基于关联规则与信息熵的技术融合趋势研究

根据从德温特专利数据库中检索的专利数据,运用Apriori关联规则算法得到关于技术融合趋势的关联规则,然后通过基于差异思想的兴趣度模型验证规则的有效性,并在关联规则基础上利用信息熵评估企业核心技术领域分布及变化情况。最后,以安川电机和发那科公司为例进行实证分析。研究结果显示,基于差异思想的兴趣度模型弥补了关联规则因阈值设置主观性较强而导致部分规则无效的问题。     

GVC下中国装备制造业与生产性服务业融合影响因素研究

基于全球价值链（GVC）视角,应用质化研究方法中的扎根理论,系统研究了中国装备制造业与生产性服务业融合影响因素,基于大量访谈,从深层次视角揭示了GVC下两大产业融合影响机理。研究发现,融合意愿、融合能力、融合环境和融合资源是GVC下影响中国装备制造业与生产性服务业融合的4个主要因素。其中,融合意愿和融合能力是两大产业融合的直接影响因素,而融合环境和融合资源是间接影响因素。在此基础上,构建了涵盖子范畴（12个）、主范畴（产业融合意愿、能力、环境和资源）和核心范畴（产业融合）的影响因素模型。最后,提出创建产业融合平台和降低行业壁垒等促进GVC下两大产业融合发展的策略与建议。     

中国旅游增长收敛吗——基于1990～2008年入境旅游收敛性研究

旅游促进落后地区经济发展,为相对落后地区追赶发达地区贡献力量,国务院、旅游局等曾先后提出要＂促进区域旅游协调发展＂。这种区域旅游协调发展的思路有一定理论基础：从新古典经济学角度看,由于存在资本边际收益递减规律,落后地区会以较高的增长速度追赶发达地区,最后达到收敛的均衡状态;但是从空间经济学角度看,由于存在规模收益递增效应,会出现两极分化而不是收敛的结果。为检验我国旅游增长是哪一种结果,以我国1990～2008年入境旅游统计资料为依据,使用β无条件收敛和条件收敛检验了我国入境旅游收敛情况。结果表明,我国入境旅游以2%的速度无条件收敛,以8%的速度条件收敛。所以,我国入境旅游发展是资本边际收益递减规律起主导作用,即我国入境旅游增长存在收敛情况。此外,研究还发现：现实旅游资源、人力资本、感知距离等因素,能在不同程度上影响我国入境的旅游收敛情况。     

中国地区工业的生态效率测度及趋同分析：2003—2010年

生态效率兼顾经济活动的生态效益和经济效益,在一定程度上反映了经济可持续发展水平,其综合评价有助于探索经济发展方式转变的路径。2003—2010年中国大陆31个省份的工业生态效率测度及趋同分析表明：我国工业生态效率普遍偏低,其省际差异和年际变化差异都较大,而且存在明显的生态效率趋同。为进一步改善我国各省的工业生态效率,既要广泛搭建技术转移平台以促进先进技术推广,还要大力提高落后地区的技术能力以促进先进技术的充分吸收和利用。     

Asymmetric Behaviour of Spanish Regional House Prices

In connection with the housing market, which is presently raising a great deal of concern among the general public, this paper investigates regional housing prices in Spain using variable co-integration techniques. It analyzes the asymmetric behavior in real house prices among the Spanish regions focusing on the study of the long-term relationships over time. This paper raises an important question of the national averages masking important regional asymmetries. Results indicate evidence of co-integration, which suggests a broad grouping of regions based on physical proximity or similar economic characteristics.

Riding the US wave: spectrum auctions in the digital age

Given its significant technological advantages compared to analog broadcasting, digital television (DTV) will be the television system of the future. However, it requires a full replacement of analog television sets by digital receivers, as DTV can only be watched with special equipment. In order to make this transition happen smoothly without losing the analog television audience, both signals have to be simulcasted until a substantial coverage with DTV broadcasting has been achieved. Australia and the US meanwhile have established a regulatory framework to lead this transition towards the end of analog broadcasting, the so-called analog switch-off. Part of the US regime is the FCC's obligation to reassign analog frequencies after the switch-off has taken place by means of auction. Spectrum auctions, however, originate not from the US but from New Zealand, where they have been used since the end of 1989 and ever since been subject to legal and political criticism. The article outlines the principles of both the DTV and spectrum auctions regulation and shows the links between both areas of telecommunications regulation. It concludes by suggesting that the analog switch-off is a unique opportunity to reconsider current spectrum policies, as it frees large amounts of the radio spectrum that are today occupied by analog broadcasting and will soon be subject to one of the biggest frequency reassignment processes in the history of telecommunications regulation.     

Interpreting cross-section and time-series tests of convergence: the case of labor productivity in manufacturing

This paper investigates whether a disaggregated measure, labor productivity in manufacturing, is converging across eight OECD countries during the period 1950–1998 using both cross-section and time series tests of convergence. The evidence indicates convergence using either test for the full sample, but tests over subperiods suggest that the dynamics of the underlying series change from economies in transition in the early years to economies in balanced, but parallel, growth paths in the later period. The results confirm that the appropriate test for convergence depends on the underlying structure of the data.     

Coevolutionary cycles of convergence: An extrapolation from the ICT industry

Convergence between technologies can be regarded as an increasingly emerging trend, and has received particular attention in the coming-together of previously distinct products and solutions within the information and communication technologies (ICT) industry. In previous research, the overall impact of the convergence phenomenon remains ambiguous. Whereas some scholars suggest convergence to be associated with disintegration, entry and growth, others relate the phenomenon to opposite effects, such as consolidation and shakeouts. This inconsistency in managerial conceptions on convergence formulates a need for an integrated understanding. Within a multi-case study approach, the convergence within ICT has been observed through examining the coevolution of actors in a converging environment, and patterns in innovation dynamics and managerial responses have been identified. In reflection with existing models of innovation cycles, a model for convergence innovation processes is elaborated and discussed. In particular, the reasoning within the ICT case set is transferred onto the currently emerging entrepreneurial activities in the intersection between nano- and bio-technologies (NBT), resulting in a comparison between ICT and NBT convergences, and deriving recommendations from a retrospective to a predictive context.     

中国地区收入差距、全要素生产率及其收敛分析

本文在测算和分析1982—2002年省区全要素生产率(TFP)的基础上进行TFP的收敛检验,并与收入(劳均GDP)的收敛模式做了对比分析。分析表明TFP解释了我国省区收入差距的主要部分;我们应用OLS、PanelData固定效应估计方法和DynamicPanelData(一阶差分GMM)方法进行收敛检验,得出的结论是:TFP与收入的收敛模式具有很大的相似性,全国范围内没有绝对收敛,只有条件收敛,但是TFP的收敛速度明显高于收入的收敛速度。三大地区中只有东部地区存在俱乐部收敛现象。而且,我国TFP与收入的收敛模式与世界范围的TFP和收入的收敛模式具有很大的相似性。     

公司治理、会计环境与会计准则国际趋同

本文分析了公司治理、会计环境与会计准则国际趋同的内在关系,认为会计准则国际趋同的实现有赖于完善的公司治理与相关的会计环境适应机制。会计准则国际趋同的实现也会推动公司治理的完善,并为保证会计准则国际趋同有效实行提供了新思路。
