【摘要】：对美国、加拿大、澳大利亚、新西兰、英国、荷兰等国的地理信息经济效益定量估算内容、方法和结果进行了研究和综述。当前,国际发达国家主要对空间信息基础设施、地理信息产业产值和地理信息的经济影响进行了估算,主要综合采用了自下而上、按比例放大、条件价值评估和一般均衡模型法等方法。从研究结果看,虽然目前地理信息产业产值占各国的GDP比例不到1%,但是,其经济影响在有的国家已超过20倍。本文在研究国际有关情况的基础上,提出了开展我国地理信息经济效益定量估算的有关建议。
[Abstract]:The contents, methods and results of quantitative estimation of geographical information and economic benefits in the United States, Canada, Australia, New Zealand, the United Kingdom and the Netherlands are studied and reviewed. At present, the international developed countries have mainly estimated the spatial information infrastructure, the output value of the geographical information industry and the economic impact of geographical information, mainly using bottom-up, proportional amplification. Conditional value evaluation and general equilibrium model method. According to the results of the study, although the output value of geographic information industry accounts for less than 1% of GDP in various countries, its economic impact has exceeded 20 times in some countries. On the basis of studying the international situation, this paper puts forward some suggestions for quantitative estimation of geographical information economic benefits in China.
