The general objective of this project is to develop tools and solutions that turn value-added tax (VAT) records into an information system that can support evidence-based policy making and the development of regions, industries and firms in general. In Hungary, firms have to send a monthly report about their business transactions with other companies and the related VAT to the National Tax and Customs Administration. We use this large-scale dataset on VAT records from Hungary to map the nation-wide business transaction network of firms. Combining further financial and geographic data from company registers to the network allows us to analyse business ties at different scales of industrial and spatial aggregation. This makes Hungary an exceptional testing ground for economic theories and a unique case for developing data-driven local economic development policy recommendations.
Industry clusters, the spatial concentration of industries in regions, are at the center of the project. Clusters foster higher innovation and economic performance of firms and they are key for local economic development. Researchers in economic geography and related fields have been studying the factors behind the success of clusters for decades and they stress the role of three different mechanisms: knowledge spillovers, labor market pooling and input-output linkages.
The project aims to enhance the understanding of industry clusters from both scientific and policy perspectives. By aggregating firm-level business transactions, we create industry-region level connections, enabling us to map business relationships between key industries within and across regions. In addition to illustrating these industry-region linkages, we construct a labor flow network using an employer-employee matched dataset to capture labor market dynamics and knowledge transfer across sectors.
The first objective of the project is to build an online, interactive data visualization platform that represent the inter-regional connections of industries in Hungary. This site could provide up-to-date information to policy-makers about the existing capabilities of regional economies, supporting the development of place-based Smart Specialization Strategies.
Beyond agglomeration economies, the success of industry clusters is argued to be due to the cooperation of local firms, related industries and supporting institutions. Network analytical tools are widely used to map collaborative learning and the flow of information and knowledge between organizations in clusters. The second objective of the project is to provide systematic evidence on the connection patterns of firms in successful industry clusters through VAT records and labor flow networks.
The project strives to combine theories, approaches and tools from a diverse set of scientific fields, such as economics, network science, geography and computer science. Moreover, it proposes to use a uniquely detailed dataset beyond academic research and aims to develop tools that can inform policy makers about economic connections.
