当前城市化的趋势伴随着农村地区人口和经济的日益萎缩。在日本等国家，根据GDP（用于指导政府政策的传统衡量标准），这些农村地区落后于大城市地区。然而，过去的研究表明这些地区的价值可能被低估。此外，包容性财富指数（IWI）主要只在国家层面使用，也许能够捕捉到以前遗漏的方面。因此，我们的研究试图通过比较1990年至2014年佐渡岛和日本的普惠性财富来突出农村地区的财富。根据当地数据的可用性，对方法进行了细微的修改，以提高人力资本估算的准确性。结果反映了佐渡岛的持续萎缩，并证明了 IWI 作为库存指标的独特潜力。佐渡的人均财富比全国平均水平低约10%，但其自然资本约为全国平均水平的三倍。对渔业和人工林自然资本的补充估计表明，在评估中纳入额外因素将进一步提高农村地区的相对价值。我们讨论了我们对福祉的估计的影响，并以对 IWI 计算对指数政策实施的批判性评估作为结论。
Present trends of urbanization are accompanied by increasing demographic and economic shrinkage of rural regions. In countries such as Japan, these rural regions trail behind metropolitan counterparts according to GDP, the conventional measure used to guide governmental policies. Yet, past research suggests that these regions may be undervalued. Further, the Inclusive Wealth Index (IWI), largely only used at the national level, may be able to capture aspects previously missed. As such, our study attempts to highlight the wealth of rural regions by comparing the inclusive wealth of Sado Island and Japan between 1990 and 2014. Minor methodological modifications were made according to data availability at the local level and to improve the accuracy of human capital estimations. Results captured the ongoing shrinkage of Sado and demonstrate the distinct potential of the IWI as a stock measure. Sado’s per capita wealth was about 10% lower than the national averages, but its natural capital was about threefold national averages. Supplementary estimations of the natural capital of fisheries and cultivated forests suggest that inclusion of additional factors in the evaluation would further increase the relative valuation of rural regions. We discuss implications of our estimations for wellbeing, and conclude with a critical appraisal of the IWI calculation towards policy implementation of the index.
