The The Political Institution Reforms Toward the Democratic Transition: A Case Study of the Electoral Reforms in Thailand

Abstract

This research aims to: 1) study the causes that led to the reform of Thailand's electoral system; 2) examine the effects of electoral system reforms on Thai politics; and 3) provide recommendations for electoral system reform to facilitate a democratic transition in Thailand. The study is a qualitative research approach, collecting data from primary and secondary documents related to electoral reforms under the 1997, 2007, and 2017 constitutions, and using content analysis. The argument of this study is that electoral reforms in Thailand have not merely constituted technical adjustments to electoral mechanisms; rather, they have functioned as political instruments through which ruling elites restructure power relations and shape political outcomes. Consequently, these reforms have failed to generate sustainable political stability and democratic consolidation.

The findings indicate that the electoral reform under the 1997 Constitution, which introduced a Mixed-Member Majoritarian (MMM) system, contributed to the formation of stable governments and facilitated the emergence of large, programmatic political parties. However, it simultaneously weakened parliamentary checks and balances and fostered the concentration of executive power. The 2007 Constitution retained the MMM system but modified its design to enhance opportunities for smaller parties. Nonetheless, these institutional adjustments did not resolve underlying structural political conflicts, leaving political stability fragile. In contrast, the 2017 Constitution adopted a Mixed-Member Apportionment (MMA) system aimed at curbing the dominance of large parties and dispersing legislative seats more proportionally. Yet this reform produced uncertain political outcomes and did not strengthen party institutionalization or foster consensus over the rules of the political game. The study, therefore, contends that Thailand’s democratic transition cannot rely solely on electoral system design. Instead, it requires an inclusive and participatory rule-making process capable of generating broad political consensus and promoting the institutional strengthening of political parties as essential foundations for democratic consolidation.
