This article presents site selection for special economic zone (SEZ) development at Nong Khai Province, and appropriate industrial type for the selected suitable SEZ site. The study steps consisted of spatial planning for site selection and industrial type by strategic environmental assessment (SEA).  Spatial planning was started with 11 SEZ potential sites previously declared by Nong Kai Province. Then, 11 potential SEZ sites were screened out by excluding  the area where have already been designated for other uses, including commercial area, tourism area, and industrial area; and with the criteria of industrial estate; 11 SEZ potential sites was cut down to 7 and 3 SEZ potential sites, respectively.   Finally, overlaying of 3 SEZ potential sites on town planning map, only one SEZ site was classified as suitable SEZ site. It is Animal Raising Public area, Chai Ya Village, no 4, Sra Kai Sub-district,
Sra Kai District, Nong Kai Province, covering total area of 718 rai or 115 hectares. Later, SEA was applied to assess the industrial alternatives proposed to such suitable site. Alternatives included no development of industrial (no action), all types of industries permission, only eco-industrial type permission. Impact assessment was performed through 3 implys; check list multi-criteria analysis indicators, impact matrices analysis for assessing impact score of alternatives. The maximum assessed impact score was calculated. With the maximum assessed impact score, eco industry was proposed to such defined suitable SEZ site
