| 總結: | This study traces the effect of water supply on output, employment and labor income in the Mexican state of Nuevo Leon. For this purpose, an input-output model with emphasis on the water sector is constructed. Firstly, water is isolated from electricity and gas as these utilities are recorded as a single sector. Secondly, water is disaggregated into four categories: drinking water, aquifers, sewage and treated wastewater. The results suggest that the water sector, particularly the provision of drinking water, has significant knock-on effects on the rest of the economy, which currently are sub estimated due to the lack of disaggregation.
