Analysis and evaluation of structural complexity of circular economy system＇s industrial chain

This paper examined the method to evaluate structural complexity of circular economy system＇s industrial chain, which applied entropy information and hierarchical metrics to produce complexity degrees according to the theory of complex system. We developed an evaluation model to make a general metrics for circular economy system of industrial chains. The development of the evaluation tree drew upon five factors to identify the structural complexity. The evaluation model generated unitive entropy information from six data definition （node, level of community, metabolic span, degree of node, number of relation and connectivity of node） according to the evaluation tree. The industrial chains of Tashan circular economy park of Datong Coal Mine Group and Gujiao circular economy park of Xishan Coal-Electricity Group were evaluated by the proposed method. The key factors stunted by the decline of structural complexity were identified and the unitive metrics of entropy information of the industrial chain was shown for realigning the circular economy systems.

The Rice Processing Industry in Nepal: Constraints and Opportunities

A rice mill survey covering diverse rice processing companies in terms of their milling output, type of technology and year of establishment was conducted to understand the current situation of the rice milling industry and to identify enablers and barriers to its growth in Nepal. Coarse rice varieties dominate Nepal’s rice processing industry, with a 42% share by total weight, followed by medium rice (34%) and fine varieties (less than 7%). Polished white rice (Arwa) was the dominant rice type in Nepal in the survey, followed by parboiled and steamed rice. The price and profit margins increased from coarse to fine rice varieties and from Arwa to parboiled and steamed rice. The cost of milling also followed a similar trend. The rice milling industry in Nepal largely influences the adoption or non-adoption of any specific type of rice variety by dictating specific brands in the market and this has important implications for rice research and development. The rice processing industry of Nepal was unable to compete with the Indian rice milling industry because of: 1) low profit margins due to the high cost of rice production and procurement, 2) a lack of economies of scale, 3) a lack of milling technologies for long and extra-long and steamed rice in the country and a lack of investment to modernize rice milling technology, and 4) unavailability of paddy throughout the year locally. Millers were willing to upgrade their rice milling technology to include high throughput parboiling, steamed rice as well as long and extra-long grain rice. This will be a strategic decision in counteracting the ever-increasing rice imports in Nepal. We believe that the findings of the study will be vital for formulating an appropriate rice research, development and rice processing strategy for Nepal to achieve food and nutritional security and the Sustainable Development Goals.

Exploring the coupling relationship of industrial agglomeration and low-carbon economy considering spatiotemporal differentiation:An empirical study in China’s construction machinery industry

Although China’s construction machinery thrives to meet the needs of construction,a number of challenges still remain to be overcome,such as lack of thorough knowledge of regional disparities and several limitations in terms of carbon emissions and economic development.Meanwhile,a low-carbon economy was proposed and implemented in China.This research aims to investigate the differences in industrial agglomeration of construction machineries and further explore the relationship between industrial agglomeration and low-carbon economy.On this basis,spatiotemporal analysis was performed to evaluate the levels of industrial agglomeration in different regions based on the situations of China’s construction machinery industry.Furthermore,this study explored the interaction between industrial agglomeration and low-carbon economy utilizing the coupling coordination analysis method.Results showed that the coupling coordination of the two subsystems was extremely unbalanced in 2006,and it maintained an increasing trend,reaching a relatively high level in 2018.Finally,suggestions,such as establishing a policy guarantee system and implementing variable policies in different regions,were proposed to provide guidelines for the government decision-making and promote the sustainable development of China’s construction machinery industry.

Thoughts and Prospects for Promoting Energy-Saving and Carbon Footprint Reduction in the Non-Ferrous Metal Industry

As the upstream of high-energy consumption industries such as metallurgy and chemical enterprises, the “carbon neutrality” ability of mining and mining enterprises can have a strong influence on the progress of China’s non-ferrous metal industry to achieve the “double carbon” goal. According to the Global Mining Development Report 2021, although mining occupies an important position in global economic development, it also accounts for 4% to 7% of global greenhouse gas emissions. Therefore, as an important part of promoting China’s economic development and energy structure transformation, mining will also face scale adjustment. By investigating and studying the carbon emission sources of mining enterprises at the current stage at home and abroad, the carbon neutrality method that has been implemented in mines, and the future low-carbon technologies to be developed, this paper provides the thoughts and prospects for promoting the development of green mines, as well as the reference value for the transformation of China’s mining industry.

东盟国家新能源汽车产业发展的政策措施与路径

新能源汽车作为交通运输领域发展“绿色化”的重要解决方案之一,在东亚、北美及欧洲等多个国家及地区得到大力发展。其中,东盟国家为实现节能减排、满足市场环保需求、弥补汽车产业链短板等目的,有计划地推进新能源汽车产业建设。其主要举措包括:推行双向政策目标,构筑产业方向蓝图;调节供需税收水平,激活产销潜在势能;建设基础设施网络,打造使用生态场景;加大投资政策倾斜,扶持本土产业转型等。在通过“差异化”引资优惠政策实现外资与本土合作转化的基础上,充分发挥自身资源禀赋优势发展电池核心产业,积极鼓励产业链多环节共同发展,东盟国家已初步搭建起新能源汽车产业框架,产业链建设取得一定成效。但由于起步较晚,政策反馈滞后,东盟国家新能源汽车产业发展进程受到一些制约;加上工业基础薄弱与创新资源匮乏,使其难以摆脱“低端锁定”困境;补贴退坡后,消费惯性与产品认知模糊也给当地新能源汽车可持续发展带来巨大挑战。因此,在已有政策基础上,东盟国家可参考他国成功经验,充分发挥自身比较优势吸引区域内投资,采取一系列有效措施,推动新能源汽车产业规模化发展。

后发经济体在全球产业链重构中的弯道超车——历史经验及对中国的启示

全球产业链重构为后发经济体提供了弯道超车的机会,有利于其充分发挥自身的后发优势,实现本土产业链的长足发展。纵观全球产业链发展史,颠覆性的技术创新、比较优势变化和全球治理体系变革是驱动全球产业链重构的主要机制。到目前为止,全球产业链共经历了五次重构,依次伴随着美国、日本、“亚洲四小龙”、中国以及南亚和东南亚地区等相应时期后发经济体的崛起。通过研究驱动机制和后发经济体案例,本文发现后发经济体在参与全球产业链重构时,需重点关注核心技术、需求市场以及国际经贸规则等方面,从而充分发挥后发优势,实现弯道超车。基于此,中国应借鉴后发经济体在全球产业链重构中的弯道超车经验,抓住目前全球产业链重构的新发展机遇,不断推动技术进步以促进产业链升级,不断扩大内需以保障产业链安全,还应积极参与全球治理规则重构,为全球治理体系变革贡献中国方案。
