中国东部特大都市圈产业结构趋同的FUZZY分析

地区产业结构是某地区各产业生产能力的配置构成的方式。以往采用不同指标对产业结构趋同化加以分析,做出的判断有较大差异。而比较优势原理和分工理论才是判断地区产业结构是否趋同的根本依据。分析地区产业结构趋同问题必须首先分析资源状况,在判断资源状况是否相似的基础上再来判断产业结构是否趋同。文章通过引进模糊数学的聚类分析方法,对东部三大都市圈的资源状况和产业结构进行了聚类分析,用科学而直观的方法得出了中国东部特大都市圈产业结构趋同的结论,并分析了产业结构趋同的形成原因,同时指出只有进一步建立和完善社会主义市场经济体制,确立企业的市场主体地位,转变政府职能,提高国家对宏观经济调控的有效性,才能使地区产业结构趋于合理化。

China's patterns of international technological collaboration 1976–2010: a patent analysis study

This study focuses on the trajectories and patterns of China's international collaborations over the period 1976–2010, using patent statistics and association analysis methods. The results identify those government policies that have significantly encouraged changes in the scale and scope of China's collaborations since 1997. The USA and Taiwan are major international collaborators with China, and the top cooperative entities are large-scale multi-national firms, which specialise in production, sales research and development of information or electronics technology; in contrast, universities and research institutions have a negligible presence in international collaborative patenting. This study finds that although China has developed significant international collaborative networks since the 1990s, it still needs to extend these ties to an even greater range of international partners and establish a broader scope of research interests.     

A systematic approach for integrated trend analysis—The case of etching

Understanding technology development trends is of critical importance to countries, industries and enterprises to be sustainable in global competition. Attempts have been made to establish trend analysis by bibliometric and patent analyses. Also text-mining uncovers hidden and important information from structured or unstructured documents which serve as knowledge carriers. This study aims to provide a systematic approach for integrated trend analysis that takes into account bibliometric analysis, patent analysis and text-mining analysis. Etching is selected as the case study for integrating trend analysis method proposed in this study. Also, validity and applicability of the integrated analysis are evaluated.

制度分析是当代社会科学领域一个重要的理论分析工具。20世纪70年代以来,经济学、政治学等重新发现了制度对解释现实问题的重要性,形成了新制度主义的制度分析范式。基于共同的逻辑起点、行为假设和理论工具,制度分析范式形成了不同的制度分析途径,如嵌入性制度分析、立宪制度分析、比较制度分析、历史制度分析和多中心制度分析等。制度分析拓展了社会科学的研究对象,增强了社会科学解释和解决现实问题的能力,越来越多的领域被囊括到制度分析中。     

Applying input-output analysis to scenario analysis of ecological footprints

Application of input-output analysis to ecological footprints (EFs) is shifting from an ex-post static calculation toward an ex-ante scenario analysis for enhancing the policy relevance of EF analysis. This change in application prompts two issues requiring careful examination: (1) what is measured by Leontief inverses or extended environmental Leontief inverses, and (2) whether a sector's land multiplier (or compositions of land multiplier) can appropriately reflect the effect of delivering one unit of the sector's output to final demand on the required area(s) of production lands used by the sector itself and by other producing sectors whose products are contributed directly and indirectly to its production. The underlying message of these two questions is whether the assumed linear marginal relationship between a sector's output and its intermediate inputs (input-output coefficients)—a critical assumption made by W. Leontief to transform a transactions table from an accounting framework into the input-output model—can be extended to assume that the marginal relationship between a sector's output and the area of production land it uses for generating output is fixed (land-output marginal coefficient equal to average coefficient). By reviewing the literature on input-output analysis and its application to environmental issues and by theoretically and empirically examining the relation between sector output and land appropriation, this study advises against the use of land multipliers or their compositions in the EF scenario analysis.To apply the input-output model to EF scenario analysis for enhancing policy relevance with due attention to the relationship between sector output and land appropriation, this study suggests a two-stage EF calculation procedure. In the first stage, the input-output application estimates only the required raw materials (or generated pollutants) for meeting a given consumption pattern, which is the objective of environmental input-output analysis; in the second stage, the estimated amount of raw materials or pollutants is converted into land/water area, and a choice of conversion methods is suggested according to the research questions and the availability of conversion methods and required data.     

Adherence to guidelines for sensitivity analysis: cost-effectiveness analyses of dual oral antiplatelet therapy

Abstract

Objective: Cost-effectiveness analyses of new treatments for cardiovascular disease frequently require input parameters whose values are known with uncertainty due to limited data. The objective of this paper is to examine the extent to which published sensitivity analyses addressing this uncertainty adhere to Health Technology Assessment (HTA) guidelines.

Research design and methods: A systematic review of published cost-effectiveness analyses was performed for an example drug treatment scenario, dual oral antiplatelet therapy compared with aspirin alone following acute coronary syndromes and/or percutaneous coronary intervention. The following medical literature databases were searched for articles published from January 1997 to June 2007: PubMed, Cochrane Collaboration, EMBASE and the Health Economic Evaluation Database (HEED). Evidence tables were created to show the sensitivity of the cost-effectiveness estimates to changes in the input parameter values, as well as the data sources used for the reference-case and sensitivity analysis input parameter values. The extent to which the sensitivity analyses adhered to HTA guidelines were also examined.

Results: Cost-effectiveness ratios were most sensitive to changes in the efficacy of dual antiplatelet therapy and reference-case model assumptions about costs beyond the trial period. Although alternative values tested in the sensitivity analysis for some input parameters were based on observed ranges or distributions, alternative values tested for many other input parameters were assumed without justification.

Conclusions: Sensitivity analyses in the cost-effectiveness studies of dual oral antiplatelet therapy were not fully adherent with HTA guidelines. In particular, long-term costs and benefits were not always included in the sensitivity estimates, the impact of differential effects on death and myocardial infarction was not explored, and justification for the alternative parameter values tested was not always provided.     

Patent text mining and informetric-based patent technology morphological analysis: an empirical study

Patent technology morphological analysis utilises the advantages of both patent information analysis and morphological analysis to provide more detailed information on current and future patent technology. Current patent technology morphological analysis methods are largely reliant on manual expertise in the construction of morphological boxes with few approaches to the evaluation of future morphological configurations. We developed a patent text mining and informetric-based patent technology morphological analysis technique. We defined the basic parameters of the morphological box as the factors in factor analysis, with a patent keywords matrix, and the clusters in clustering analysis with factor scores. Patent citation, year of patent registration, keyword frequency, and contributing factors were used to evaluate future morphological configurations. We used an empirical study of liquid crystal display wide viewing angle patents to validate our method. The Thomson Reuters Derwent Innovation Index was used to collect patent text datasets. Our study indicates that this method is feasible for the implementation of patent technology morphological analysis. Our method provides advantages in terms of cost and time reductions during morphological box construction and more flexible methods for evaluating morphological configurations. We discuss problems and possible development of our method in the last section.
