In the context of the global shift toward sustainable development, ecosystem-based ecological industries have become a critical area of focus for achieving green economic transformation and promoting the harmonious development of both society and the environment. This paper aims to explore the impact of industrial integration on the progression of ecological production within the framework of digitalization, with a particular emphasis on key sectors such as agriculture, forestry, and tourism. Utilizing multi-group data from 284 cities spanning the period 2011 to 2020, the study establishes a relationship between industrial integration and the growth of ecological industries, employing a two-way fixed effects model for analysis. The results demonstrate that industrial integration within ecological sectors significantly fosters sectoral development through two main mechanisms: the extension of industrial value chains and cross-sectoral synergies. Moreover, in the era of the digital economy, digitalization plays a pivotal role in facilitating the integrated development of ecological industries. The study further identifies that digital technology, digital finance, and digital expertise serve as mediating factors in this integration process. It is recommended that future initiatives focus on leveraging digital tools to enhance the integration of ecological industries, thereby advancing industrial growth. Furthermore, China is encouraged to continue promoting the integrated development of ecological industries by supporting the expansion of industrial value chains and fostering intersectoral cooperation. Simultaneously, the role of digitalization should be emphasized, with particular attention to the incorporation of relevant digital components into the industrial integration process moving forward.

Chinese 碳排放与经济增长二者关系协调对积极稳妥推进碳达峰碳中和具有重大意义。以浙江与安徽为对比案例，从环境库茨涅兹曲线理论出发，基于脱钩模型和因素分解法，分析1997—2020年省域碳排放与经济增长的EKC曲线、脱钩态势及驱动因素。研究表明，浙江、安徽两省碳排放与经济增长EKC不符合传统倒“U”型曲线，均经历两次拐点，浙江为“N”型EKC，拐点年约为2007年和2014年，对应人均GDP为36 766元和73 388元，安徽省为微弱的倒“N”型EKC曲线，拐点年约为1998年和2013年，人均GDP为4 452元和32 733元；浙江碳排放脱钩由扩张负脱钩向强脱钩与弱脱钩方向转变，安徽以弱脱钩状态为主；能源结构与强度效应对浙江省的碳排放脱钩促进作用明显，而经济增长与能源结构效应对安徽省碳排放脱钩起负向作用。 English The coordination between carbon emissions and economic growth is of great significance to actively and steadily promote carbon peak and carbon neutrality. Taking Zhejiang and Anhui as a comparative case, starting from the theory of environmental Kuznets curve, based on the decoupling model and factor decomposition method, this paper analyzes the EKC curve, decoupling trend and driving factors of provincial carbon emissions and economic growth from 1997 to 2020. The results show that the carbon emission and economic growth EKC of Zhejiang and Anhui provinces do not conform to the traditional inverted U-shaped curve, and both experience two inflection points: Zhejiang has a positive N-shaped EKC, the inflection point years are about 2007 and 2014, and the corresponding per capita GDP is 36 766 yuan and 73 388 yuan, and Anhui Province has a weak inverted N-shaped EKC curve, the inflection point years are about 1998 and 2013, and the per capita GDP is 4 452 yuan and 32 733 yuan. Zhejiang's carbon emission decoupling has changed from expanding negative decoupling to strong decoupling and weak decoupling, and Anhui is dominated by weak decoupling. The effect of energy structure and intensity has a significant effect on the decoupling of carbon emissions in Zhejiang Province, while the effect of economic growth and energy structure has a negative effect on the decoupling of carbon emissions in Anhui Province.

This study investigated the convergence trend and driving effect of carbon deocupling in APEC during 1990-2019.

Supercritical water oxidation (SCWO) technology is efficient and offers significant development potential for hazardous waste treatment. The use of water in a supercritical state with special physical and chemical properties for refractory organic matter processing offers significant advantages. This article summarizes (i) the mechanism of SCWO technology and its research progress for oily sludge treatment; (ii) the effects of reaction temperature, pressure, residence time, oxygen ratio, catalyst, antioxidant, and other factors on oily sludge treatment; and (iii) problems in the current process. Finally, SCWO technology for the future development of oily sludge treatment is discussed.
