This article consolidates the pros and cons of the two common modelling techniques for economic impact analysis: the input–output multiplier and the computable general equilibrium (CGE) technique. The latter is recommended for large event assessment and was used to examine the economic impacts of the Gold Coast 2018 Commonwealth Games. The Games is estimated to have generated approximately A$2.5 billion of gross state product (GSP) to Queensland after netting out the costs incurred. The effect is spread over a period of nine years from pre-Games period of preparation for the Games, through the Games period itself, and then rather significantly in the post-Games period. While benefits accrue to Queensland, the rest of Australia is estimated to lose due to the so-called ‘crowding out effect’.

模拟大型赛事的经济影响：以 2018 年黄金海岸英联邦运动会为例

本文综合了经济影响分析的两种常用建模技术的优缺点：投入产出乘数和可计算一般均衡 (CGE) 技术。后者被推荐用于大型赛事评估，并用于检查 2018 年黄金海岸英联邦运动会的经济影响。在扣除产生的成本后，估计奥运会为昆士兰州创造了大约 25 亿澳元的州生产总值 (GSP)。从赛前备战阶段，到奥运会本身，再到赛后阶段，这种影响持续了 9 年的时间。虽然昆士兰州会受益，但由于所谓的“挤出效应”，澳大利亚其他地区估计会受到损失。
