The achievement of sustainable energy systems requires well-designed energy policies, particularly targeted strategies to plan the direction of energy development, regulations monitored and executed through credible authorities and laws enforced by the judicial system for the enhancement of actions and national targets. The Asia–Pacific region (APAC), responsible for more than half of global energy consumption, has enacted a large number of energy policies over the past two decades, but progress on the energy transition remains slow. This study focuses on the aggregate effect of energy policies on the progress towards sustainable targets in 42 emerging economies from 2000 to 2017. We find that energy policies have contributed to improving access to electricity (3.0%), access to clean cooking (3.8%), energy efficiency (1.4%) and renewable electricity capacity (6.9%), respectively. Among different types of energy policy (strategies, laws and regulations), strategies have greater impacts on advancing electrification, clean cooking and renewable electricity capacity than laws and regulations, whereas the laws are more effective for achieving energy efficiency.

可持续能源系统的实现需要精心设计的能源政策，尤其是规划能源发展方向的有针对性的战略、通过可信当局监督和执行的法规以及司法系统执行的法律，以加强行动和国家目标。占全球能源消费一半以上的亚太地区（APAC）在过去二十年制定了大量能源政策，但能源转型进展仍然缓慢。本研究重点关注 2000 年至 2017 年期间 42 个新兴经济体实现可持续目标进展的能源政策的总体影响。我们发现，能源政策有助于改善电力供应（3.0%）、清洁烹饪供应（3.8%） , 能源效率 (1. 4%）和可再生电力容量（6.9%）。在不同类型的能源政策（战略、法律和法规）中，战略对推进电气化、清洁烹饪和可再生电力产能的影响大于法律法规，而法律对实现能源效率的影响更大。
