城市发展战略是城市管理导引的主导性环节。城市产业发展战略是城市发展战略的核心内容。在当前形势下,我国城市产业发展战略面临以下三大课题:面对“入世”对我国提出的挑战和机遇,城市产业应提出“应对战略”;面对知识经济的到来和我国与发达国家存在的差距,城市产业应提出“追赶战略”;面对我国城市产业发展自身长期存在的不协调和不适应问题,城市产业应提出“调整战略”。 相似文献

1.风险投资的实质风险投资(venturecapital),在国外又称创业投资,是指将资金投入到快速成长的、具有高度不确定性的未上市中小企业,以期获得高收益的投资行为。风险投资家以专业知识主动参与经营,使被投资企业能够健全经营、迅速成长,风险投资家可在被投资企业成功后,将所持有股票卖出,收回资金及其高额利润,再投资于另一新创企业,复始进行中长期投资并参与经营。风险投资家以获取股息、红利及资本利得为目的,其最大特征是甘冒较大风险以获取巨额资本利得。与其他投资相比,风险投资的特殊性在于其投资收益是通过转让风险企业的股权而实现增… 相似文献

Several theoretical approaches have been put forth to predict and explain the effects of teleconferencing technologies. One approach is to examine the functions of nonverbal signals and to make predictions based on the fact that different teleconferencing technologies allow nonverbal communication to different extents. One of the functions of nonverbal signals is to allow the listener to provide feedback to the speaker in a communication. Prior research has shown that such feedback enhances listener comprehension. In this study, it was hypothesized that different teleconferencing technologies would allow different levels of feedback based on their ability to accommodate nonverbal signals, and this in turn would affect comprehension. An experimental study was conducted to compare comprehension, feedback, and satisfaction in telephone and computer conferencing. The study confirmed that comprehension and speaker satisfaction are related to feedback, but failed to show a relationship between listener satisfaction and feedback. No difference in comprehension, listener, or speaker satisfaction was observed across teleconferencing technologies. Role-related differences were observed between the speaker and the listener. It is suggested that the effects of teleconferencing technologies can be mapped systematically by examining each of the functions of nonverbal signals, one at a time. 相似文献

In this note, we make some remarks on the construction of sequences of independent identically distributed random variables and of Markov chains concretely on a probability space (Ω,A,P). We also show that there are non non-trivial martingales of exponential type. 相似文献

This study investigates the relative influences of professional values and selected demographic variables on the ethical perceptions of services marketing professionals. The relationship between ethical perceptions and ethical judgments of service marketers is also examined. The data were obtained from a mail survey of the American Marketing Association's professional members of service industries. The survey results indicate a positive relationship between a service professional's professional values and his/her perceptions of ethical problems. The results also suggest that ethical judgments of a service professional can be partially explained by his/her perceptions of ethical problems. Implications of the research findings were discussed.

In this paper, we consider the case of finite time dimension in the panel stationarity tests with structural breaks. By fixing T, the finite sample properties of the tests for both micro (T small and N large) and macro (both T and N large) panel data are generally greatly improved. More importantly, the derivation of the tests for finite T and , as opposed to joint asymptotic where N and simultaneously, avoids the imposition of the rate condition making the test valid for any (T, N) blend. Four models corresponding to the usual combination of breaks are considered. The asymptotic distributions of the test are derived under the null hypothesis and are shown to be normally distributed. Their moments for T fixed are derived analytically employing Ghazal’s corollary 1. The case with unknown breaks is also considered. The proposed tests have generally empirical sizes that are very close to the nominal size. The Monte Carlo simulations show that the power of the test statistics increases substantially with N and T. 相似文献

Increased tradability of services, made possible by the information and communications technology (ICT) revolution, has been at the heart of the internationalization of services. Although rapid growth of the services trade between parents of multinational enterprises (MNEs) and their overseas subsidiaries has contributed to the internationalization of services, empirical studies examining the determinants of intra‐MNE trade in services are few. This article, using the ownership, location, and internalization (OLI) framework, attempts to explain intra‐MNE trade in services. The results provide strong support for the OLI perspective, and posit a complementary relationship between manufacturing foreign direct investment and intra‐MNE services trade. The results also suggest the importance of subsidiaries' absorptive capacity and breadth of global connectedness for intra‐MNE trade. 相似文献

Family influences on economic performance are investigated. In particular, sibship sex composition is related to hourly wages using data from the National Longitudinal Survey of Youth 1979. The wages of men are increasing in the proportion of siblings who are brothers, but the wages of women are insensitive to sibling gender. Nonwage outcomes are generally unaffected. Contrasts by age structure and demographic group are also presented. The analysis addresses econometric challenges like the endogeneity of fertility and selection into the workforce. In addition, mechanisms such as labour market interactions, human capital investment and role model effects are documented. A questionnaire on job search indicates a same-gender bias in the use of brothers and sisters in obtaining employment. Developmental and psychological assessments suggest that brothers may be associated with worse childhood home environments and more traditional family attitudes among women. The findings are policy relevant and contribute to an understanding of gender differences and earnings inequality. 相似文献
