WHAT IS A PROFESSIONAL SERVICE FIRM? TOWARD A THEORY AND TAXONOMY OF KNOWLEDGE-INTENSIVE FIRMS.
提出专业服务公司的三个核心特征（知识密集、低资本密集、专业化劳动力），并据此将知识密集型企业分为四类，分析其组织结果差异，提醒研究者不要混淆专业化和知识密集的影响。
I develop a theory of the distinctive characteristics of professional service firms and their organizational implications. I identify three distinctive characteristics—knowledge intensity, low capital intensity, and a professionalized workforce—with which I propose a taxonomy of four types of knowledge-intensive firms whose varying degrees of professional service intensity generate different organizational outcomes. The analysis highlights the danger of conflating the implications of professionalization with those of knowledge intensity and calls for comparative research across a wider range of professional services.
