Data for "Regional Economic Ripple Effects of Paddy-Field Agrivoltaic Systems: An Input–Output Analysis Based on a Model Case in Yamagata Prefecture"

This dataset accompanies the research article entitled "Regional Economic Ripple Effects of Paddy-Field Agrivoltaic Systems: An Input–Output Analysis Based on a Model Case in Yamagata Prefecture" by Minami Ishida, Yoshiki Kuwabara, and Masahide Hayashi. The dataset provides the assumptions, input data, calculation procedures, and results of a regional input–output analysis assessing the economic impacts of agrivoltaic systems combining rice cultivation and solar photovoltaic electricity generation in Yamagata Prefecture, Japan. The analysis uses the 2020 Yamagata Prefecture input–output table (108 sectors) and a model agrivoltaic facility. It examines two stages: Operation stage: Changes in regional production and gross value added relative to conventional rice cultivation without photovoltaic generation, including sensitivity analyses for agricultural production, electricity selling prices, and electricity import substitution. Investment stage: Regional economic impacts of facility investment under baseline and increased local procurement scenarios. The dataset consists of an Excel workbook containing the analytical assumptions, input–output coefficients, sectoral calculations, scenario results, and supporting data sources, together with a README describing the methodology and interpretation. Access to the files is restricted because the workbook includes business-related cost information provided by a facility operator. Access may be granted upon request for academic research and verification purposes, subject to review of the intended use and applicable data-use conditions. Redistribution or public disclosure of restricted information is not permitted without the necessary authorization.
