中国人力资本水平与FDI技术溢出关系研究

针对1985-2009年间中国人力资本水平和FDI技术溢出进行VECM模型检验结果表明,我国人力资本水平与FDI技术溢出存在长期稳定关系,但短期关系不显著。从动态层面看,FDI技术溢出变化对我国人力资本水平有显著的正向影响,但我国人力资本水平变化对FDI技术溢出的正向影响程度较弱。     

全流通环境下中国银行业的市值评估——来自国内上市银行的经验数据

银行业的价值评估对于推进金融体制改革存在重要意义,本文从价值评估文献综述入手,建立了一个两步骤的统计学模型,首先通过因子分析得到影响银行价值的主要成分,然后通过多元线性回归检验银行规模、经营业绩和流动性对银行股票价格的影响,实证结果显示:股权分置改革并未如预想的那样对股票价格有明显影响,中国银行业主要盈利来自于存贷款利差收入。     

乡村旅游区域合作发展模式研究——以环洪泽湖地区为例

目前国内乡村旅游业的发展尽管速度较快,农业观光园、农家乐、采摘节等乡村旅游形式在各地大量涌现,但是与发达国家相比仍处于起步阶段,各旅游目的地之间缺乏统一规划、资源特色不明显、配套服务设施缺乏、经营模式单一等问题突出。区域旅游合作对整合资源、统筹城乡发展、丰富区域旅游类型、满足都市居民对乡村旅游的需求,提升其综合发展水平是一条可行的途径。本文基于对乡村旅游发展现状的研究,提出了包括空间发展、运营模式、产品开发、策划营销及支持系统在内的区域旅游合作发展模式,以期对乡村旅游的发展有所裨益。     

自归理论与递归方法之数据质量辨识能力比较(英文)

分别应用自归理论和递归方法,采用同一组隧道拱部沉降实测数据进行对比分析证明,自归理论的数据质量辨识与数据筛选能力强于递归方法,宜于原始数据精度要求较高的、高等级项目监控的数据处理;而递归方法由于抗干扰性能强,在对参与数据质量没有较高要求时使用,亦不失为一种可行的措施。     

日本政府投资、民间投资和产业资本收益之间关系的实证分析

本文基于日本的统计数据,利用VAR模型和格兰杰因果关系检验方法,研究政府部门投资、民间部门投资和全产业总资本收益率之间的相互作用。VAR模型分析表明,政府投资对民间投资的影响比较大,两者对全产业总资本收益率的影响都很大且政府投资的影响远远大于民间投资,这些影响关系都较复杂。格兰杰因果关系检验表明,政府投资变化是民间投资变化的格兰杰原因,两者分别是全产业总资本收益率变化的格兰杰原因,而这些变量之间不存在相反方向的格兰杰因果关系。     

“两缺口”模型中国悖论的成因

利用外国直接投资(FDI)来促进经济增长是我国的一个重要发展战略,但"两缺口"模型已经不能对此进行解释。由于生产要素的国际流动和国际贸易统计体系的颠覆,改变了"两缺口"模型成立的初始条件,而中国特殊的文化传统、转轨时期不完善的经济和社会制度以及对引资作用片面和静态的认识促成了"两缺口"模型在中国的悖论。     

Assessing time-varying stock market integration in Economic and Monetary Union for normal and crisis periods

In this paper, we examine the stock market integration process amongst 17 Economic and Monetary Union (EMU) countries from January 2002 to June 2013 over a normal period as well as for the Global Financial Crisis (GFC) and Eurozone Debt Crisis (EDC) periods. We classify the economies in three groups (A, B and C) based on their GDP to examine whether the economic size influences financial integration. Seven indicators are used for the purpose, namely, beta convergence, sigma convergence, variance ratio, asymmetric DCC, dynamic cointegration, market synchronisation measure and common components approach. The results suggest that large-sized EMU economies (termed as Group A) exhibit strong stock market integration. Moderate integration is observed for middle-sized EMU economies with old membership (termed as Group B). Small-sized economies (termed as Group C) economies seemed to be least integrated within the EMU stock market system. The findings further suggest presence of contagion effects as one moves from normal to crisis periods, which are specifically stronger for more integrated economies of Group A. We recommend institutional, regulatory and other policy reforms for Group B and especially Group C to achieve higher level of integration.     

Decision-making in incomplete markets with ambiguity—a case study of a gas field acquisition

We apply utility indifference pricing to solve a contingent claim problem, valuing a connected pair of gas fields where the underlying process is not standard Geometric Brownian Motion and the assumption of complete markets is not fulfilled. First, empirical data are often characterized by time-varying volatility and fat tails; therefore, we use Gaussian generalized autoregressive score (GAS) and GARCH models, extending them to Student’s t-GARCH and t-GAS. Second, an important risk (reservoir size) is not hedgeable. As a result, markets are incomplete which makes preference free pricing impossible and thus standard option pricing methodology inapplicable. Therefore, we parametrize the investor’s risk preference and use utility indifference pricing techniques. We use Least Squares Monte Carlo simulations as a dimension reduction technique in solving the resulting stochastic dynamic programming problems. Moreover, an investor often only has an approximate idea of the true probabilistic model underlying variables, making model ambiguity a relevant problem. We show empirically how model ambiguity affects project values, and importantly, how option values change as model ambiguity gets resolved in later phases of the projects. We show that traditional valuation approaches will consistently underestimate the value of project flexibility and in general lead to overly conservative investment decisions in the presence of time-dependent stochastic structures.     

我国居民杠杆率现状及影响因素研究

近年来,我国居民部门杠杆率的快速上升引起社会各界关注。本文使用货币信贷和城镇储户调查数据,对我国居民部门杠杆率和偿债能力现状进行了分析,并运用各省住户贷款数据计算各省的居民杠杆率,使用面板数据模型对居民杠杆率上升的原因进行了实证分析。结果表明,房价的快速上涨和住房销售的增长都对居民部门杠杆率的上升有显著正向影响,其中房价上涨的影响程度更大。此外,金融发展水平和老年人抚养比对居民杠杆率有正向影响,少年人抚养比对居民杠杆率有负向影响。
