a way to look at the intentions of firms that disclose carbon information, and it also enhances the literature on carbon disclosure and agency costs in China based on Chinese data.     

A Dynamic Study on Ecological Disaster,Government Regulation,and Renewable Resources

This article develops a dynamic model to investigate renewable resource markets under different property rights. We find that different property rights regimes in renewable resource markets yield very different equilibria. Under private property rights, the valve point increases with the natural growth rate, productivity, number of firms, and marginal costs. Under common property rights, “the tragedy of the commons” inescapably occurs. This study suggests how to avoid ecological disaster by implementing a set of public policies.     

耦合多元价值的生态风景道规划研究 ——以乌兰察布四横交通带风景道为例

近年来随着中国对交通运输与旅游融合的重视，风景道的研究与建设被提上日程。基于对生态保护、特色景观与休闲游憩的多元需求，由国内对风景道的研究和一系列实例入手，在传统风景道概念的基础上提出建设居于多元价值的生态风景道。同时，以乌兰察布四横风景道的规划为例，研究了基于形态学空间格局分析的生态网络构建、景观视觉评价的景观节点建设及串联沿途旅游资源的绿道系统建设，在实践中探讨了多元价值目标导向下风景道规划设计的策略和方法。     

退社行为对合作社可持续发展的影响分析——来自渤海湾优势区211户退社果农的实证

基于目前合作社中存在的农户退社现象,本文利用211个有效样本实证分析了果农退社行为与果农合作社可持续发展的关系。研究发现:其一,从整体看,果农退社的四种方式均会对果农合作社可持续发展产生显著的负向影响,且负向影响程度由大到小依次为被迫退社、盲从退社、主动退社、隐形退社。其二,从细分维度看,一方面,主动退社、被迫退社和盲从退社会对合作社内部凝聚力、成员积极性产生负向影响,而隐形退社则对这二者无影响;另一方面,四种退社方式均会对合作社组织声誉、政府资源利用产生负向影响。其三,从发展水平看,果农退社方式对高水平果农合作社的可持续发展的负向影响程度相对轻微,且主动退社行为对高水平果农合作社的可持续发展具有显著的正向影响。其四,从比较分析看,果农退社方式对中、低发展水平合作社具有不同程度、不同方向的影响。本文研究结论对合作社管理者采取差异化措施防止退社现象蔓延、优化退社制度安排以及有效利用政府资源具有一定的启发。     

Credibility in Loss Reserving

This article proposes using credibility theory in the context of stochastic claims reserving. We consider the situation where an insurer has access to the claims experience of its peer competitors and has the potential to improve prediction of outstanding liabilities by incorporating information from other insurers. Based on the framework of Bayesian linear models, we show that the development factor in the classical chain-ladder setting has a credibility expression: a weighted average of the prior mean and the best estimate from the data. In the empirical analysis, we examine loss triangles for the line of commercial auto insurance from a portfolio of insurers in the United States. We employ hierarchical model for the specification of prior and show that prediction could be improved through borrowing strength among insurers based on a hold-out sample validation.     

基于BDS的ADS-B报文生成系统

目前国际民航组织（ICAO）和美国航空无线电技术委员会（RTCA）有关广播式自动相关监视（ADS-B）标准中的报文数据源均规定来自全球定位系统（GPS），而中国自主建设的“北斗”卫星导航系统（BDS）作为ADS-B数据源是必然趋势。设计了基于BDS的ADS-B报文生成系统的总体架构，利用BDS接收机接收的真实数据仿真生成了ADS-B的6种报文，并以空中位置报文的生成为例，详细阐述了报文产生涉及的关键技术以及报文的生成过程。通过运行集成后的ADS-B报文生成系统以及对所产生的6种报文的仿真验证，证明该系统总体设计思路合理，运行结果正确，可为基于BDS的ADS-B相关技术研究提供稳定可靠的ADS-B报文源。
