In recent years, the use of administrative data has been attracting attention in the field of economics. Previously, the mainstream data used for research was collected specifically for statistical purposes, such as the national census. In contrast, administrative data consists of information collected by the government for its own operations. A vast amount of data, such as pension payment records and tax records, lies dormant within administrative agencies. In other countries, the use of administrative data for research has been progressing since the 2000s.

The greatest advantage of administrative data is that it is a raw record of actual economic activity. For example, pension records provide realistic data on the job market—such as job change history, salary amounts, and periods of leave—which are difficult to investigate through statistical surveys.

I myself have been conducting research since 2011 using import and export declaration records from Mexican customs. The import and export declarations submitted to customs record detailed transaction information, such as who sold what product to whom, when, at what price, and in what quantity. Using this data, my research theme is to understand the characteristics of transactions between companies.

When asked why Mexico, one reason is that in 2011, only a few countries opened their import and export declaration records for research, and Mexico was one of them. Meanwhile, the importance of our research was recognized in Mexico, and we received a domestic paper award in Mexico in 2015. In this way, by opening up administrative data, researchers from all over the world gather to study the important economic issues of that country, creating a positive relationship between administration and academic research in many nations.

With the start of the Reiwa era, the research use of administrative data has begun in Japan as well. Since 2022, the use of tax records from the National Tax Agency and import/export declaration records from Customs has started as joint research with the National Tax College and the Policy Research Institute, respectively. Five researchers from 春雨直播app, including myself, are participating in the use of import/export declaration records.

When using administrative data, attention must be paid to the protection of recorded personal information. In the case of import/export declaration records, data is prohibited from being taken out of PCs located in Kasumigaseki, and the content of the analysis is limited to things that do not identify individuals or companies.

Along with the joy of being able to participate in this new initiative, I feel a responsibility to make the research a success and pave the way for the future. It looks like my days of commuting to Kasumigaseki between classes will continue.
