论市场所有权

本文作者首次在国内外提出了市场所有权理论，作者认为，过去我们对企业微观产权（包括有形产权和无形产权）研究较多，而忽视了对这些微观产权赖以存在的基础和实现条件－－市场产权的研究。实际上，市场本身也有一个产权界定及其制度安排问题，本文在界定产权概念的内涵，本质与功能的基础上，认为市场产权由狭义市场所有权，市场使用权（经营权），市场占有权和市场收益权等四个要素构成，认为市场产权具有五个方面的基本特征；市场所有权的稀缺性，市场所有权的准资本属性；市场所有权的排他性；市场经营权的可转让性；市场所有权收益的可计量性等，市场产权具有三种基本形式；市场国家所有制；市场区域共享制；市场全球共享制等，虽然市场市场产权天生具有国家排他性，归一国政府所有，但市场经营可以转让，各种贸易战的实质是争夺市场经营权，控制权和收益权，区域经济一体化和经济全球化是市场经营经营权的有限互换和交叉分享。     

论我国地方财政风险的个性特征

我国地方财政风险，不同于一般的财政风险。从整体考察，它具有分散性、非均衡性和传导性；从结构考察，具有隐蔽性、发展性和内生性，同时它又受外部因素的影响很大。     

Characteristics of Earnings-Leading Versus Price-Leading Firms

This study attempts to identify firm characteristics that explain the disparity between the information content of accounting earnings and stock prices. Granger's causality concept was employed to classify sample firms into four groups: price-leading firms, feedback-system firms, earnings-leading firms, and no-causation firms. The feedback-system firms were either combined with the no-causation firms or eliminated entirely to form three sample groups. The entire sample firms then were divided into two classes. The first is for estimation, and the second is for prediction. Results indicate that firm size, capital structure, R-square of regressing prices at time t against earnings at time t – 1, R-square of regressing earnings at time t against prices at time t – 1, and percentage of shares held by institutions are the significant explaining variables. The application of the coefficient estimates to the hold-out sample indicates that 76.2% of the firms can be correctly classified into the corresponding groups. These results were consistent with those from canonical discrimination and other multivariate statistical methods.     

Mutual fund characteristics, managerial attributes, and fund performance

This study provides a comprehensive examination of recent mutual fund performance by analyzing a large set of both mutual funds and fund attributes in an effort to link performance to fund-specific characteristics. The results indicate that the hypothesized relationships between performance and the explanatory variables are generally upheld. After taking into consideration general market conditions and fund investment objective, the characteristic variables that relate to fund popularity, growth, cost, and management also explain performance. Finally, after controlling for survivorship and benchmark error as well as fund-specific factors, the results refute the performance persistence phenomenon.     

Logics,Leaders, Lab Coats: A Multi‐Level Study on How Institutional Logics are Linked to Entrepreneurial Intentions in Academia

Situated in the context of academia, this study integrates ideas from institutional theory, person‐environment fit theory and leadership research to conceptualize and examine the cross‐level link between the organizational‐level institutional logic of research commercialization and the entrepreneurial intentions of researchers. Multi‐level analyses based on a sample of 254 researchers working for 85 research group leaders in 49 German research institutes reveal that two distinct attributes of research group leaders – that is, their track records of entrepreneurial behaviour and their entrepreneurial intentions – play a significant role in transmitting the organizational‐level logic to the individual level. We also observe a complementary interaction between organizational‐level commercialization logic and the entrepreneurial track records of leaders. We discuss how these findings advance our understanding of science commercialization through academic entrepreneurship and how they inform institutional theory and theory development in other domains of entrepreneurship research.     

Properties of Census Dual System Population Size Estimators

We study parametric and non‐parametric approaches for assessing the accuracy and coverage of a population census based on dual system surveys. The two parametric approaches being considered are post‐stratification and logistic regression, which have been or will be implemented for the US Census dual system surveys. We show that the parametric model‐based approaches are generally biased unless the model is correctly specified. We then study a local post‐stratification approach based on a non‐parametric kernel estimate of the Census enumeration functions. We illustrate that the non‐parametric approach avoids the risk of model mis‐specification and is consistent under relatively weak conditions. The performances of these estimators are evaluated numerically via simulation studies and an empirical analysis based on the 2000 US Census post‐enumeration survey data.     

云南省老油房石灰岩大理石矿矿床特征及矿石工艺特征

在充分收集区域地质、野外调查和样品测试分析的基础上,系统地研究了云南省西畴县老油房石灰岩大理石矿的地质背景、成矿条件、矿床特征及矿石的工艺特征。结果表明该矿区矿体产状稳定,成层状产出;品种为灰色生物灰岩大理石,矿石体重适中;吸水率低,抗风化能力强;莫氏硬度较低,便于切割分离;耐磨率适中,便于打磨抛光;抗压、抗折、抗剪强度满足饰面石材工业技术指标要求;荒料率、板材率明显高于国家标准,适宜开采;可为大理石矿的勘查、开采、加工等方面工作提供参考。     

Determinants of Consumer Preferences for Honey in the Democratic Republic of Congo

Honey is one of the important non-timber forest products consumed in the Democratic Republic of Congo (DRC) and, as such, an important source of income for many households. However, poor knowledge of buyers’ preferences in the marketing of honey presents a major challenge to the profitability of the honey enterprises. The research presented in this article identifies key consumer characteristics that influence the preferences of honey consumers in the DRC. The primary data source used in this analysis is drawn from a survey of 214 consumers. Results show that consumers who are married and have reached at least the level of secondary education have a strong preference for local forest and savannah honey. Those between the ages of 30 and 50 do not prefer honey from beekeeping, but would rather have it imported. We conclude that segmentation of the honey market and increasing consumer awareness must go in tandem in order to develop a good marketing strategy.     

Individual stock sentiment beta and stock returns

Using the data in Chinese stock market, we measure the individual stock sentiment beta, which is defined as the sensitivity of individual stock returns to the individual stock sentiment changes. We demonstrate that stocks in the highest individual stock sentiment beta portfolio have significantly higher excess returns, CAPM alpha, Fama-French three-factor alpha and Fama-French five-factor alpha. Besides, we find that the high individual stock sentiment beta stocks are smaller, younger, more volatile stocks with higher price and higher market beta. After controlling for firm characteristic, the returns of High-Low individual stock sentiment beta portfolios are still significantly positive. Moreover, we show the effect of the individual stock sentiment beta on stock returns is positive and significant in different stock markets, in different sample periods, and in bull and bear market. Besides, the results of the Bayes-Stein individual stock sentiment beta are still stable.     

浅析新时期我国高校办学定位和战略管理

近一个时期,我国高等学校普遍开始重视办学定位和战略规划,这是好事,但重视不能仅仅停留在口头,更要落实在行动上。那么,不论是口头还是行动之前,都要做好充足的功课。笔者在高校工作多年,关于高校定位和战略规划借此发表自己的拙见,与读者分享,敬请批评指正。
