- Abstract
Building high voltage overhead transmission lines (HVOTL)may incur huge external social cost. This study attempts to estimate such external cost using the Taipower Company's Nantou-Changlin HVOTL as a case study. This HVOTL likely affects the values of farmland. Data were collected from a field survey de- signed from the contingent valuation method (CVM). An econometric model using farmland price as the dependent variable was specified and estimated by two-stage least squares (2SLS) and Heckman two-step model (Heckit). The econometric results show that building this HVOTL would reduce the value of farmland within 600 meters from this line with 23.6 km on both sides. The closer to HVOTL, the lower is the farmland price. The total lost farmland value amounts to 17.1 billion NT dollars. This amount is more than six times the construction cost of 2.7 billion. These research results should be very useful to the Taipower Company and government agencies in assessing the external social cost of the construction of HVOTLs in Taiwan.
