基于投影模型的不确定语言型多属性决策方法及应用

研究了不确定语言型多属性决策评价结果与决策者对方案的偏好信息之间存在偏差的问题,提出了基于投影模型的不确定多属性决策方法。该方法通过建立与区间型语言标度对应的术语指标矩阵,及方案综合属性值与决策者主观偏好值之间的投影模型,确定属性的权重,然后运用加权法得到方案的综合属性值,利用已有的可能度矩阵排序公式得到决策方案的排序。最后,通过算例对该方法的实用性和有效性进行了说明。

中国农村土地制度变迁:一个产权的视角

农地制度历来是中国农村变革的关键,其要义在于产权。本文从产权角度对建国后中国农地制度变迁作了简要分析。作者认为,产权的界定与实施决定着产权的经济绩效。土地改革以来各种农地制度创新形式的不同经济绩效都与产权清晰程度和实施机制有关。     

行为决策理论及决策行为实证研究方法探讨

作者对行为决策理论发展的历程及各阶段中决策行为的实证研究方法进行了梳理,发现决策行为的实证研究方法在很大程度上决定了行为决策理论发展的进程。在对决策行为一般实证研究方法及其特点进行分析之后,作者认为观察法较适用于决策行为的初步探索性研究;调查法则较适用于一般决策行为的总体状况和特征的研究;如果理论假说源于决策者某些特定的、深层次的主观动机,假设的证实或者证伪又需要大量的检验,实验法的优势比较明显。为了取得对本研究的实证效果,这里对如何将实验法应用于中国投资者决策行为研究做了一次实证性尝试,以供学术争鸣。     

PRICES AND PRICE ANALYSIS IN THE FRAMEWORK OF THE NATIONAL ACCOUNTS

The paper discusses the role of prices in the framework of the new System of National Accounts (SNA) in terms of three major uses: (1) deflation, (2) price indicators, and (3) price analysis. Following a brief review of the price and quantity measures required by the new SNA with its emphasis on deflation of commodity flows and input-output accounts, in addition to the more conventional deflation of final demand categories, the paper discusses some of the conceptual, methodological and data problems involved in implementing the various uses of prices in the new SNA. Implementing the use of prices as deflators depends, in part, on the concept of output selected (national versus domestic; gross versus net), and which of six concepts of valuation, ranging from purchasers'value to true factor cost, is used. Some of the difficulties in deflating nonmarket flows (e.g., interplant transfers) and industry value added, based on the double deflation method, are discussed. In concept price deflators, which have shifting weights, cannot be used as price indicators, which should have fixed weights. In practice, this is often disregarded and the deflators are used as price indicators. The paper support the SNA recommendation for the development of price indexes with fixed weights to be used as price indicators, in addition to the implicit price deflators. Research in the United States indicates that differences in weights can result in different price measures for various subperiods, components of demand and sector output. Periodic revisions in weights to provide more current fixed weights for price and quantity indexes in each subperiod may minimize the problem but it introduces a new problem—lack of comparability with the constant price tables in the SNA which have fixed weights for the entire period. The new SNA provides a comprehensive and integrated framework for price analysis including the analysis of the structure of aggregate price changes, the industrial origin of final demand prices, and the impact of price change in one sector of the economy on the rest of the economy. Some major gaps which need to be overcome in order to implement the use of the new SNA for price analysis include the development of industry capital stock estimates, separate estimates of proprietors’income, reconciliation of value added and distribution share estimates, and the development of a wide variety of information to supplement the conventional input-output tables in the SNA. Implementing the various objectives of price measures within the framework of the accounts will require a number of improvements in existing price measures and expanding the scope of coverage. “List” prices should be superseded by “transactions” prices and better techniques and data need to be developed to provide for quality adjustment of prices. Coverage will need to be expanded to include services, freight rates, trade margins, government expenditures, and also fill in gaps for many manufactured products. Finally, where possible, use of unit values as price indexes or deflators, e.g., imports and exports, should be replaced by direct price measures.     

许宁宁谈《服务贸易协议》

2007年1月，东盟系列峰会和东亚峰会在菲律宾第二大城市宿务举行，会议取得了丰硕成果。对内，东盟在加强组织机构、确定远景目标和解决共同关注的一些地区问题上取得了重要进展；对外，东盟与各对话国在政治、经济、社会文化等方面的合作更加深入、广泛和务实。具体到中国-东盟自由贸易区的建设，更是取得了重要突破，双方签署了中国-东盟自由贸易区《服务贸易协议》，标志着中国-东盟自贸区的建设向前迈出关键一步，为如期全面建成自由贸易区奠定了基础。会议刚刚结束，被媒体称为“中国-东盟首席商务专家”的中国-东盟商务理事会中方秘书处副秘书长许宁宁教授就接受了本刊的采访，他表示：“《服务贸易协议》的签署，对中国-东盟自由贸易区的建设起到了极大的推动作用。”[编者按]
