基于合作研发组织下的隐性契约稳定性比较

本文研究企业与科研机构组成的合作研发组织下的隐性契约。双方虽然事前有参与合作的动力,但是由于存在组织下的合作研发外溢效应,这种外溢既有合作双方间的外溢风险,又有协议实施和背弃的外溢风险。本文从厂商立场出发,通过分析合作中采用何种隐性契约控制和限制外溢风险发现,当溢出率较小时采用长期雇佣契约更稳定,而溢出率较大时采用技术支持契约更稳定。     

基于MRCI的中国能源消费变动及驱动因素分析

如何减缓能源消费的过快增长是应对能源安全和气候变化的重要课题。通过对投入产出分析原理和无残差的完全结构分解法（MRCI）量化分析发现,产出规模效应和生产结构效应对中国能源消费增长起到主导作用,是主要驱动因素,而中国能源强度效应能有效抑制中国能源消费的增长;人口规模效应和人均生活能耗效应对中国能源消费增长的影响相对较小,但也有一定的促进作用。因此,依靠技术创新、提高能源使用效率,控制人口增长、引导居民向低能耗方向发展有利于减少中国能源消费水平。     

产业结构高级化与经济增长关系实证研究——基于全国、广东省及广州市数据的对比分析

本文构造了一种能有效度量产业结构高级化的指标,并运用它对全国、广东省及广州市1978-2009年产业结构高级化与经济增长的关系进行了分析。结果发现,研究期间三个层次的产业结构高级化水平都得到了极大的提高,也表现出了相同的趋势、特征与路径。从全国到东部发达省份再到东部中心城市,经济增长对产业结构高级化都有推动作用,而产业升级对经济增长的促进作用则只出现在中心城市这一层。     

Risk‐Off Episodes and Swiss Franc Appreciation: The Role of Capital Flows

During episodes of increased global risk aversion, or risk‐off episodes, safe haven currencies such as the Swiss franc tend to appreciate. The immediate impact of a risk‐off shock is an increase in net private inflows to Switzerland, mostly driven by a reduction in Swiss residents’ net purchases of foreign debt securities and reduced foreign exposure by Swiss banks. Given that the bulk of capital movements related to risk‐off episodes is driven by decisions of Swiss residents, capital flow management policies that discriminate based on the residency of the investor (capital controls) are not likely to be effective at reducing the impact of risk‐off episodes. However, prudential policies that limit leveraging or foreign exposure by Swiss banks may diminish the volatility of capital flows during risk‐off episodes.     

要素结构与技术进步方向——来自中国城市“撤县设区”的证据

本文基于1997—2010年267个地级及以上城市市辖区面板数据,运用标准化供给面系统方法测算了市级层面的技术进步方向,并借助“撤县设区”这一自然实验,利用工具变量法实证检验了要素结构变动对技术进步方向的影响,研究发现：（1)“撤县设区”使得资本—劳动比上升,进而导致技术进步方向偏向于资本,符合偏向型技术进步的“弱诱导偏向型假说”;（2)“撤县设区”对资本偏向型技术进步的影响是有条件的,主要限于资本—劳动替代弹性大于1即资本—劳动呈替代关系的地区;（3)相比于中西部地区,东部地区资本要素更为丰富,因而“撤县设区”显著提高了东部地区的资本—劳动比,使其技术进步方向偏向资本。     

基于蚁群聚类算法的绿色内陆港宏观布局研究

为解决绿色理念指导下的内陆港宏观布局问题,考虑了备选城市的环境友好性对内陆港发展空间持续性的影响,首先分析影响内陆港宏观布局的因素,之后选取具有较强鲁棒性、采用正反馈原理的蚁群聚类方法,从经济发展水平、多式联运能力、政策环境、发展空间持续性等角度,构建绿色内陆港布局模型.最后以天津港为对象的实例分析表明,蚁群聚类模型对于解决环境友好型内陆港布局问题是有效的,结果基本符合实际情况.该研究为构建绿色内陆运输网络、实现绿色物流提供了科学方法.     

The impacts of SOX and SEC investigation on the corporate governance of option backdating firms

This study investigates the combined impact of the Sarbanes-Oxley Act of 2002 (SOX) and the subsequent related Securities and Exchange Commission's (SEC) initiatives on the corporate governance characteristics of firms that had historically backdated stock options. Our results show that backdating firms had both weaker board-level and committee-level corporate governance characteristics than control firms in the pre-SOX period. In contrast, backdating firms dress up their board-level governance to meet regulatory requirements but still feature weaker committee-level corporate governance in the post-SOX era.     

农村人力资本投资结构与内生经济增长

本文从理论上构建了农村人力资本投资结构(包括私人和公共)对农村经济增长影响的模型,运用我国四大经济地区面板数据分析了农村私人和公共教育投资与健康投资对人力资本增量的促进作用,以及人力资本增量对农村经济增长的内在影响并加以检验.结果主要表明:农村人力资本投资结构对人力资本增量,人力资本增量对农村经济增长都具有一定的正向作用;农村私人和公共人力资本投资相对强调了教育投资而轻视了健康投资;私人人力资本投资产出效率高于公共人力资本投资产出效率;四大地区农村人力资本投资额与结构都存在较为明显的差距.     

The development of the Personality Audit: a psychodynamic multiple feedback assessment instrument

The Personality Audit (PA) was developed to meet a need for a relatively simple multiple feedback instrument that could clarify the various motivational needs of executives. Using a psychodynamic approach to leadership, the PA allows the test-taker to assess him- or herself in seven personality dimensions important in human behaviour and to identify personal ‘blind spots’. The resulting insights can be used to formulate appropriate leadership development goals.

The objective of this paper is to describe the design and psychometric properties of the PA. This instrument, in contrast with other tools that can be used to clarify the inner theatre of individuals, is designed not only to report information given by the test-taker but also to reflect the perceptions of observers representing both the test-taker's public and private spheres. This paper describes in detail the conceptual foundations of the questionnaire, the psychometric methods used to confirm its validity and reliability, and possible directions for future research.     

认知OFDM系统旁瓣抑制新方法

针对认知正交频分复用（OFDM）系统带外辐射（OBR）严重问题,在研究基于功率谱密度的主动干扰消除算法（PSD-AIC）模型的基础上,提出了动态PSD-AIC的方法,通过对每一子载波位置OBR的计算,比较选择出OBR取值最小处,作为对消子载波的最优位置,显著改善了系统对OBR的抑制性能（增大约10dB）。对比分析了算法的计算开销,研究了设计参数对OBR的影响,提出了实际应用时的参数选择基准。仿真结果和理论分析表明,动态PSD-AIC方法可以显著减小带外干扰。与PSD-AIC方法相比,旁瓣抑制深度可增加约10dB;与传统AIC方法相比,只需相似计算量,干扰抑制性能便可明显增加。
