The impact of investments in special economic zones on regional development: the case of Poland
研究波兰经济特区的投资激励对区域发展的实际效果，采用反事实评估方法分析企业投资、公司数量和失业率等指标，发现特区对最不发达地区有强正面影响，对较富裕地区效果弱或负面。
Special economic zones (SEZs) in Poland were established explicitly to enhance regional development, crafting a series of investment incentives designed to boost investment attractiveness in particular regions. How have these incentives fared in reality? To capture the impact of SEZs upon regional development in the country, we use a counterfactual evaluation method across a number of important metrics, including company investment, number of companies and unemployment. The analysis shows that SEZs have had a strongly positive impact upon the development of the least-developed regions in Poland, while in relatively richer ones the effect was weak or even negative.
