区域经济视角下国内支线航空发展困境的成因分析

区域经济是一种综合性经济发展的地理概念,反映区域性的资源开发和利用的现状及其问题,尤其是反映一定区域内各种经济资源的合理利用程度。从区域经济的角度来看,当前中国国内支线航空发展陷入困境的成因,很大程度上是在于我们对支线航空区域发展布局的科学性和社会总体经济效益重视程度不够,没有从各地区的实际情况出发进行支线机场的规划建设。     

关于中国台湾可持续发展指标体系的思考

目前国际上多个国家与地区建立了可持续发展指标体系,中国台湾地区在2003年已形成了较为完整的永续台湾评量系统.可持续发展战略作为中国大陆的基本国策,相关指标体系的研究近年来取得不少进展,但仍然缺乏明确的负责机构且未形成全国统一的可持续发展指标体系.因此,应尽快建立专门的可持续发展指标体系负责机构,注重可持续发展指标体系的实际操作性,并与国际可持续发展指标体系接轨.

Effect of supervisor–subordinate guanxi on supervisory decisions in China: an empirical investigation

As China is becoming an important market and there are a lot of foreign ventures operating there, different lines of research have been providing useful information for foreign ventures to manage effectively in China. In this paper, we discuss one of the critical factors leading to successful management of Chinese subordinates, i.e. building and maintaining good guanxi (i.e., interpersonal connection) with them. We conducted an empirical investigation to illustrate (1) the supervisor-subordinate guanxi concept is different and unique when compared to other similar concepts in the Western literature such as leader-member exchange (LMX) and commitment to supervisor; (2) the supervisor-subordinate guanxi will affect the Chinese supervisor's administrative decisions; (3) guanxi can be measured by concrete behaviour/activities. Data on 189 supervisor-subordinate dyads were collected in the People's Republic of China (PRC). Results indicated that supervisor-subordinate guanxi is a distinct concept from LMX and commitment to supervisor. It also has additional explanatory power over supervisory decisions on promotion and bonus allocation after controlling for performance. Implications for foreign ventures and expatriates are discussed.     

人口新常态约束下特大城市的规模调控与转型升级

不同国家、不同历史时期的特大城市人口规模变动极大,运用 Kernel 密度函数对中国城市人口规模分布的分析表明,当前以城区常住人口“500万以上”为特大城市的划分标准是合理的。从城市人口规模变动的动态历程来看,该变动主要受城市产业与经济发展的影响。对中国主要特大城市实有人口规模变动的分析表明,特大城市的人口规模调控应因时因地而动,不能搞一刀切,而且人口调控政策重点应该从数量控制转向结构优化。特大城市转型升级面临着农民工供给短缺、大学毕业生相对过剩、老年和少儿非劳动力人口持续增长等人口新常态约束。在这种人口增长新常态背景下,特大城市应坚持市场化改革方向,促进政府制度创新和企业技术与管理创新是城市转型升级的根本动力。     

外资银行进入与中国银行业绩效、市场集中度的变化

我国入世过渡期已经结束,银行业已全面对外开放.外资银行进入将对我国银行业绩效和产业组织结构带来重要影响.本文基于我国14家银行1996～2005年的面板数据,就外资银行进入对我国银行的短期影响进行研究.实证结果表明,国内银行对外资银行营业性机构数量增加反应不敏感,经营成本和盈利同外资银行市场份额的增加正相关,我国银行业市场符合结构-行为-绩效范式.本文就我国银行业应对外资银行冲击的方略提出建议,即通过与外资银行股权合作弥补我国银行业不足,通过金融控股公司模式实现综合经营以提高我国银行业国际竞争力,积极学习、借鉴外资银行新的金融产品和管理经验.     

PDE approach to valuation and hedging of credit derivatives

This paper presents a PDE approach in a Markovian setting to hedge defaultable derivatives. The arbitrage price and the hedging strategy for an attainable contingent claim are described in terms of solutions of a pair of coupled PDEs. For some standard examples of defaultable claims, we provide explicit formulae for prices and hedging strategies.     

Calibration of implied volatility for the exchange rate for the Chinese Yuan from its derivatives

Revised implied volatility curves and surfaces for the Chinese Yuan (CNY) exchange rate are obtained from market quotations for CNY non-deliverable options by solving an inverse problem of foreign exchange option pricing, which is calculated using a regularization approach in an optimal control framework. To take account of the market expectation for the CNY exchange rate, a stochastic adjusted factor is applied that follows a Vasicek model with parameters fitted from market quotations for CNY non-deliverable forwards. A well-posed numerical scheme is implemented.
