为促进资源合理利用，提高社会公平，自2016年1月起，中国所有供气城市对居民用天然气实行分段加价政策。本文从需求分析的角度探讨了居民用天然气的IBP结构。基于支出收入比（EIR）方法和扩展线性支出系统（ELES），考虑电力替代对居民天然气消费的影响，提出了一种新的EIR-ELES模型，用于估算不同类型居民用户的天然气价格承受能力。本文以北京市为例进行了实证研究。结果表明，2016年居民天然气需求平均价格弹性为-0.4621，无弹性; 2016年居民天然气平均价格承受能力在4.17 ~ 7.48 CNY/m3之间，远高于三个区块的价格，但不同收入水平居民用户的基本需求量远低于第一区块的需求量。基于这些结果，未来的方向和行动的住宅天然气IBP系统的设计和改进的建议。
In order to promote reasonable resource utilization and improve social equity, all cities with gas supply in China has implemented increasing block pricing (IBP) policy for residential natural gas from Jan. 2016. This paper examines the IBP structure of residential natural gas from the perspective of demand analysis. Based on Expenditure-Income Ratio (EIR) method and Extended Linear Expenditure System (ELES), a new EIR-ELES model is proposed to estimate natural gas price affordability of different kinds of residential users by considering the effect of electricity substitute on household natural gas consumption. Taking Beijing as an example, an empirical research is carried out in this paper. The results show that average price elasticity of residential natural gas demand is −0.4621 in 2016, inelastic; residential natural gas average price affordability is between 4.17 and 7.48 CNY/m3 in 2016, which is much higher than the prices in three blocks, but basic volume of demand for residential users with different income levels are much lower than the volume in the first block. Based on these results, future directions and actions for the design and improvement of residential natural gas IBP system are suggested.
