Thailand has climbed one spot to 28th on the Institute for Management Development’s 2021 world competitiveness rankings, three spots behind ASEAN neighbor Malaysia and nine spots ahead of Indonesia in the global rankings. 

Switzerland-based IMD attributed Thailand’s gains to improvements in labour market indicators, a low government deficit and recently enacted pro-business legislation; the organization also noted Thailand’s gains in scientific infrastructure, including an increase in scientific academic research publications, confidence express by Thai business managers on the collaboration between academia and the private sector and increased protection of intellectual property rights.  

Thailand’s improved showing on the global stage will likely lead to an increased interest in the country’s intellectual property regime and practice, which will provide more opportunities for new law firms to work their way into the market. Already, new firms like The Legal and iLAWASIA, and regional firms like S&O IP and Rajah & Tann, are making inroads into what used to be a comfortable handful of law firms for others to compete against.
