This paper aims to contribute to this literature gap, firstly by demonstrating how city-regions are functional economic areas which can be empirically studied. Secondly, by analyzing the Vietnamese legal framework using the Hanoi Capital Region and the Ho Chi Minh City Region as case studies, this paper presents arguments that City-region development in Vietnam is highly normative and politically guided. | VNU Journal of Science Economics and Business Vol. 36 No. 2 2020 52-66 Original Article Analysing City-Regions in a Vietnamese Context An Overview of Concepts Definitions and Development Policy Implications Le Minh Son Vietnam Institute for Development Strategies 65 Van Mieu Street Dong Da Hanoi Vietnam Received 01 April 2020 Revised 08 May 2020 Accepted 11 June 2020 Abstract In recent years Vietnam has made forward-looking steps in endorsing and promoting City-region development with appropriate vision and leadership.
