摘　　要：将政府竞争政策与技术创新因素引入到两级多晶硅供应链博弈模型中,研究不同情形下政府竞争奖励与技术创新努力水平对于各级制造商最优利润的影响。构建关于硅片批发价与光伏系统销售量的利润博弈模型,求得了各级制造商的最优利润函数,并通过实证研究分析了竞争与协调两种情形下竞争政策与技术创新因素对于各级制造商最优与整体供应链总利润的影响。研究表明:(1)政府竞争政策有利于增加制造商的利润;(2)技术创新努力水平的升高可以较快的增加制造商的利润;(3)与竞争情形相比,协调情形下各制造商的利润及整个供应链总利润更高。Energy is an important foundation of national economic and social development. How to realize green and sustainable development of energy is a hot topic in the world. China’s demand for high-purity silicon wafers mainly relies on imports, and the photovoltaic systems manufactured are mostly exported due to the impact of domestic environment. However, the high import price and low export price make China become a processor with low added value of photovoltaic system. At the same time, due to the impact of the “531” new policy on China’s photovoltaic industry, the competition among domestic photovoltaic manufacturers is more fierce. It has seriously restricted the healthy development of photovoltaic industry in China. Therefore, on the basis of relevant research, the government competition policy and technological innovation variables are introduced into the model. Different from the previous research, the government competition award is introduced as the interpretation of the government competition policy, and the level of technological innovation effort is introduced as the manufacturer’s efforts to achieve technological innovation. In addition, the Government Competition Award and technological innovation are introduced. The new level of effort is linked to the optimal profit of manufacturers at all levels under different government competition awards and different levels of technological innovation efforts. The two-level model of silicon manufacturer and photovoltaic system manufacturer in polysilicon supply chain is considered a game model about wholesale price of silicon wafer and sales volume of photovoltaic system is established, the optimal profit function of manufacturers at all levels is obtained, and through the 2019 China Photovoltaic Industry Development Research Report, photovoltaic and solar energy industry analysis report and other internal reports related data and forecast data empirical study the impact of competition policy and technological innovation factors on the optimal and overal
