强镇改革实践已逾二十年,其总体效果如何,各地差异如何,有哪些类型?基于政府权能理论,可从镇级政府权力和能力两个维度构建强镇改革绩效的四种类型:耦合能效型、融合求变型、失衡变通型和失衡负能型。结合多案例比较分析发现:耦合能效型和融合求变型绩效较为明显,而失衡变通型和失衡负能型绩效亟待提升。其中,耦合能效型下,镇级政府权能作用发挥最佳,失衡负能型因超负荷运转导致镇级政府权能难以发挥甚至起负面作用。四种绩效类型表现出不同特征、效益、策略与向度,彼此之间可能出现积极或消极转化。为此,深化强镇改革,应分类处理好镇级政府权能结构关系,推进权能动态耦合,助力镇级治理效能提升和地方治理绩效优化。

Four decades of full-scale nitrous oxide emission inventory in China

China is among the top nitrous oxide（N2O）-emitting countries, but existing national inventories do not provide full-scale emissions including both natural and anthropogenic sources. We conducted a four-decade（1980–2020） of comprehensive quantification of Chinese N2O inventory using empirical emission factor method for anthropogenic sources and two up-to-date process-based models for natural sources. Total N2O emissions peaked at 2287.4（1774.8–2799.9） Gg N2O yr-1in 2018, and agriculture-developed regions, like the East, Northeast, and Central, were the top N2O-emitting regions. Agricultural N2O emissions have started to decrease after 2016 due to the decline of nitrogen fertilization applications, while, industrial and energetic sources have been dramatically increasing after 2005. N2O emissions from agriculture, industry,energy, and waste represented 49.3%, 26.4%, 17.5%, and 6.7% of the anthropogenic emissions in 2020,respectively, which revealed that it is imperative to prioritize N2O emission mitigation in agriculture,industry, and energy. Natural N2O sources, dominated by forests, have been steadily growing from 317.3（290.3–344.1） Gg N2O yr-1in 1980 to 376.2（335.5–407.2） Gg N2O yr-1in 2020. Our study produces a Full-scale Annual N2O dataset in China（FAN2020）, providing emergent counting to refine the current national N2O inventories.
