Political party and party system institutionalization in Southeast Asia: lessons for democratic consolidation in Indonesia, the Philippines and Thailand.

Is a higher degree of party and party system institutionalization positively correlated with the consolidation of democracy, defined here as the prevention of democratic breakdown? In order to answer this question, it is useful to compare different levels and types of institutionalization in three Southeast Asian electoral democracies. Institutionalized party systems are characterized, according to Mainwaring and Torcal, by 'stability of interparty competition.' Moreover, the distinction made by Levitsky ('value infusion' versus 'behavioural routinization') with reference to the institutionalization of individual parties will be employed. The empirical research of this paper finds that most Indonesian parties are better institutionalized than those in the Philippines and Thailand with reference to 'value infusion.' In addition, the interparty competition is more stable in Indonesia. Therefore, the probability of a collapse of the party system in the Philippines and Thailand is much higher. This, in turn, renders the democracies in these countries more fragile and prone to political crises or even sudden breakdowns. The early organizational consolidation of social cleavages, such as in Indonesia, enhances institutionalization. A few of the most important parties are socially rooted and have strong linkages to civil and/or religious organizations. Furthermore, the relationship between central and local elites appears to be essential: strong bosses or cliques undermine institutionalization in the Philippines and in Thailand, respectively. However, in recent years there has also been a tendency towards convergence. There are signs of regression in Indonesia, such that the future of the party system is open to question. This article calls for caution with respect to the stated causal relation between institutionalization and democratic consolidation, and it questions some aspects of the concept.
