Purpose

Construction labor productivity (LP) is the key element in forming the success of construction projects. Numerous studies on the topic of critical success factors (CSFs) within construction LP have been conducted, but the results have rarely emphasized developing factors related to managerial function behaviors (MFBs) and examining its relationship with construction LP, a key criterion for measuring construction effectiveness; these less researched topics were the aims of this study.

Design/methodology/approach

The empirical research studies were designed to develop managerial behavior's attributes based upon a literature adaptation and focus group studies (FGSs). Then, the causal relationships between MFBs and LP were examined by drawing on project-specific data collected from 195 completed construction projects in Vietnam, which was to the approach to an exploratory factor analysis (EFA) and Bayesian model averaging (BMA) technique.

Findings

The findings reveal that the MFBs' attributes were organized into a four-factor MFB framework: “cooperation emphasis (COOP),” “people orientation (PEOP),” “commitment emphasis (COMT)” and “leadership promotion (LEAD).” The findings reveal that COOP, PEOP and COMT have significant effects on LP.

Originality/value

The success of this approach is expected to broaden academic's horizons of factors affected LP and suggest a useful tool for supporting the project management professionals in enhancing construction LP and sustainability.

项目管理职能行为对施工劳动生产率的影响建模

目的

建筑劳动生产率（LP）是形成建筑项目成功的关键因素。已经对施工 LP 中的关键成功因素 (CSFs) 主题进行了大量研究，但结果很少强调与管理功能行为 (MFB) 相关的发展因素以及检查其与施工 LP 的关系，这是衡量施工有效性的关键标准; 这些研究较少的主题是本研究的目的。

设计/方法/方法

实证研究旨在根据文献改编和焦点小组研究 (FGS) 开发管理行为的属性。然后，通过利用从越南 195 个已完成的建设项目中收集的项目特定数据来检查 MFB 和 LP 之间的因果关系，这是探索性因素分析 (EFA) 和贝叶斯模型平均 (BMA) 技术的方法。

发现

研究结果表明，MFB 的属性被组织成一个四因素 MFB 框架：“合作重点（COOP）”、“以人为本（PEOP）”、“承诺重点（COMT）”和“领导力提升（LEAD）”。研究结果表明，COOP、PEOP 和 COMT 对 LP 有显着影响。

原创性/价值

这种方法的成功有望拓宽学术界对影响 LP 的因素的视野，并为支持项目管理专业人员提高施工 LP 和可持续性提供有用的工具。
