There is mutual contradiction between direction estimation of user's signal and power allocation among all users in the beamforming algorithm. A twice game beamforming algorithm based on game theory is proposed to deal with it. Beamforming game algorithm mathematics model is constructed. During the first game, direction of signal and power allocation are mapped the game theory as "player", which are modeled as the problem of maximin function and obtain direction estimation first. Then during the second game, power allocations of different users are described as a multi-user game. Power updated algorithm is designed. The existence and uniqueness of the Nash equilibrium in the twice game beamforming algorithm based on game theory are proved by mathematics derivation.

本文考量政府预算限制下，探讨最适碳税税率与补贴率订定之问题，获得如下发现：(1)发电量补贴与资本补贴对促进再生能源发展效果不一样，决定於再生能源资本的生产力，如果资本生产力足够高，则发电量补贴效果较佳；反之，则应优先采行资本补贴措施；(2)发电量补贴与资本补贴的确存在抵换而非独立关系，亦即在政府预算限制下，为促进再生能源发展，应将种种补贴措施整合考量，以最低行政成本达到再生能源发展目标；(3)再生能源管制配比与碳税税率及资本补贴率呈反向变化关系；而与发电量补贴呈正向关系；(4)绿色权证交易制度具促进再生能源管制目标达到之奖励效果，因此，绿色权证价格提高可降低发电量补贴及碳税税率，降低碳税对经济不利冲击效果；(5)政府如果采行较宽松环境目标，宜提高碳税税率，避免环境品质进一步恶化，然而，对发电量或资本补贴之影响效果不确定；(6)再生能源发电效率愈高，则应提高再生能源发电补贴，在预算限制下，应降低再生能源资本补贴；(7)透过台湾三座风力机组的实证分析，采取差异性发电量补贴，将可诱导较高效率风力机组的投资行为，提高整体风力发电效率，达到再生能源发展之目标。
