Abstract
This paper reports on exploratory research carried out into the processes of policy‐making, and in particular health sector reform, in the health sector of Thailand. It is one of a set of studies examining health sector reform processes in a number of countries. Though in the period under study (1970–1996) there had been no single health sector reform package in Thailand, there was interest in a number of quarters in the development of such an initiative. It is clear, however, that despite recognition of the need for reform such a policy was far from being formulated, let alone implemented. The research, based on both documentary analysis and interviews, explores the reasons underpinning the failure of the policy process to respond to such a perceived need. The research findings suggest that the policy formation process in Thailand successfully occurs when there is a critical mass of support from strategic interest groups. The relative power of these interest groups is constantly changing. In particular the last two decades has seen a decline in the power of the bureaucratic élites (military and civilian) and a related rise in the power of the economic élites either directly or through their influence on political parties and government. Other critical groups include the media, NGOs and the professions. Informal policy groups are also significant. A number of implications for policy makers operating under such circumstances are drawn. Copyright © 2000 John Wiley & Sons, Ltd.
