俱乐部旅游:实施、意义与前景

本文根据实地调研，讨论国内新近出现的一种新的旅游方式——俱乐部旅游。文章首先分析这种旅游方式成功实施的三要素，即相关主体、旅游线路设计、物质准备及费用；其次，从旅游者、当地社区、旅游组织者以及旅游目的地生态环境和遗产保护等角度，对俱乐部旅游进行收益分析，并同时与其他旅游方式进行效益比较；第三，通过讨论俱乐部旅游与“大众旅游”、“自助旅游”、“另类旅游”以及“活动旅游”等旅游概念的关系，对其进行学术定位；最后，从俱乐部旅游的易行性、潜在的参加者群体、与户外健身运动的关联性、以及中国户外运动资源等4个方面，指出俱乐部旅游在中国的发展前景。     

Distinguishing Between Rationales for Short‐Horizon Predictability of Stock Returns

In this paper, we shed light on short‐horizon return reversals. We show theoretically that a risk‐based rationale for reversals implies a relation between returns and past order flow, whereas a reversion in beliefs of biased agents does not do so. The empirical results indicate that returns are more strongly related to own‐return lags than to lagged order imbalances. Thus, the evidence suggests that monthly reversals are not completely captured by inventory effects and may be driven, in part, by belief reversion. We do find that returns are cross‐sectionally related to lagged imbalance innovations at horizons longer than a month.     

旅游现象矛盾论

旅游现象是一个矛盾复合体，其中旅游者活动的基本矛盾与旅游产业活动的基本矛盾是旅游现象矛盾体的核心部分。在旅游产业中，旅行社是销售分公司，生产最终产品；旅游住宿等行业／企业是“制造”分公司，生产中间产品。本文运用系统思考方法，架构了旅游现象的矛盾体模型、旅游者活动的基本矛盾及其运行模型、旅游产业活动的基本矛盾及其运行模型。     

质量成本收益分析

质量活动与财务业绩之间似乎不相关现象越来越明显。关于质量成本的讨论也慢慢淡出人们的视线。在管理会计行业中ROQ(ReturnonQuality)这一思想在美国却越来越受到关注。寻找质量活动与财务业绩之间正在失去的相关性成为目前一个重要的课题。本文在明确ROQ特征的基础上,从ROQ的角度,探讨质量活动与财务业绩的关系。

Takeover activity in Australia: endogenous and exogenous influences

The present paper analyses the population of takeover bids for listed Australian companies using quarterly data over a 25-year period to re-examine the predictability of takeover activity and to determine if there is a flow on impact on macroeconomic variables. We examine whether takeover activity: (i) is endogenous; that is, determined by own activity; (ii) is jointly determined by macroeconomic and capital market variables; and (iii) has an exogenous spillover impact across the economy. We find that stock prices and takeover activity share a long-term common trend, the relative success of takeover bids is independent of sharemarket activity, and conclude that aggregate takeover activity is driven by fundamental economic factors rather than by speculative activity.

基于知识增加值的业务流程质量评价

首先,引入了知识增加值概念,介绍了运用知识增加值评价业务流程质量的三种方法及其步骤。其次,为了更深刻地理解知识增加值,通过一个案例来说明知识增加值的核算步骤,并且与传统的作业成本分析法进行比较。最后,指出了知识增加值在实际应用过程中可能碰到的问题。但是,可以确信,随着知识经济的发展,知识增加值这种新的方法是会得到更为广泛的应用。     

Patents,R&;D and lag effects: evidence from flexible methods for count panel data on manufacturing firms

This paper investigates the relationship between patents and research and development expenditures using new longitudinal patent data at the firm level for the U.S. manufacturing sector from 1982 to 1992. The paper also develops a new class of count panel data models based on series expansion of the distribution of individual effects. Estimation results from various distributed lag and dynamic multiplicative panel count data models show that the contemporaneous relationship between patenting and R&D expenditures continues to be strong, accounting for over 60% of the total R&D elasticity. The lag effects are higher than have previously been found for the 1970s data. We would like to thank Chris Bollinger, Bronwyn Hall and Paula Stephan for useful comments on the previous version of the paper. Earlier versions were presented at the 11th International Conference on Panel Data, Texas A&M University, the Midwest Econometrics Group Meeting, and the Annual Conference of the Southern Economic Association.     

基于价值链的生态产业链构建及对策研究

生态产业是本世纪产业发展的一种新型模式。构建生态产业链,发展生态产业是实施循环经济,促进全球经济模式由线性经济向生态型经济转变的有效途径。本文以产业生态学的思想为基础,针对目前生态产业链在实践中所面临的问题,运用价值链的理论框架分析生态产业链,将生态价值融入经济价值中,提出了构建生态产业链的对策建议,从而为我国的产业生态化建设和循环经济发展提供理论参考。
