论国有企业经营者激励机制设计的客体假设

本文从激励机制设计的客体假设出发，指出当前我国国有企业经营者激励机制问题的根源在于对经营者这一激励客体的错误假设。由于沿用计划经济体制下的“政治人”和“劳动者”假设，目前的经营者激励机制不符合转轨期乃至市场经济体制下激励客体的实际，从而出现激励机制失效甚至适得其反。本文探讨了两种体制下我国国有企业经营者激励机制设计的不同经营者假设，以及在“自利人”和“企业家”的经营假设下国有企业经营者激励机制设计思路。

Innovation and business survival: A long-term approach

This paper explores the influence of innovation on the probability of survival of two hundred top British firms founded throughout the nineteenth and twentieth centuries. To this end, we have collected the firms’ significant innovations and classified them by Schumpeterian types, patented and non-patented and domestic and imported. The number of patents registered by the firms throughout their lifetime ?a rough measure of their incremental innovation activity– has also been recorded. In addition, twelve control variables ?five characteristics of the firms and seven of their business leaders– have been included. Both log-normal and gamma duration models have been used in the analysis. They have been estimated, firstly for the whole set of firms and, secondly, for the manufacturing and the service firms separately to control for industry differences. The results of the log-normal and gamma estimations are highly coincident, with some nuances. The significant innovations ?particularly new processes, non-patented and domestic ones– have been found to positively influence the probability of business survival. The number of patent applications seems to increase the survival probability of the manufacturing firms, but not of the service ones. Among the control variables, the firm’s size, its international dimension, and the age of the business leader at entry seem to be the most influential ones on business survival, although there are some differences between manufacturing and services. The main results are robust to the division of the sample by entry period.     

世界女子平衡木技术发展的新趋向——第41届世界体操锦标赛分析

依据第41届世界体操锦标赛实况录像及相关资料,采用文献资料法、录像观察法及数理统计法,系统分析了当今世界女子平衡木技术发展的新趋向。发现：以舞蹈和技巧两类高难度的单个动作结合具有高连接价值的技巧连接、混合连接（或再结合转体二连接）及仅具有＂编排价值＂的A＋A舞蹈连接和低难度＂单转体＂,组成由最高难度的5个技巧和3个舞蹈动作构成的具有高D分价值的成套8个难度动作,是当今世界女子平衡木技术发展的新趋向。而适合新规则变化特点的＂技/平衡（D＋A）＂连接及＂转体/转体（C＋A或相反）＂的连接,还将被更多优秀选手用于提高成套动作的连接价值和增加成套动作的完成类型。     

世界女子平衡木技术发展的新趋势及中国的优势与不足

采用文献资料法、录像观察统计与比较等方法,系统分析了当今世界女子平衡木技术发展的新趋向及中国的优势与不足.以舞蹈和技巧两类高难度的单动作结合具有高连接价值的技巧连接、混合连接（或再结合转体二连接）及仅具有编排价值的低难度舞蹈直接串和单转体,组成由最高难度的5个技巧和3个舞蹈动作构成的具有高D分价值的成套8个动作,是女子平衡木技术发展的新趋向;中、外选手成套D分难度价值使用的技巧和舞蹈动作的比例及采用的完成形式相当,成套D分价值以中国最高,并对前空翻类、直体后空翻及羊跳等动作的个性化技术连接,占有领先优势;而减少连接停顿和失误、强化动作连接价值质量及提高成套动作完成的熟练稳定性等,还是中国女子平衡木亟待解决的首要问题.     

International patent disputes: Evidence from oppositions at the European Patent Office

The impact of the geographical origin of patents on the probability of an opposition being filed and a patent being revoked has been examined in this paper, after accounting for patent value indicators and industry specificities. The study is based on a dataset of approximately 450,000 EPO granted patents and 24,000 patent opposition cases in the years 2000–2008. We find that patents with a first priority in the US are less likely to be challenged, although they are relatively more likely to be revoked than patents with a priority in a member country of the European Patent Convention. Patents from Japan have less probability of being opposed and are less likely to be revoked than the other countries. A disaggregation of the European countries has revealed that patents with a German priority have a higher or similar likelihood of being opposed than patents from the other countries, with the exceptions of The Netherlands and Denmark.
