旅游业已经成为现代经济增长一个新的亮点,特别是生态文化旅游的增长速度更是惊人,而其发展的价值平衡是生态学和经济学必须面对的一个难题。本文依据意大利经济学家帕累托的不均匀分布定律,运用埃奇渥斯盒状分析图,在某一选定的生态资源环境的承载量既定的基础上,从生态文化旅游的价值交换的角度考虑,并且从定性研究转向定量研究,分析研究生态文化旅游的价值帕累托最优曲线,用以筛选生态文化旅游的工程项目。  相似文献

Through the development and extension of theories and scholars’ subsequent empirical analyses of significant, theoretically grounded research questions, the knowledge about corporate entrepreneurship (CE) and its successful use continues to advance. Moreover, the literature suggests important relationships between the corporate environment, managers’ entrepreneurial behavior and successful implementation of corporate entrepreneurship actions. In an attempt to test some of those relationships, we describe an empirical study of 523 managers that examines the relationships among the antecedents to managers’ entrepreneurial behavior, a decision to implement entrepreneurial actions, and resulting job satisfaction and reinforcement practices.  相似文献

We examine the performance of a metric entropy statistic as a robust test for time-reversibility (TR), symmetry, and serial dependence. It also serves as a measure of goodness-of-fit. The statistic provides a consistent and unified basis in model search, and is a powerful diagnostic measure with surprising ability to pinpoint areas of model failure. We provide empirical evidence comparing the performance of the proposed procedure with some of the modern competitors in nonlinear time-series analysis, such as robust implementations of the BDS and characteristic function-based tests of TR, along with correlation-based competitors such as the Ljung–Box Q-statistic. Unlike our procedure, each of its competitors is motivated for a different, specific, context and hypothesis. Our evidence is based on Monte Carlo simulations along with an application to several stock indices for the US equity market.  相似文献

Business school deans’ feelings about the importance of various teaching research and service activities in the roles played by holders of endowed chairs in Entrepreneurship were contrasted with the views of chair holders themselves, based on their experiences. Differences were highlighted and discussed. Results suggest that the chair holder role is negotiated between multiple constituencies, with deans’ influence being strong but limited. Implications for individuals aspiring to hold chairs are discussed.  相似文献

This paper presents a new approximation to the exact sampling distribution of the instrumental variables estimator in simultaneous equations models. It differs from many of the approximations currently available, Edgeworth expansions for example, in that it is specifically designed to work well when the concentration parameter is small. The approximation is remarkable in that simultaneously: (i) it has an extremely simple final form; (ii) in situations for which it is designed it is typically much more accurate than is the large sample normal approximation; and (iii) it is able to capture most of those stylized facts that characterize lack of identification and weak instrument scenarios. The development leading to the approximation is also novel in that it introduces techniques of some independent interest not seen in this literature hitherto.  相似文献

This paper focuses on the fundamental changes in the management of state enterprises that are taking place in China. Specifically, we discuss the expansion of enterprise autonomy and changes in the managerial decision-making structure. The genesis of the reform programme is traced back to inefficiencies caused by the over-centralized state planning system which reduced enterprise management to little more than an administrative function dominated by the Party secretary. As a consequence, managerial and technical cadres became demoralized and the growth of staff functions such as accounting, marketing and personnel management was stunted. From a series of experiments launched in 1978 has grown the realization that tinkering around with the state planning apparatus is insufficient to stimulate entrepreneurship and vigorous industrial expansion. Accordingly, reform has been launched on a broad front both within the state apparatus, in an endeavour to roll back external constraints on enterprise, and within the enterprise itself, by seeking to provide powerful incentives both to managerial cadres and workers through a system stressing individual responsibility and rewards commensurate with results. A number of severe constraints on the reform programme are analysed, in particular, the changing balance of power within the enterprise between the factory director, the Party secretary, the workers’congress and the trade union. Contradictions exist within the new structure of decision-making but, given a period of political stability and sustained economic growth, there should be sufficient surplus to mollify discontent and stifle those who refuse to give up their belief in the virtues of having‘politics in command’of the industrial enterprise.  相似文献

A curtailed test for the shape parameter of the Weibull distribution   总被引:1,自引:0,他引:1  
Summary A procedure is proposed in this paper for testing the shape parameter, of the Weibull distribution. The test statistic which is based on the extremal quotient, possesses a monotone property which makes it possible for rejection earlier than the last planned observation of the null hypothesis,H 0: =0 when the alternative hypothesis isH a: <0 and early acceptance ofH 0 whenH a: >0. The test being scale-free, does not require the scale parameter to be known.  相似文献
