The document discusses special economic zones (SEZs) or ecozones in the Philippines. It defines ecozones as selected areas developed for agro-industrial, industrial, tourist or other business purposes. Ecozones can include industrial estates, export processing zones, and free trade zones. The Philippine Economic Zone Authority (PEZA) was established to manage ecozones and grant incentives to developers. However, tensions exist between ecozone autonomy and local autonomy regarding legal status, smuggling prevention, security, local government power, and tax exemptions. The document concludes the ecozone law needs revising to better define relationships between national, local and ecozone governance.
