英文文献摘要：
This study assesses the initial economic outcomes of the Delta Regional Authority (DRA), which began funding rural development projects in the Mississippi Delta region in 2002. The study focuses on non-metropolitan DRA counties and similar counties elsewhere in the Mississippi Delta region and the southeast, using a quasi-experimental approach that combines matching methods, double and triple difference and switching regression estimation. We find that per capita income and transfer payments grew more rapidly in DRA counties than similar non-DRA counties, and that these impacts are larger in counties in which DRA spending was larger. Each additional dollar of DRA spending per capita is associated with an increase of $15 in personal income per capita between 2002 and 2007, including an increase of $8 in earnings (primarily in the health care and social services sector) and $5 in transfer payments. The increase in transfer payments is mainly due to increased medical transfer payments. We also find that the number of hospital beds per capita increased more in counties where DRA spending per capita was greater. These findings suggest that investments supported by the DRA in improved medical facilities are promoting additional health sector earnings and medical transfer payments.
这项研究评估了三角洲地区管理局(DRA)最初的经济成果，DRA从2002年开始资助密西西比三角洲地区的农村发展项目。本研究以非大都市的DRA县以及密西西比三角洲地区和东南部其他类似的县为研究对象，采用一种结合了匹配方法、双、三重差分和转换回归估计的准实验方法。我们发现，DRA县的人均收入和转移支付比类似的非DRA县增长更快，而且这些影响在DRA支出较大的县更大。2002年至2007年期间，人均DRA支出每增加1美元，人均个人收入就增加15美元，包括收入增加8美元(主要在卫生保健和社会服务部门)和转移支付增加5美元。转移支付增加的主要原因是医疗转移支付增加。我们还发现，在人均医疗费用支出较大的县，医院的人均病床数量增加更多。这些调查结果表明，DRA对改善医疗设施的投资促进了卫生部门的额外收入和医疗转移支付。
