利用旅游收入统计测算旅游增加值的相关问题

利用旅游收入统计数据测算旅游增加值的方法简便易行,其内在原理是旅游收入的分项构成属于相应行业收入的一部分,因而可以用当年所在产业的增加值率计算旅游收入分项构成的增加值以后汇总。但公布该方法的原文提出＂旅游消费剥离系数＂只是为了试推算其他地区和年份的旅游增加值,这一系数的内在基础存在缺陷,原作中即有承认,不宜继续使用。国民经济行业分类标准在2002年修改以后,旅游收入分项测算旅游增加值的产业归类也相应调整。虽然旅游卫星账户测算旅游经济影响的技术更加全面准确,但由于其方法繁杂并需要区域投入产出核算为基础。在可预见的将来一段时间内,利用旅游收入统计数据测算旅游增加值的方法仍会继续使用。     

Nonparametric Estimation of Oligopsony Power in First‐Price Auction

This paper proposes a nonparametric procedure to estimate market power for first‐price auction data and applies the procedure to cattle procurement markets. Most previous studies have used parametric methods, which require specific functional forms for retail demand, input supply and processors’ cost equations. However, researchers often find that market power estimates from parametric methods are sensitive to the choice of functional forms and specifications. An application to data from cattle procurement experiments shows that our nonparametric approach greatly outperforms commonly used parametric methods in estimating the degree of market power. While parametric estimates are sensitive to functional form specification and are at least 90% smaller than ‘true’ market power indices, estimates from our nonparametric procedure deviate from the actual value by no more than 25%.     

直接测汞仪测定食品中鱼类、肉类和蛋类汞含量的不确定度评定

采用直接测汞仪测定罗非鱼、猪肉和鸡蛋,建立不确定度的数学模型,以此分析该方法不确定度的来源.通过对各分量的来源分析、计算和合成,结果表明,对样品中汞质量测定过程引入的不确定度贡献最大为标准曲线拟合过程,其次为储备液配制以及标准系列工作液配制,第三为重复性测定引入的不确定度;经过最终合成评定,罗非鱼中总汞结果可表示为(1...

多层介质频率选择表面的等效电路分析方法

基于数值仿真计算和微波网络理论,提出了一种多层介质中频率选择表面（FSS）等效电路的分析方法。该方法物理过程直观,计算量小,适用于二维任意形状FSS等效电路的精确求解。以方形贴片型FSS为例验证了等效电路模型的准确性,并分析了多层介质对其等效电路参数的影响规律。最后,基于滤波器理论与FSS等效电路模型设计了双层带通型FSS,计算结果表明全波仿真结果与理论计算结果基本一致,为多层FSS的综合设计提供了一种精确设计方法。     

Sustainability： Corporate Responsibility for the Future Classroom

The machinery, equipment, inventory, and other assets of the 21 st century company without people to work them. Corporations, by leave of the accounting profession, have no real economic value continue to omit the value of human. And yet, there is a growing realization that people represent the largest proportion of corporate productive capacity relative to the current assets and fixed assets shown in corporate financial statements. This paper provides research on the top 50 of the Fortune 500 companies which confirm this material deficiency. There is a need to provide stakeholders with a ＂fair＂ knowledge of the value of corporate human capital to provide a higher standard of transparency and accountability in international financial reporting and to provide the basis for research into the sustainability and potential expansion of growth in the world economy. An appropriate standard for the valuation of human capital will provide the knowledge base for effective and efficient investment in human capital. Effective and efficient investment will be particularly valuable for governments and service industries and for those who wish to promote growth in Europe. Indeed, the Organization for Economic Cooperation and Development （OECD） is questioning the veracity of financial statements which fail to include ＂the most valuable＂ of corporate assets in their financial statements. Recently, the OECD has noted that human capital may be measurable ＂by the output potential of specific competencies＂; ＂the fruits of （corporate） investment＂; the objective measurement of the market ＂rental＂ price of human capital; and lastly, perhaps self-evident when it comes to physical capital, the output potential of corporate investment in their human capital inventory. This paper considers the conditions in the context of literature which reassesses theory and assumptions which have been made on the valuation of human capital. Human capital is a pre-requisite for tangible assets to be productive. The valuation of human capital will trigger the same sort of activity-based analysis of people power as computers brought to cost accounting. The knowledge century analysis of people power will take off when human capital is at last included in the list of assets on the corporate balance sheet.
