摘要：Sustainable development has been the subject of considerable discussion and it has attracted much attention among environmentalist, economist and policy makers. There are few studies of sustainable development measures in Indonesia, but still focused on partial dimension. This study tried to develop index to promote sustainable development assessment in Indonesia, especially at the regional (regency and municipality) level, called Regional Sustainability Index (RSI) using Factor Analysis (FA) with consideration of regional-scale spatial interdependency by employing Local Indicator of Spatial Association (LISA) statistics. There are 416 regencies and 98 municipalities in Indonesia. The data used in this study were secondary data obtained from the Central Statistics Agency (BPS) in 2014. RSI was developed based on 30 regional sustainable development indicators which were divided into 3 major dimensions: economy, social, and environment. Some indicators which develop RSI is covering economic welfare, public services, infrastructure, social welfare, community health and education, physical condition, regional environmental sustainability and disaster resilience. Based on LISA results, it was found that sustainability performance of the regional-scale spatial units (regencies/municipalities) was strongly influenced by the sustainability conditions in its surrounding areas. The approach developed in this study was able to show the actual condition of regional sustainability performance in all dimensions without making it into one composite index so that it could show the index value of each dimension. According to the results, we can conclude that RSI is a very effective method to indicate the locations of the hotspot issues of sustainable development. By this index, we have a new approach for evaluating and reporting economic, social, and environmental conditions at the regional level to support the integration of three dimensions of sustainability. The study concludes that the country has attained high socio-economic sustainability which needs to be addressed. Producing a cluster map of regencies and municipalities by combining the RSI value of each dimension is very helpful for the decision maker to determine the appropriate policy for solving the problems in each region.
