湘粤赣省际边界禁止开发区域生态旅游环境质量综合评价

生态旅游环境质量评价是主体功能区中禁止开发区域发展生态旅游的前提。选取湘粤赣省际边界的丹霞山、莽山、苏仙岭和三百山等具有代表意义的禁止开发区域为研究对象,通过构建生态旅游环境质量评价的压力—状态—响应模型,定量分析了该边界区4个禁止开发区域生态旅游活动对其自然、经济、社会环境质量的影响,以及由此产生的生态环境压力及其响应状况。研究认为,湘粤赣边界禁止开发区域生态环境总体质量良好,但各指标质量发展不均:①生态旅游活动对湘粤赣边界禁止开发区域生态环境造成的整体压力处于中低压状态;②生态环境承载力能应对目前生态旅游发展对其产生的压力,这为湘粤赣边界各禁止开发区域发展生态旅游提供了较为广阔的发展空间和重要保障;③经济、社会生态环境指标质量的提高和环保意识培养是禁止开发区域生态环境建设的重点。评价结果是湘粤赣边界禁止开发区域研究生态旅游发展机制和模式前提和基础。     

利益相关者视角的企业形成逻辑与企业边界分析

本文将企业的形成视为利益相关者集体选择的结果,由两个层次的集体选择决定。第一层次是所有可能的利益相关者对企业契约和交易契约的选择,企业契约的选择者将构建企业并拥有企业所有权。第二层次是拥有企业所有权的利益相关者对企业控制权和合作剩余分享方案的选择。第二层次集体选择的可能集是第一层次集体选择中个体理性的约束条件,本文借助不等式组推导了第二层次集体选择的可行集。在对企业形成逻辑进行分析的基础上,本文结合实例探讨了企业的所有权边界和经营边界。最后,总结提出了"利益相关者集体选择的企业观",并对其应用前景进行了展望。     

伙伴型政府间关系：中国府际治理的趋向

我国当前政府间关系因条块纷争、城乡矛盾而呈现失序状态,中央部委、地方政府及其部门之间政策冲突屡屡发生。从法治环境、协商民主、信息共享、多方参与、平等信任角度解析,可见建构伙伴型府际关系的必要。伙伴型政府间关系尊重地方政府的选择,避免采取自上而下的强令措施,注重跨区域跨流域跨部门的政府间合作,意图建立政府间超越等级、定位清晰、平等对话、合作共赢的政策网络,为我国的政府间关系发展及政策制定提供路径指向。     

在网络经济下的企业边界的研究——基于能力理论的视角

网络经济的到来,企业的经营理念和组织结构都发生了极大的变化,使得传统的交易成本理论对企业边界的解释显得有些不足。通过梳理主流企业边界理论的相关观点,阐释了能力理论对于分析网络经济下企业边界的适用性。在此基础上,从核心能力、附属能力和基本能力三个纬度对企业的边界进行了探讨。     

套牢问题与企业边界的关系探讨

关于企业边界的研究,最有影响力的工作集中于套牢问题。目前为止,至少存在三种学派对此做出了研究:契约经济学流派、交易费用经济学流派、新产权经济学流派。本文旨在综述这三个主要学派的观点,并比较它们的研究切入点和彼此之间的不同点并进行评论。研究表明,三个学派基本认同套牢问题产生的根源为:人的有限理性、契约不完全以及资产专用性投资,但是在治理措施上分别产生了契约治理、长期动态(声誉考虑)治理、组织治理等。     

The representation of American options prices under stochastic volatility and jump-diffusion dynamics

This paper considers the problem of pricing American options when the dynamics of the underlying are driven by both stochastic volatility following a square-root process as used by Heston [Rev. Financial Stud., 1993, 6, 327–343], and by a Poisson jump process as introduced by Merton [J. Financial Econ., 1976, 3, 125–144]. Probability arguments are invoked to find a representation of the solution in terms of expectations over the joint distribution of the underlying process. A combination of Fourier transform in the log stock price and Laplace transform in the volatility is then applied to find the transition probability density function of the underlying process. It turns out that the price is given by an integral dependent upon the early exercise surface, for which a corresponding integral equation is obtained. The solution generalizes in an intuitive way the structure of the solution to the corresponding European option pricing problem obtained by Scott [Math. Finance, 1997, 7(4), 413–426], but here in the case of a call option and constant interest rates.     

Boundary spanner turnover in professional services: Exploring the outcomes of client retention strategies

Abstract

Studies suggest that the termination of the interpersonal relationship between boundary spanners at buyer and seller firms can have a damaging effect on the inter organisational relationship. Few studies have addressed this issue in detail, but those that do, advise supplier firms to implement strategies such as service teams and boundary spanner rotation to lessen the negative effects of boundary spanner turnover. By creating multiple bonds between the two firms, dispersing client-specific knowledge widely throughout the supplier firm, and preventing the development of a close bond between buyer and seller boundary spanners, individual interpersonal relationships become less important. However, a review of relationship literature on trust, commitment, social bonds, and knowledge suggests the potential for negative outcomes from the implementation of the strategies. Using case studies and one-to-one interviews with design buyers and their agencies, this paper explores the outcomes of the two strategies, and the contexts in which these outcomes occur. Adopting a critical realist approach, findings are presented in the form of context–mechanism–outcome models. Agency size, agency culture, client experience, and boundary-spanner autonomy are amongst the contexts that influence the outcome of strategy implementation.     

The link between intraday signals and call warrant mispricing

This study proposes a linkage between intraday variables (signal amounts and signal duration) and the mispricing of Taiwan call warrant prices, based on the lower boundary condition of Merton [1973. Theory of rational option pricing. Bell Journal of Economics and Management Science, 4(1), 141–183] as modified by Galai [1978. Empirical tests of boundary conditions for CBOE options. Journal of Financial Economics, 9(2), 321–346]. Trading mispriced call warrants associated with a riskless hedging strategy over the period January 2004–December 2005 on average produces abnormal profits after taking into account transaction costs, as indicative of an inefficient market.     

省际边界区域发展的空间结构优化研究——以粤闽湘赣省际边界区域为例

从粤闽湘赣省际边界区域整体的角度,以构建多中心城市区域的理念,提出了粤闽湘赣省际边界区域空间结构优化的具体构想,即以韶关、赣州、郴州成长三角为整个省际边界区域的核心,以其它6个中心城市为市域的核心,以经济基础好或交通条件好的县(市)城区作为县域的中心,构建7条城镇发展聚合轴和拓展轴作为城镇、交通和产业的聚集和依托轴,以形成城市空间功能互补,集约紧凑发展,绿色空间穿插相融,高度协调、网络化的多中心城市区域,以整体的优势参与珠三角城市体系分工,并力争在区域分工中占有优势。     

交易成本内部化与模块化组织边界变动

文章基于交易成本理论,对模块化变革引起的交易成本内部化及模块化组织边界变动问题进行了探讨。首先,识别并界定了模块化组织边界,认为模块化组织边界是指依据模块化组织基本架构和主导规则所建立起来的关系网络的界限范畴。其次,基于模块化"竞合机制",指出了模块化组织交易成本内部化趋势,集中体现为：信息提升强化了组织运行的不确定性、频繁更替成员企业促使了组织内部合作的交易化、规则化约束强化了资产专用性的锁定。进一步地,厘清了交易成本内部化而引起的模块化组织边界变动的实质,即组织会在交易契约与协作契约之间进行二次选择,直到最优契约组合模式的出现。最后,对模块化组织边界变动下的治理问题进行了探索性分析。
