Julia例外函数集的一些性质

本文从正规簇理论出发,证明了1919年由 Julia 定义的 Julia 例外函数,与1926年由 Ostrowski 定义的 Julia 例外函数的等价性,并用 Ostrowski 的定义,证明了 Julia 例外函数集 J,对普通函数的加法和乘法,构成一个交换域,并且 J 中一致球面收敛函数列的极限,也是 Julia 例外函数。     

我国省际产业集聚与经济收敛性特征及其相互关系的经验研究

采用变异系数和β收敛模型等经济敛散性度量工具,对1992～2004年期间我国省际经济收敛性的阶段性特征进行了定量分析和检验;采用产业集聚度指标和聚类分析方法对这段时期省际经济的产业集聚状况进行了详细分析;在此基础上,对产业集聚与经济收敛的关系,即产业集聚是否会影响到地区间经济差距的扩大与缩小以及影响程度如何进行了实证检验。结果表明,在1992～2004年间。我国省际之间经济存在先条件收敛、后绝对发散、再到敛散状况不明显三个阶段,并且其敛散性与产业集聚状况存在显著的相关关系;在不同的时期,产业集聚对区域经济敛散性的影响也不同。     

Does Convergence of Accounting Standards Lead to the Convergence of Accounting Practices?: A Study from China

In this empirical study we examine whether China's efforts to converge domestic accounting standards with International Financial Reporting Standards (IFRS) over the past 15 years have resulted in the successful convergence of Chinese listed firms. This study is unique in that we evaluate convergence of firms' accounting practices from three perspectives: (1) the level of compliance with Chinese GAAP and IFRS, (2) the consistency of accounting choices under Chinese GAAP and IFRS, and (3) identification of significant differences in the net incomes produced under Chinese GAAP and IFRS (earnings gap).Using the 1999 and 2002 annual reports of 79 Chinese listed firms we find improvement in both compliance with IFRS and in the consistency of the accounting methods used in annual reports prepared under Chinese GAAP and IFRS. We also find a reduction in the earnings gap from 1999 to 2002. However, interestingly we observed that Chinese listed firms' compliance with IFRS is significantly lower than their compliance with Chinese GAAP. Overall we believe that our findings suggest that in China the convergence of accounting standards has been a conduit to the convergence of accounting practices.     

中国各地区城乡收入收敛性实证研究

使用1991-2011年的人均收入和CPI数据,对中国东、中、西、东北部地区进行了β和σ收敛分析,实证表明:东部地区城镇、农村人均收入在1991-2011年不存在σ收敛、β收敛,即东部地区城镇、农村人均收入差距都在不断扩大;中部地区城镇、农村人均收入在1991-2011年均存在σ收敛、β收敛,且城镇人均收入每年以17.333%的速度收敛,农村人均收入每年以8.333%的速度收敛;东北地区城镇人均收入差距在不断扩大,而东北地区的农村收入每年以3.378%的速度收敛;西部地区城镇人均收入差距在缩小,每年以8.174%的速度趋于一致,而农村人均收入差距在不断扩大;中部地区人均收入在城镇、农村上收敛速度均为最大。     

福建省先进制造业R&D投入产出效率研究

首先对随机前沿函数的变量和形式加以确定。然后采用该函数和面板数据模型,研究了福建省先进制造业的R&D投入产出效率及其影响因素和收敛性。研究结果显示:R&D人员投入、R&D经费内部支出及新产品研发投入对新产品产值产出具有显著效应,其中R&D人员投入的正效应偏大;福建省高新技术产业R&D投入产出效率总体上居中,具有增长趋势和收敛性;九大行业样本期间的企业数量和政府资助对其R&D投入产出效率具有显著影响。最后针对研究中发现的问题,提出企业和政府对R&D发展应该采取的对策和解决措施。     

A new study of the Chinese regions in a neoclassical framework of models of growth

This study tests economic growth and convergence across the Chinese provinces during the period 1981–2005 based on augmented neoclassical growth models where land is included as a production input. A positive steady-state growth of per capita output cannot be sustained if the population growth rate or the output elasticity of land is sufficiently high. The study implements a panel data approach and shows that land may have an output elasticity as high as 1/3, suggesting that the natural environment indeed poses an important constraint on China's economic growth. In this study of the Chinese provinces, the panel data approach has implied much higher rates of conditional convergence in per capita output, compared with cross-section estimations.     

装备制造业全要素生产率动态测度

运用三阶段DEA模型,对1999～2007年我国各省装备制造业全要素生产率进行实证分析表明,各省的技术效率显著地受到环境变量和随机因素的影响,其中纯技术效率并不低下,且区域间差异较小,但规模效率低成为制约技术效率提升的关键因素。技术效率存在条件收敛,东部和中部收敛,而西部发散。进一步根据Malmquist指数分析还发现全要素生产率保持了11.8%的年均增长速度。     

Change and continuity in Japanese compensation practices: the case of occupational pensions since the early 2000s

This article analyses changes in the provision of Japanese occupational pensions since the early 2000s. It shows how Japanese companies have followed strategies of cost and risk reduction by creating multi-layered benefit systems that offer a combination of defined benefit (DB) and defined contribution (DC) plans whose benefits are becoming increasingly performance-oriented. Analysing the reasons behind the resilience of DB schemes in Japan, the article concludes that enterprise union behaviour has had less influence than regulatory issues and continued corporate commitment to long-standing employment practices for regular workers. These findings highlight the embeddedness of Japanese employment practices in their institutional context.     

Intermediate goods trade and international wage convergence in Central Europe

The recent literature on international outsourcing points out that cross-border fragmentation of production processes may foster the convergence of international factor prices. This paper makes a first attempt to analyze this hypothesis empirically using a small panel of NACE 2-digit wage data of three Central and Eastern European economies.     

Slow convergence of the number of near-maxima for Burr XII distributions

A near-maximum is an observation which falls within a distance a of the maximum observation in an independent and identically distributed sample of size n. Subject to some conditions on the tail thickness of the population distribution, the number K _n (a) of near-maxima is known to converge in probability to one or infinity, or in distribution to a shifted geometric law. In this paper we show that for all Burr XII distributions K _n (a) converges almost surely to unity, but this convergence property may not become clear under certain cases even for very large n. We explore the reason of such slow convergence by studying a distributional continuity between Burr XII and Weibull distributions. We have also given a theoretical explanation of slow convergence of K _n (a) for the Burr XII distributions by showing that the rate of convergence in terms of P{K _n (a) > 1} tending to zero changes very little with the sample size n. Illustrations of the limiting behaviour K _n (a) for the Burr XII and the Weibull distributions are given by simulations and real data. The study also raises an important issue that although the Burr XII provides overall better fit to a given data set than the Weibull distribution, cautions should be taken for the extrapolation of the upper tail behaviour in the case of slow convergence.
