This study aims to analyze the existence of beta absolute convergence and beta conditional convergence, the impact of fiscal decentralization in terms of income and expenditure side on per capita income and the process of accelerating the per capita income convergence using 2015-2019 panel data of 113 regencies/municipalities obtained from Central Bureau of Statistics and the Directorate General for Fiscal Balance. Using fixed effect regression models, this study confirms that there are beta absolute convergence and beta conditional convergence in Java Island during 2015-2019. Other findings are Local Own Source Revenue and Fiscal Balance Fund have a significant positive effect on per capita income growth, while Personnel Expenditure and Capital Expenditure have a significant negative effect on per capita income growth. The results also show that all indicators of fiscal decentralization play significant role in accelerating the convergence of per capita income. Based on the results of estimates, Local Government Own Source Revenue should be optimized and quality of government spending have to be improved to foster income per capita convergence between regions in Java Island. Keywords: income per capita convergence, fiscal decentralization regional inequality, absolute beta convergence, conditional beta convergence

This research provides empirical evidence of the effect of fiscal decentralization on poverty alleviation and used data from 505 districts/cities in Indonesia from 2010 to 2019. The poverty rate is used as an indicator to measure the social condition of the area with the parameter of the percentage of the total population below the poverty line, while the fiscal decentralization indicator uses approach to the size of the ratio of PAD to total regional income and expenditure. The estimated results used the fixed effect model shows that fiscal decentralization have significant role to reduce the level of poverty in districts/cities nationally. From this estimation result, the recommended policy formulation is pro-poor fiscal decentralization through strengthening regional financial capacity, both optimizing Original Local Government Revenue (PAD), allocating Transfer Funds to Regions that are specific grants, improving the quality of spending and regional financial management, as well as mechanisms monitoring - better evaluation. In addition, the effectiveness and efficiency of regional government policies in dealing with socio-economic issues such as unemployment and growth population must also be considered.
