Thai pro-productivity institutions – mainly the Office of Industrial Economics (OIE) and the Puey Ungphakorn Institute for Economic Research within the Bank of Thailand – conduct relevant productivity analysis using rich micro-data. However, data limitations, related to the frequency, coverage and statistical properties still hinder detailed productivity analyses. Thailand still lacks integrated data and insufficiently leverages the potential of administrative data, such as tax records, for statistics, notably through a Statistical Business Register. Addressing these challenges requires a more systematic approach to data exchange, both across pro-productivity institutions and with other agencies and external researchers, and facilitating a common business identification across data sources and agencies. These improvements would enhance the evidence base of policymaking by facilitating the analysis of a broader range of productivity-related indicators.
Moving towards a unique business identifier can bring direct benefits in terms of administrative procedures and enhance data linkages and productivity analysis. A unique business identifier system across administrations can bring direct economic benefits such as simplified administrative procedures for businesses. Simplifications can foster firms’ creation and business registration thereby helping to reduce informality. Besides these direct benefits, a unique business identifier can also facilitate inter-administrative exchange of micro-data and data linkages. The availability of a unique longitudinal identifier is also key to enhance the measurement and analysis of productivity and would facilitate the work of the recommended productivity council, its participating institutions and external researchers. Therefore, Thailand should define a common identifier, for legal entities and their local branches, to be used by all public institutions collecting data on businesses. Such an identifier could be based on an existing one or newly created. To achieve this, Thailand may need to assess and implement the necessary legislative changes (e.g. related to the establishment of the national identification system and the adaptation of registration procedures) and address challenges in the interoperability of data across agencies.
Thailand could more systematically leverage the potential of administrative data to produce business statistics and productivity analyses. Administrative data have emerged as a key source of information for statistical and economic analysis. Thailand could follow international best practices by leveraging this information more systematically for productivity analysis. Thailand may have to overcome legislative barriers to data sharing and modernise its statistical legislation for sharing and using such data for analysis. Using administrative data for statistical and economic analysis also requires the NSO to develop standard methodologies for repurposing administrative sources and integrating them into a structural business statistics system. In economies with a high level of informality, such as Thailand, regular surveys of the informal sector can complement administrative data, allowing for the identification and description of informal firms and those that hire informal workers. This enables the measurement of informality and its contribution to the economy, both in terms of labour input and overall output.
Developing a Statistical Business Register (SBR) can enhance data linkages, support the NSO in conducting business surveys and help develop official business statistics, including on business demography. The NSO could create and maintain an SBR by leveraging the existing common frame already used for the Industrial and Business Service Census and expand its coverage to include missing sources (such as tax records). Thailand should ensure that the NSO can rely on a strong mandate to collaborate with administrative data holders and overcome legislative barriers to share those data (see above). Thailand should ensure that the SBR is available to other institutions, including external ones, to leverage their expertise and conduct firm-level analysis (see the dissemination strategy discussed below). The NSO is in the process of updating its Statistical Master Plan and revising the National Statistical Act to enhance the country’s statistical infrastructure and address legal and institutional aspects to support effective data collection and dissemination. Such ongoing efforts align with these recommendations and should be continued.
Systematically monitoring a broader range of productivity indicators based on micro-data can inform policies. Existing analyses based on micro-data can serve as a foundation for the granular understanding of Thai productivity. To make a better use of these analyses for policymaking, Thai pro-productivity institutions along with the productivity council should build on the recommended productivity framework to consolidate the analysis around three dimensions. First, assessing levels and changes in productivity dispersion and heterogeneity across groups of firms (e.g. by firm size, age, ownership type, legal and registration status), together with determinants of productivity (e.g. related to innovation, ICT use and participation in international value chains) can strengthen the understanding of policy relevant questions and levers to boost productivity. Second, the framework should integrate the analysis of allocative efficiency, the extent to which resources are (re-)allocated towards more productive businesses and the state of competition in the economy. Finally, the analysis of business demography and creative destruction can provide key insights into how business creation, firm selection and exit contribute to productivity and more generally to economic dynamism. To conduct such analyses, Thailand could leverage the expertise of academics and technical experts from relevant institutions (such as NSO, PIER and OIE) as well as the secretariat of the recommended council.
Enhancing micro-data sharing and dissemination, particularly through a centralised data-sharing solution, can strengthen the evidence base on productivity. Following international practices, Thailand could strengthen the access to micro-data, not only for administrative purposes but also across the board for analysis. To this aim, Thailand can develop suitable data-sharing solutions, ideally centralising access to various micro-data, so that relevant users can easily and securely access these sources in one location. This would facilitate the publication of business statistics by Thai agencies and more broadly spur research on productivity. The NSO could coordinate the initiative and, in the short term, set up physical locations to provide access to adequately anonymised confidential micro-data. In the medium term, the objective will be to complement physical locations with remote access solutions and potentially include data collected by other institutions.
