Abstract

The Cheollian Satellite 2A called Geo-Kompsat-2A is a geostationary meteorological satellite operated by Korea Meteorological Administration for weather and space-weather observation purposes. This article seeks to evaluate the public value arising from improving the accuracy of early detection of cumulonimbus using Geo-Kompsat-2A. To this end, an economic technique called contingent valuation (CV) is adopted taking a three step approach. In step 1, a CV questionnaire was prepared for deriving the willingness to pay (WTP) for the improvement. In step 2, a nationwide survey of 1000 households was conducted using the CV questionnaire and employing person-to-person interviews with household visits. In step 3, the average WTP was estimated. The yearly household average WTP was KRW 2143 (USD 1.91), securing statistical significance. Adjusting this value to suit the entire population of South Korea produces a yearly public value of KRW 44.1 billion (USD 39.3 million). Although it is not easy to accurately evaluate the costs involved in the improvement, the results of conducting a pilot cost-benefit analysis suggest that the improvement secures social desirability.

评价利用韩国静止卫星提高积雨云早期探测精度的公共价值

“铁莲2A卫星”(Geo-Kompsat-2A)是韩国气象厅为观测天气和空间天气而运营的地球同步气象卫星。本文旨在评估利用Geo-Kompsat-2A提高积雨云早期检测精度所产生的公共价值。为此，采用了一种称为条件估值(CV)的经济技术，采用三步法。在步骤1中，准备了一份CV问卷，以获得改进的支付意愿(WTP)。第二步，在全国范围内对1000户家庭进行调查，采用简历问卷和家访的面对面访谈。在步骤3中，估计平均WTP。家庭年平均WTP为2143韩元(1.91美元)，具有统计学意义。调整这个数值以适应整个韩国人口，每年产生的公共价值为441亿韩元(3930万美元)。虽然不容易准确地评估改善所涉及的成本，但进行试点成本效益分析的结果表明，改善确保了社会的可取性。

期刊介绍： Space Policy is an international, interdisciplinary journal which draws on the fields of international relations, economics, history, aerospace studies, security studies, development studies, political science and ethics to provide discussion and analysis of space activities in their political, economic, industrial, legal, cultural and social contexts. Alongside full-length papers, which are subject to a double-blind peer review system, the journal publishes opinion pieces, case studies and short reports and, in so doing, it aims to provide a forum for the exchange of ideas and opinions and a means by which authors can alert policy makers and international organizations to their views. Space Policy is also a journal of record, reproducing, in whole or part, official documents such as treaties, space agency plans or government reports relevant to the space community. Views expressed in the journal are not necessarily those of the editors or members of the editorial board.
