张家界发展生态旅游的SWOT分析及策略

生态旅游作为一种新兴的旅游形式，已引起了旅游界的广泛重视，它必将成为21世纪国际国内旅游业发展的主导形式。运用SWOT法方析，发现张家界发展生态旅游，优势有：良好的发展前景、区住优势和资源优势；劣势有：资金不足、基础设施落后、旅游产品单一、形象不突出等；机会有：生态旅游在国内外的蓬勃发展、有助于发展生态旅游的国际国内大环境逐步形成；挑战有：生态的脆弱性、本地其他旅游资源的屏蔽作用和生态旅游开发在我国处于不成熟阶段等。基于以上分析，提出了张家界生态旅游发展的“S＋O”战略、“S＋W”战略和“O＋T”战略。     

住宅用地基准地价的容积率系数修正新方法

容积率修正系数编制是土地评估领域探讨的热点之一。提出了先构建容积率、因素总分值与地价关系的地价模型,进而编制分级别的住宅用地容积率修正系数的新方法,并以北海市为例进行实证研究。研究表明:地理加权回归模型的拟合度明显优于最小二乘法,便于据此编制更精准的分级别容积率修正系数表;该方法引入因素总分值规避了传统区域修正方法的主观任意性问题,便于计算机进行批量快速处理,保证了编制的容积率修正系数的可靠性,在实践中行之有效。

How regulatory changes affect IPO underpricing in China

This paper examines the underpricing of IPOs in the Chinese A-share market during the period 1992–2006. Since its inception, the Chinese IPO market has transformed from a tightly-controlled system to a more market-oriented system. Reforms include the abolishment of listing quotas and fixed issue price determination; allowing for more market participation in IPO pricing. The regulatory changes of Chinese IPO market, though improving over time, actually are not monotonic. The regulatory framework started from over-restrictive to over-unrestrictive, then fine-tuned with additional restrictions. This study documents the regulatory reforms during the sample period and investigates how these regulatory changes affect IPO underpricing in China. During this period, we find that Chinese IPOs exhibit a huge underpricing. The size of the underpricing, however, decreases over the sample period. This study further finds that the IPO pricing method before the regulatory changes, which was based on a fixed P/E ratio pre-determined by the regulators, contributed significantly to the IPO underpricing in China. After adopting a series of regulatory reforms allowing underwriters discretion in the determination of issue price, this regulatory underpricing component vanishes. This study has policy implications in demonstrating the impacts of regulatory frameworks on IPO underpricing.     

秉持“两型社会”理念传播城市形象——以长株潭城市群为例

近年来,随着中国经济的快速发展及其国际地位的不断提高,我国地方政府已经有了越来越强的城市形象意识,各种形式的对外传播活动也相继展开。但是,对中国城市而言,城市形象传播毕竟是一个全新的实践领域,许多规律性的东西我们还没有把握好,一些观念与思路也没有调整到位,这在很大程度上影响着我国城市形象塑造与传播的效果。为此,我们借助地理传播学以长株潭城市群作为样本,利用网络数据库建立组合矩阵模型进行量化分析认为,长株潭秉持"两型社会"理念传播城市形象的成功做法和经验颇值得借鉴。     

When Do Analysts Adjust for Biases in Management Guidance? Effects of Guidance Track Record and Analysts’ Incentives

Prior research indicates that analysts do not fully adjust for the general downward bias in earnings guidance issued by management. We report the results of two experiments designed to investigate how guidance track record and analysts’ incentives jointly explain the extent to which analysts adjust for guidance bias. Our results suggest that analysts with accuracy incentives adjust for management’s track record of downwardly biased guidance when the bias is relatively small (one cent), but those with relationship incentives do not. Furthermore, the difference in adjustment is larger when the bias track record is inconsistent than when it is consistent. Also, when guidance bias is larger (two cents) relative to smaller (one cent), analysts with relationship incentives partially adjust, as they appear to strike a balance between accuracy and their desire to please management. These findings hold implications for investors, regulators, and the interpretation of prior research.     

论汽车企业工程零件清单(EPL)的管理方法

工程零件清单(EPL)用于向公司的其他业务部门传递开发车辆的零件信息,其准确性和完整性影响整个车辆开发过程。因此,EPL从项目初期建立模板到EPL冻结发布,如何保证工程零件清单的准确性至关重要。文章介绍了在整车开发流程(VDP)中的重要几个时间节点EPL的管理方法。     

基于线性调频再扩频的ZigBee网络中WiFi干扰避免方法

针对ZigBee网络与WiFi网络共享2.4 GHz频段造成的信道干扰问题，提出了一种基于线性调频再扩频技术的ZigBee网络中WiFi干扰避免方法。该方法根据检测接收数据包中的链路质量指示值计算ZigBee网络链路通信质量，将链路通信质量作为判断WiFi网络干扰强弱的依据：当链路通信质量低于最低容忍阈值时，利用线性调频再扩频技术展宽ZigBee网络信道射频信号频谱，反之则保持原有射频信号频谱带宽传输数据。Matlab仿真结果表明，该方法能明显提升ZigBee网络抗击WiFi信号干扰的能力，具有较好的实际应用价值。
