We show, within a single industry, the possibility that R&D‐investment is non‐monotonically related to competitive toughness: increasing when competition is soft and decreasing when competition is tough. This possibility results from the combination of a Schumpeterian markup squeezing effect discouraging innovation, and a concentration effect spurring innovators. It is obtained in a sectoral model where the number of innovators is random and where non‐successful investors may remain productive. The result is extended to a multisectoral stochastic endogenous growth model with overlapping generations of consumers and firms, the number of which is endogenously determined in the capital market. 相似文献

辛亥革命值得纪念和追忆,这一段历史注定要在中国政治制度建设和政治现代化建设史上留下许多有价值的经验和教训,认真、客观总结和评价这一在中国民主进程中有着特别重要意义的历史阶段,对于我们建设有中国特色的民主政治是大有帮助的。辛亥革命后对国家政体的选择以《中华民国临时约法》为标志,共和代议政体正式确立。尽管共和代议政体运行并不理想,但建立了一个各种政治势力角力的平台,这是一个历史性的进步。这一段历史给我们以深刻启示:一是政治统治要具备政治合法性形式要件;二是政治改革进程中要创造和培育有利于推行宪政的社会环境,民众是社会进步的积极力量;三是宪政文化宣传和普及是一个长期的历史过程。 相似文献

This paper investigates the effects on production, consumption, and welfare that result from a temporary exchange-rate-based
(ERB) stabilization plan. The analysis is based on a dynamic optimizing model of a small open economy where real money is
assumed to be a factor that is used in the production of goods. The assumption of money serving a productive role makes the
model capable of generating a boom-bust cycle in output, as is often experienced during ERB stabilization plans. It is shown
that if the stabilization plan is expected not to be too short and/or the costs associated with the breakdown of the plan
are not too high, a temporary decrease in the rate of exchange rate devaluation will increase economic welfare. It is also
found that if some of the increase in output in the initial phase of the stabilization plan is saved for periods after the
plan has broken down, there is a greater chance that the ERB plan will increase economic welfare. On the other hand, if the
plan is not sufficiently credible at the outset, or there is not enough intertemporal transference of output, the stabilization
plan is likely to be harmful to economic welfare.

联络中心排班需要准确预测到达任务量的各种类型。联络中心任务量数据庞大复杂,针对多类型任务的预测方法进行了研究,实现了对联络中心大量任务数据进行准确预测类型任务的目的。首先分析了任务量数据特点,确定了工作日和休息日对任务类型的影响。工作日使用PSO优化LIBSVM模型的参数,作为弱分类器用自适应增强算法迭代训练,提出用加权投票方法融合弱分类器的思想;休息日直接使用PSO-SVM模型预测。实验结果表明,该方法的分类准确率相对于传统方法准确率有很大提高。这对联络中心的人员排班管理具有重要的作用,对其他的服务行业的任务预测分类也有重要的参考价值。 相似文献

Labor contracts are repeated, and the current negotiation apparently affects negotiations on the next contract. There is evidence that the likelihood of a strike is influenced by what happened before the previous contract was signed. To analyze whether private information might explain this, a model of negotiations between a buyer and a seller is developed where the “pie” in each contract follows a Markov chain, with transitions observed privately by the buyer. Each negotiation is a sequence of offers by the seller; the buyer can only accept or reject each offer, and a contract is signed when the buyer accepts. 相似文献

我国对外直接投资与技术进步关系的实证研究 总被引:9,自引:0,他引:9
本文通过对我国对外直接投资和TFP时间序列数据分别进行平稳性检验,发现二者的一阶差分序列均是平稳的,所以它们之间有长期的稳定关系;然后进行因果关系检验,得到TFP是我国对外直接投资的原因;最后进行回归分析并得出结论:我国国内各部门的技术进步是对外直接投资增加的主要原因之一,并且对我国对外直接投资增长具有巨大的推动作用。 相似文献

在满洲里国家重点开发开放试验区建设中,开发与开放是一对不可分割的矛盾体。开放是试验区的一面旗帜,引领着试验区各项改革事业的发展;开放还是一种眼界,预示着必须以长远的战略眼光去谋划试验区的开发建设;开放又是试验区的尺度,规范着满洲里试验区宽度和广度。开放就是满洲里试验区建设的灵魂,是国家设立和建设满洲里试验区的出发点和落脚点,是关系到满洲里试验区能否最终建成的生命线。 相似文献

We consider a situation in which a raider attempts to seize corporate control from a leading large shareholder who chooses between undertaking intervention in the management of the firm and selling its stake to increase its expected payoff. A takeover is more likely to succeed the lower is the ownership concentration of the target firm. However, the higher are the costs of a takeover, the greater must the ownership concentration be for the raider to attempt a takeover. If there is a takeover, the value of the target firm is lower the greater is its ownership concentration. 相似文献
