本文考察了经济开发区对中国现有企业生产率的影响。要处理的选择问题，我首先考虑到潜在的不同的选择机制，在两种流行类型的经济技术开发区（ETDZs）和高新技术开发区（HTDZs）的经济技术开发区-依靠多个治疗倾向分数匹配技术。接下来，我将差异中的差异估计应用于匹配样本，并进行事件研究分析。研究结果表明，经济技术开发区和高新技术开发区对企业生产率的影响都是正的，但随着时间的推移呈现出非线性的趋势。然而，生产率提高的幅度在很大程度上取决于经济开发区的类型。一个新的高新技术开发区（ETDZ）导致现有企业在该区成立后的5年内平均生产率提高高达30.2%（18.4%）。这些研究结果表明，生产率溢出效应的大小空间目标企业的差异相当显着取决于战略发展和政策目标的经济开发区：HTDZs，侧重于促进土著学习因素导致更高的生产率溢出效应相比，经济开发区，侧重于促进本地以外的联系。
This paper examines the impact of economic and development zones (EDZs) on the productivity of incumbent firms in China. To deal with the selection issue, I first take into account potentially different selection mechanisms across two popular types of EDZs-economic and technological development zones (ETDZs) and high-tech development zones (HTDZs)-by relying on multiple treatment propensity scores matching techniques. Next, I apply the difference-in-differences estimator to the matched sample and conduct an event study analysis. The results show that the respective effects of ETDZs and HTDZs on firm productivity are positive, but subject to a nonlinear trend over time. The size of the productivity gains depends critically on the type of EDZ, however. A new HTDZ (ETDZ) leads to an average productivity gain of up to 30.2% (18.4%) for incumbent firms in the 5 years after the zone was created. These findings suggest that the size of productivity spillovers for spatially targeted firms differ quite significantly depending on the strategic development and policy goals of the EDZ: HTDZs that focus on promoting indigenous-based factors of learning lead to higher productivity spillovers compared with ETDZs that focus on promoting extra-local linkages.
