This paper aims to explore various possibilities in the evolving global gas market by constructing game-theoretical models involving the major players: Russia and Qatar exporting gas to the Asia-Pacific and Europe, respectively. We explore a series of hypothetical scenarios based on competitive and collusive settings for the Asia-Pacific LNG market and based on Qatar's export route to the European gas market. The scenarios that are examined are (1) Russia as the follower and Qatar as the leader in a Stackelberg game; (2) Russia and Qatar as Cournot competitors; (3) collaboration between Russia and Qatar as bilateral monopolies; (4) Qatar exporting gas to European borders; (5) Qatar exporting gas to the last transit country; and (6) Qatar transporting gas to the Turkish border under a multi-pricing scheme. Demand is estimated under each scenario to simulate the respective export volumes, prices and quantities, and profit in each scenario. By exploring these market interactions, we find that it is essential for Russia to strike a deal with Qatar in the Asian market and accelerate their gas production in order to compete as an LNG market leader. Russia is likely to benefit more if it can link with Qatar to act as a monopoly on their segmental demand curve. On the other hand, Qatar's profit is expected to be higher under the scenario when Qatar sells all the gas to the last transit country as the sole demand point instead of passing through transit countries.
本文旨在通过构建博弈论模型来探索不断演变的全球天然气市场中的各种可能性,该模型涉及主要参与者:分别向亚太地区和欧洲出口天然气的俄罗斯和卡塔尔。我们基于亚太地区液化天然气市场的竞争与合谋情况以及卡塔尔通往欧洲天然气市场的出口路线,探索了一系列假设情景。所考察的情景包括:(1)在斯塔克尔伯格博弈中俄罗斯作为跟随者,卡塔尔作为领导者;(2)俄罗斯和卡塔尔作为古诺竞争者;(3)俄罗斯和卡塔尔作为双边垄断者进行合作;(4)卡塔尔向欧洲边境出口天然气;(5)卡塔尔向最后一个过境国出口天然气;(6)卡塔尔在多定价方案下将天然气输送到土耳其边境。对每种情景下的需求进行估计,以模拟各自的出口量、价格、数量以及每种情景下的利润。通过探索这些市场互动,我们发现俄罗斯在亚洲市场与卡塔尔达成协议并加速其天然气生产对于作为液化天然气市场领导者进行竞争至关重要。如果俄罗斯能够与卡塔尔联手,在其分段需求曲线上形成垄断,俄罗斯可能会受益更多。另一方面,在卡塔尔将所有天然气作为唯一需求点出售给最后一个过境国而非经过多个过境国的情景下,卡塔尔的利润预计会更高。
