构建会计计量准则若干问题探讨

现行财务会计模式是以历史成本会计计量为特征的,会计计量问题没有引起会计理论界和会计准则制定机构的重视。我国新颁布的《企业会计准则》即将实施,虽然与国际惯例实现了趋同,但还存在缺陷。本文就制订我国会计计量准则提出建议。     

我国服务业增加值的核算问题

本文集中讨论我国服务业增加值估算中存在的问题。由于历史原因和服务业本身的一些特点 ,我国现价服务业增加值被严重地低估了 ,服务业增长率计算也可能存在着偏差。对服务业增加值的以往研究均受到基础数据的限制而未能根本地解决这些问题。服务业统计核算的缺陷严重地阻碍着经济分析和经济决策。因此 ,改善我国服务业统计核算是当务之急。从长远的角度来说 ,服务业增加值核算的改善在很大程度上取决于统计调查的完善。但是 ,在现有的条件下 ,仍然有很大的改善余地。

我国海洋养殖资源资产流失量价值模型构建

海洋养殖资源资产的流失已成为制约养殖业发展的重要因素之一。本文通过对养殖资源及养殖资源资产流失的界定,在资源所有者的所有权受损和海域低效利用基础上提出流失量价值即为海洋养殖资源资产价值与国家养殖资源资产总收益的差值,并将海水资源价值、环境成本价值和养殖成本价值作为养殖资源资产的总价值。

Review of tourism resources valuation

Tourism resources valuation is now a hot issue of the science of tourism resources, resources economics and environmental economics. This paper reviews research progresss on tourism resources valuation, introduces its theoretic basis, and elaborates two classical valuation methods： TCM and CVM. And two existing problems are discussed Firstly, tourism resources value constitution system is still under dispute. This paper puts forward the Value constitution system based on present value categories. Secondly, tourism resources valuation methods need further studies because both TCM and CVM have deficiencies. Finally, the paper points out the development direction of tourism resources valuation.     

Integrating ecosystem services into conservation assessments: A review

A call has been made for conservation planners to include ecosystem services into their assessments of conservation priority areas. The need to develop an integrated approach to meeting different conservation objectives and a shift in focus towards human wellbeing are some of the motivations behind this call. There is currently no widely accepted approach to planning for ecosystem services. This study contributes towards the development of this approach through a review of conservation assessments and the extent to which they include ecosystem services. Of the 476 conservation assessments identified by a set of search terms on the Web of Science, 100 were randomly selected for this review. Of these only seven had included ecosystem services, while another 13 had referred to ecosystem services as a rationale for conservation without including them in the assessment. The majority of assessments were based on biodiversity pattern data while 19 used data on ecological processes. A total of 11 of these 19 assessments used processes, which could be linked to services. Ecosystem services have witnessed an increase in attention received in conservation assessments since the year 2000, however trends were not apparent beyond this date. In order to assess which types of ecosystem services and how they have been accounted for in conservation assessments, we extended our review to include an additional nine conservation assessments which included ecosystem services. The majority included cultural ecosystem services, followed by regulatory, provisioning and supporting services respectively. We conclude with an analysis of the constraints and opportunities for the integration of ecosystem services into conservation assessments and highlight the urgent need for an appropriate framework for planning for ecosystem services.

The measurement and decomposition of nonuse values: A critical review

We critically review the literature that claims that existence values, or nonuse values in general, are a large and measurable component of total value for certain environmental resources. Our concern is not with the question “do nonuse values exist?” For some individuals they surely do. Rather, our concern is with two interrelated questions: are there operationally meaningful theorems which might lead to the specific measurement of nonuse values, and do we in fact have a body of credible evidence which shows that nonuse values, particularly components of any nonuse value, are “large”? We find nothing in the way of operationally meaningful hypotheses which would permit the estimation of values attributable to specific motives of individuals. We find no credible basis for claims related to either the measurement of existence and other motive-related values or claims for the “large” relative size of such values. In short, we question the conventional wisdom that such values are measurable and that they are significant as a component of total value.
