Contingencies influencing the management accounting practices of Estonian manufacturing companies

Having regained independence in 1991, Estonia has undergone fundamental political and structural changes over the last decade, which have also affected the operation of its companies. This paper examines the management accounting practices of Estonian manufacturing companies, exploring the main impacts on them within a contingency theory framework. The methodology comprises an analysis of 62 responses to a postal questionnaire survey carried out among the largest Estonian manufacturing companies. It is comparatively infrequently that Estonian manufacturing companies have made improvements in their cost accounting methods, although the majority of respondents appear to acknowledge the importance of these practices in finding and lowering real product costs and modernizing the cost accounting systems. The effectiveness of an accounting systems’ design depends on its ability to adapt to changes both in external circumstances and internal factors. We have found some evidence that changes in cost and management accounting practices are associated with shifts in the business and accounting environment as external contingencies, and with those in technology and organizational aspects as internal contingencies. This research aims on the one hand to confirm earlier findings related to the ‘contingent factors’ that influence management accounting and on the other, to identify possible new factors, such as, for example, the legal accounting environment and shortage of properly qualified accountants.     

Corporate Governance: Factors Influencing Voluntary Disclosure by Publicly Traded Canadian Firms*

We report on the comprehensiveness of voluntary corporate governance disclosures in the annual reports and management information circulars of Toronto Stock Exchange (TSE) firms. We focus on disclosure of the corporate governance practices implemented by our sample of TSE 300 firms vis‐à‐vis the 14 guidelines set out in the TSE's report on corporate governance Where Were the Directors? Our analysis indicates that only a very few firms disclose that they have fully implemented the TSE guidelines, and that the extent of disclosure of corporate governance practices implemented varies widely among the firms. We then test factors associated with the comprehensiveness of such disclosures and the choice of disclosure medium using simultaneous equations multivariate analysis. We also assess the influence of publicized corporate governance failures on disclosure. Overall, our results suggest that the choices of disclosure medium and the extent of disclosure are made concurrently, and are influenced by the strategic considerations of management.

国有建筑企业中的人力资源开发与管理

在现代管理中人力资源开发与管理日益成为企业的一项战略性工作，赢得了人才就赢得了企业的持续发展的后劲。本通过选择一个传统的建筑行业为出发点，结合笔较长时期在该行业从事人力资源管理工作的实际，从建筑企业自身具具的特殊工作性质来概述人力资源开发与管理工作的现状、面临的难题，分析其原因、并着重从具体的人员培训、绩效考核、薪酬管理以及企业化建设几个方面来提出如何建立、实行高效的人力资源开发与管理体制，从而为企业的发展提供强大的人才保障。     

基于供应链管理的房地产开发企业合伙模式研究

基于供应链的思想，传统制造业中的各个企业被看作整个供应链中的某一环节，供应链管理使企业集中优势资源与精力创造特殊价值，提高自身竞争能力并带动相关企业发展。房地产开发企业作为自身行业中的“集成制造商”，应该充分借鉴供应链管理的思想，大力发展与相关合作对象的伙伴关系，基于其独特的供应链的内部集成，建立合适的合伙模式，以达到降低开发成本、提高项目品质、增强企业核心竞争力的目标。
