辽宁省冰雪旅游发展存在的问题及对策探究

冰雪旅游已经在世界范围成为一种广为接受的主题休闲度假旅游产业。在我国,起步稍晚的冰雪旅游正在以惊人的发展速度崛起壮大,并且呈现出广阔的发展前景。辽宁省作为国内知名的冰雪旅游大省,目前仍存在着冰雪旅游产业整体滞后、市场监管不到位、专业人才缺口较大等具体问题。因此,辽宁省应进一步深挖冰雪旅游文化内涵,弥补专业人才短板,完善配套服务,整体提升冰雪旅游产业管理和服务品质,推动冰雪旅游健康蓬勃发展。     

INTERNATIONAL RESERVE MANAGEMENT: A DRIFT‐SWITCHING REFLECTED JUMP‐DIFFUSION MODEL

We study the cost of shocks, that is, jump risk, with respect to reserve management when the reserve process is formulated as a drift‐switching jump diffusion with a reflecting barrier at 0. Inspired by the Brownian drift switching model, our model results in a more realistic dynamic behavior of international reserves than the buffer stock model. The new model can capture both the jump behavior in reserve dynamics and the leptokurtic feature of the increment distribution which has a higher peak and two asymmetric heavier tails than the normal distribution. Through the selection of an initial distribution that reflects certain steady state behaviors, the reserve process becomes a regenerative process. This selection enables us to derive a closed‐form expression for the total expected discounted cost of managing reserves, thus helping us to numerically find management strategies that minimize costs. The numerical results show that shocks at the reserve level have a significant effect on reserve management strategies and that model misspecification can result in nonnegligible additional costs.

An exceptional development pattern

This paper investigates India's exceptional development pattern, specifically the major importance of information technology services (ITS), and compares it with China's development pattern. Both countries want to develop capabilities for carrying out the innovation of technologies that compete at the state-of-the-art in the world market. The paper posits that technological/economic success in the contemporary world market requires the ability to innovate complex technologies and complex technology-related services. The share of trade represented by complex technologies is compared with the “high-tech” share. The trading patterns of the two countries are compared using United Nations data. Two case studies of Indian ITS companies are then compared with two case studies of Chinese manufacturing companies. Historical and cultural differences appear to explain some of the differences in the development patterns of the companies located in the two countries.

中石化上游领域竞争力和抗风险能力的定量分析

在分析石油公司上游领域竞争力影响因素的基础上，提出了定量评价上游 领域竞争力和抗油价风险能力的定量评价方法，按上游综合竞争力指标将世界石油公司分为三类，第一类公司的指标值均在90以上，第二类公司在55－70，第三类公司在25－35。分析表明中石化集团上游领域竞争力较低，承受体油价的时间很短，但是，中石化集团公司上游竞争力和抗风险能力有很大的改善余地，并提出提高竞争力和抗风险能力的措施和建议。
