为巩固集体林权制度改革成果,完善涉林公益事业建设,江西省开展了涉林公益事业"一事一议"财政以奖代补试点工作,解决了林改后部分地区急需的林业公益事业建设问题。但试点的过程中也出现了发动执行不到位、制度成本过高等问题。在实地调研的基础上,对该政策的实施情况及出现的问题进行了分析,并提出了政策建议。 相似文献

It has often been claimed that a relative expansion of the service sector has a deleterious effect on economic growth. This paper uses cross-section country-level data from three decades –1960s, 1970s and 1980s – to see whether in fact this negative relation is reflected in the data. It is found that the effect is negative or positive depending on how the role of the service sector is measured, but there is a strong case that effect is in fact usually negative. 相似文献

We study socio-ecological models for a fishing ground open to tourists. On Jeju Island, Korea, women traditional divers called “Haenyeo” harvest resources in a common fishing ground. To investigate the impact of introducing tourists on the benefit to the fishing association and the resource level, we examine two models that differ in the way the number of tourists is controlled. In the first model, the fishing association charges an entrance fee to tourists and the level of the fee is chosen to regulate tourist number. In the second, only a part of the fishing ground is made open to tourists, and the fraction of the ground open is chosen to control the tourist number. In both models, the fishing association seeks to maximize its total benefit. Analysis shows that the way the number of tourists increases with the availability of resources strongly influences the distribution of benefits among the fishing ground stakeholders. Finally, we discuss policy implications of our results and how local government can reduce the risk of introducing tourism. 相似文献

For a balanced two-way mixed model, the maximum likelihood (ML) and restricted ML (REML) estimators of the variance components were obtained and compared under the non-negativity requirements of the variance components by L ee and K apadia (1984). In this note, for a mixed (random blocks) incomplete block model, explicit forms for the REML estimators of variance components are obtained. They are always non-negative and have smaller mean squared error (MSE) than the analysis of variance (AOV) estimators. The asymptotic sampling variances of the maximum likelihood (ML) estimators and the REML estimators are compared and the balanced incomplete block design (BIBD) is considered as a special case. The ML estimators are shown to have smaller asymptotic variances than the REML estimators, but a numerical result in the randomized complete block design (RCBD) demonstrated that the performances of the REML and ML estimators are not much different in the MSE sense. 相似文献

Performance lies arise both from individual and from situational causes, but in this article, the attention is on situational causes. These are generally triggered by loyalty to the coalition, which is expressed through the continued use of performance lies. Because performance lies help create a boundary around the coalition that insulates its activities from top management, performance lies enable members of the coalition to exercise a greater degree of internal control. Naturally, such lies are dysfunctional, resulting in the avoidance of difficult issues and problems and compromising the organization's ability to adapt to a changing environment based on accurate information. 相似文献

Summary Pseudo Bayesian estimators for the variance components based on Jeffrey’s Rule are derived for the mixed balanced incomplete
block design and are compared with the usual analysis of variance estimators in terms of mean squared error (MSE) efficiency.
Numerical results show that Pseudo-Bayesian estimators are more efficient in numerical results. 相似文献

改善我国股市生态的理论思考 总被引:2,自引:0,他引:2
如果从理论源头上追溯的话,传统发展观是构成我国股市生态系统脆弱的根源.股市"物理环境"即制度安排存在的巨大缺陷,股市生态系统中"生产者"生产能力低下,"生产者"与"消费者"角色错位,股市生态系统中不同"消费者"之间数量关系的失衡,股市生态系统中"分解者"的缺失,造成了我国股市生态系统的不稳定.再造健康的股市生态,我们就必须正本清源,突破传统发展观的樊篱,用科学发展观的观点认识和解决股市中的各种问题和矛盾. 相似文献
