Abstract:The strategic allocation and use of policy tools in international energy cooperation are essential for achieving policy objectives. At the same time, policy actors play crucial roles in formulating, implementing, and evaluating these policies. In China’s international energy cooperation, there is a notable interdependence between the policy tools and the actors involved. This study first constructs a two-dimensional analytical framework—combining policy tools and policy actors—classifying existing policies related to energy international cooperation into three categories: supply side, environmental, and demand side, based on the framework proposed by Rothwell and Zegveld. It then analyzes the frequency and patterns of policy documents published by individual and joint actors over the years. Finally, the study maps the cooperation networks of joint publication actors within each policy category and examines their characteristics, particularly focusing on those actors with significant intermediary and influence roles . The findings are as follows: (1) Among the three policy types, supply side tools are the most frequently used, but their cooperation networks exhibit the most structural holes and suffer from lower efficiency. (2) The National Development and Reform Commission (NDRC) and the Ministry of Science and Technology (MOST) consistently occupy key intermediary positions and exert significant influence across all three networks, while the National Energy Administration (NEA) exerts weaker influence and plays a less prominent intermediary role in the supply side network compared to its roles in the environmental and demand side networks. (3) In the supply side network, key actors such as the NDRC, MOST, and Ministry of Finance are critical to addressing structural gaps and improving network efficiency. These actors can enhance the use of low-frequency tools or collaborate with essential departments like the NEA to fill these gaps. These findings offer novel recommendations for advancing energy international cooperation policies.
