基于北京市人大常委会门户网站,通过收集第十三、十四届北京市人大在立法过程各个阶段的实证数据,分析了北京市人大和政府在立法过程中各自所发挥的作用,从而探究北京市行政-立法关系。研究发现,北京市人大在现实运行中尚未实现其主导功能,具体表现为:“官员”代表和兼职代表比例高、“行政部门化”趋向、程序性手段效用缺失、立法解释权虚置。但是,与此同时实证数据也显示北京市近两届人大正通过调整代表结构、提前介入、强化实质性审议等手段提升立法自主性,推动人大制度与时俱进。 Based on the portal of the Beijing Municipal People’s Congress Standing Committee, by collecting the empirical data of the 13th and the 14th Beijing Municipal People’s Congress in various stages of the legislative process, this paper analyzes the respective roles played by the Beijing Municipal People’s Congress and the government in the legislative process so as to explore Beijing City Administration - Legislation Relations. The study finds that Beijing Municipal People’s Congress has not yet achieved its dominant function in the actual operation. The concrete manifestation is: the high proportion of “officials” representatives and part-time representatives, the tendency of “administrative departments”, the lack of effectiveness of procedural means and the power of legislative interpretation Dummy. However, at the same time, empirical data also show that the last two NPCs in Beijing are upgrading their legislative autonomy by adjusting representative structures, intervening in advance and strengthening substantive deliberations, so as to promote the system of people’s congresses with the times.
