The effects of special economic zones on employment and investment: a spatial panel modeling perspective
利用波兰379个县2003-2012年的企业级数据，估计面板和空间面板模型，发现经济特区对所在县及邻近县的就业有强正向影响，对投资影响较弱但正向，且不挤出或挤入区外投资。
A set of panel and spatial panel data models of employment and investment is estimated for 379 Polish counties over the 2003–2012 period using unique firm-level dataset for Polish special economic zones (SEZs). SEZs have strong positive impact on employment in the host county as well as in neighboring counties. The effects of SEZs on investment are weaker but nonetheless positive—investment in a given SEZ neither crowds out nor crowds in investments outside the SEZ. These findings are robust to changes in the estimation methods, the sample composition, the set of explanatory variables and the selection of a spatial weight matrix.
