城市化进程中的社区建设模式探索——以长沙市咸嘉新村为例

城市化进程中的社区建设问题是当前一大热点问题，其模式选择也备受学术界关注。本文在分析国内外社区建设模式优劣的基础上，以长沙市咸嘉新村为实证研究，围绕社区建设主体之间的利益分配和相互作用展开研究，通过构建社区建设的三方“博弈模型”，探索出了“G—D—P联合建设”的新模式，以期为我国城市化进程中的新型社区的建设与完善，旧有社区和城中村的改造提供可行性方案。     

Diversification,Performance, and the Corporate Life Cycle

This paper investigates the relation between the extent of diversification in firms and their performance at different life cycle stages. To illustrate the joint endogeneity of diversification and performance, we treat both the extent of diversification and firm performance as endogenous variables in a simultaneous equation system. Empirical results reveal that corporate diversification erodes firm value. Overall, firms in their growing stages experience a significant diversification discount; however, mature firms do not show such findings. Although unrelated diversification leads to trading at a discount in all growing and mature firms, conversely, related diversification exhibits an evident premium in mature firms.     

Cooperation In R&D With Spillovers And Delegation Of Sales ∗

Cooperation in several phases of the innovation process is viewed by antitrust authorities with suspicion. They face the dilemma between providing the right incentives for the appro-priability of returns to R&D and the risks of diminishing product market competition. The current legislation in the European Union and the United States gives special treatment to cooperation in R&D and the joint exploitation of results (extended cooperation).

We study several collusive regimes for a class of examples in which vertical relations are explicitly introduced. Regarding antitrust policy implications we fmd that: a) there is an ana-lytical justification to a ‘rule of reason’ treatment for extended cooperation in research joint ventures and, b) individual exemptions, though restrictive of competition, might be welfare improving.

Introducing Environmental Management in the Hotel Industry

Summary

The hotel industry in Jamaica, like so many other tropical destinations, markets itself on the “3-Ss”-sea, sun, and sand. Hotels ring the north coast of the island in four main resort areas (i.e., Negril, Montego Bay, Ocho Rios, and Port Antonio). Located in sensitive coastal ecosystems, most of Jamaica's hotels face the challenge of reducing the environmental impact of their operations while meeting the increasing demand of a growing tourism industry.

This article presents a case study of the introduction of environmental management practices and systems in the hotel industry in Jamaica over the past 3 years to provide an answer to the environmentally sustainable tourism challenge. It describes the programmatic approach, the results at both the property and industry level, and the lessons learned in replicating the approach to other tropical tourism destinations in the Caribbean and Latin America.     

Big Five Audits and Accounting Fraud*

We examine the association between Big Five audits and the incidence of accounting frauds allegedly committed by U.S. public companies between 1981 and 2001. Many commentators argue that the prominent financial reporting failures that led to major corporate governance reforms cast serious doubt on whether the large public accounting firms continue to supply relatively high‐quality audits, especially in recent years. However, in unmatched and matched samples, we provide strong, robust evidence that fraudulent financial reporting becomes less likely with the presence of a Big Five auditor. Importantly, time‐series tests suggest that the Big Five are consistently associated with a lower incidence of fraudulent accounting, including in the last five years of our sample period when the number of frauds soared. Moreover, we find evidence implying that these relations are causal rather than an artifact of endogeneity in auditor choice.     

A comparative study of human resource management practices in international joint ventures: the impact of national origin

This paper presents a comparative study of the effects of national origin, a company's strategic orientation and its investment profile on preference for the application of human resource management (HRM) practices as conducted in international joint ventures (IJVs). The approach extends understanding by offering a broader exploration of how national differences generate additional barriers that impact on specific HRM practices. The evidence from the study presented suggests that there is little support for national origin being a major independent influence. National distinctiveness does define the types of integration between parent companies and IJVs, but these collaborations do not necessarily reflect any specific national institutional bias. Examination of eighty-seven IJVs suggests that IJV management has a high degree of organizational autonomy in the implementation of a company's task-related inputs regardless of the national background of the foreign partner. The presence of a company's task-related effects on HRM practices plays a significant contextual role where the major attributes are the technology, management development and the compatible use of an IJV's resources. The results confirm that there is little evidence to suggest that partner-related influences derived from the partners' complementary resources and competences in the field of HRM development that are national origin specific have had significant influence over HRM development in the IJVs studied.

Managing Competing Institutional Logics in Public–Private Joint Ventures

Abstract

Cross-sector inter-organizational partnerships, alliances and networks have become extremely popular. Yet, we may expect competing societal-level institutional logics to play an important role in cross-sector alliances, hence making their management central to alliance success. This article responds to the general research question: How do participants of public–private joint ventures manage competing institutional logics? Based on in-depth interviews we empirically characterize two competing logics in a cross-sector collaborative and identify two practices used to cope with them.     

Contract,cooperation, and performance in international joint ventures

This study examines how contract, cooperation, and performance are associated with one another within international joint ventures (IJVs). We argue that contract and cooperation are not substitutes but complements in relation to IJV performance. An IJV contract provides an institutional framework guiding the course of cooperation, while cooperation overcomes the adaptive limits of contracts. Our analysis of 293 IJVs in a dynamic market demonstrates that previous cooperation bolsters contractual adaptability, which in turn nurtures current cooperation between the same partners. We find that contract completeness and cooperation drive IJV performance both independently and interactively. When contracts are more complete, cooperation contributes more to performance. Contract and cooperation differ in their quadratic effects such that the contribution of contract completeness to performance declines as completeness increases but the contribution of cooperation remains linear.
