苏州工业园区建设世界一流高科技园区的战略对策研究

近年来,苏州工业园区大力实施创新驱动发展战略,在打造世界一流高科技园区建设方面取得明显成效。文章在阐述园区当前发展现状的基础上,剖析园区创新发展存在的薄弱环节,进而提出建设世界一流高科技园区的战略对策。     

区域森林公园生态效率实证分析——以华东地区为例

采用Malmquist-Luenberger指数法对华东地区森林公园生态效率值进行测定的结果表明:从时序范围看,2011—2016年华东地区森林公园生态效率的均值为1. 006,但从2015年起进入下滑态势,说明华东地区森林公园的生态效率已经达到有效水平,但在扩大森林公园规模的同时忽视了对环境的有效保护以及资源的合理配置;从空间差异角度看,只有浙江与安徽两省的森林公园生态效率值未达到有效水平(分别为0. 851和0. 871),其余各省(市)的森林公园生态效率值均大于1,说明区域内存在一定的差异性;技术进步指数下降是制约MalmquistLuenberger指数提升的主要原因。由此可见,加大技术投入,促成交流合作机制,形成特有的竞争优势等,对提高区域森林公园生态效率是十分重要的。

湿地公园规划的生态服务功能影响预评价

鉴于湿地生态系统的特殊性和敏感性,科学地保护和利用湿地资源、合理地进行湿地利用规划,一直是相关学者所关注的问题;以安徽省北部淮河三汊河湿地为例,从水文调节、大气调节、水体净化、物质生产、文化功能、提供生境和生物多样性价值等方面采用替代成本法、恢复成本法、市场价格法和影子工程法对湿地生态服务价值进行经济核算;分别以生态服务功能价值的理论值(2152.9万元)和现状值(1982.7万元)为参考标准,进行湿地公园规划对湿地生态影响的比较分析,预评价湿地公园规划后的生态服务功能价值为2447.2万元,较理论值和现状值都高;在各项服务功能中,除物质生产功能影响为负值外,其它各项值均为正值,在水文调节、水体净化和文化功能方面变化值较大,因而,从生态服务功能角度考虑,可以认为公园规划具备合理性和可行性。     

Long-Term Performance Following Rights Issues and Open Offers in the UK

Abstract:  This study finds evidence of significant long-term underperformance following rights issues made during 1986-95 in the UK. The findings are resilient to a number of methodological controls. In contrast, our results for a smaller sample of open offers made during 1991-95 show strong positive performance over a 5-year post-issue period, implying that firms making open offers had better growth prospects than firms making rights issues. During 1986-90, a period when open offers were rarely used, firms appeared to be making rights issues to exploit overvaluation. However, this was not evident for rights issues made during 1991-95, a period when open offers were more commonly used.     

Stock Repurchase and the Role of Signaling： A Comparative Analysis between U.S. and China

This paper compares different methods used for stock repurchase and examines the role of signaling in the U.S. and China＇s capital markets. We find that the ways to buyback stocks are very different in the two countries. Most U.S. stocks are repurchased through open market and the signals sent to the market through open market repurchase are getting weaker. Even though stock repurchases are at their early stage in the Chinese stock market and the dominated way to buyback is through a negotiated repurchase agreement for non-floating shares, the power of signaling seems much stronger. Examining stock prices pre- and post-repurchase, we find that stock repurchase records an average abnormal return of 3.42% on the announcement date and 3.24% on the date of actual renurchase.     

Closing small open economy models

The small open economy model with incomplete asset markets features a steady-state that depends on initial conditions and equilibrium dynamics that possess a random walk component. A number of modifications to the standard model have been proposed to induce stationarity. This paper presents a quantitative comparison of these alternative approaches. Five different specifications are considered: (1) A model with an endogenous discount factor (Uzawa-type preferences); (2) a model with a debt-elastic interest-rate premium; (3) a model with convex portfolio adjustment costs; (4) a model with complete asset markets; and (5) a model without stationarity-inducing features. The main finding of the paper is that all models deliver virtually identical dynamics at business-cycle frequencies, as measured by unconditional second moments and impulse response functions. The only noticeable difference among the alternative specifications is that the complete-asset-market model induces smoother consumption dynamics.

The Theory of Socially Embedded Games: Applications and Extensions to Open and Closed Games

An earlier article, drawing on the mathematical theory of rules and rule complexes, extends and generalizes game theory (GGT). The theory has been used to conceptualize and analyze diverse social relationships, roles, and games as particular types of rule complexes.For instance, a social role, as a major basis of a parent's action in a game, consists of at least four key components – which are mathematical objects – in the determination of action: value complex, model of reality (including beliefs and knowledge bases), a repertoire of acts, routines, programs, and strategies, and modality, a role-specific algorithm for determining or generating action in game settings. This article applies and extends GGT in analyses of a market bargaining game (a type of open game) and of the classical game of prisoners' dilemma (a type of closed game). The applications show the concrete effects of social embeddedness on game structuring, game interaction patterns and outcomes, and social equilibria.
