China ‘s steel industry needs to replace the lagging production lines with advanced ones and to pursue group strategic reorganization when facing China ‘s dual-carbon goals.Technical advances and industrial policies indicate that siting new steel production lines is beneficial to production bases, and the site ‘s traffic supports matter. This paper uses DPSIR framework and dynamic comprehensive evaluation model to systematically analyze the logic relation between new sites and their traffic system, and establishes an evaluation system and method for new site ‘s traffic supports. Experimental tests based on China ‘s Baowu Iron & Steel group show that new sites will need to be strongly supported by the local urban traffics to reach the dual caron goals. DPSIR framework of new sites ‘ traffic supports include five levels such as driving forces, pressures, status, impacts and responses, all marking their loop logics between bases and cities ‘ traffic systems inside and over the levels. Evaluation results regarding China Baowu Iron & Steel group during 2015 to 2020 not only verifies the feasibilities of this evaluation system and method, but also approves the practice of DPSIR framework of traffic supports on siting new steel production lines.

Vast quantities of cases show that tourism has become a vital pathway for resource-exhausted cities in their economic transformation, but their correlation needs further study. Effects of tourism in revitalizing the economy of resource-exhausted cities has not been objectively evaluated. This paper uses panel data of China's 24 resource-exhausted cities during 2004 to 2016 to verify if the tourism revitalizes the economy of resource-exhausted cities. Three threshold values in tourism level in energizing their economy are 0.019, 0.026 and 0.031, suggesting the tourism indeed revitalizes the economy, but its marginal contribution rate may decline as tourism develops up to a higher industrial level, so that its push will be exhausted, or even produces new "Dutch disease" that constrains sustainable development of economy. This paper presents suggestions fulfilling its linked effects of tourism industry, pushing tourism industry to promote manufacturing, and boosting a coordinated development of tourism with other industries.

This paper uses DEA and Malmquist index to calculate the total factor productivity of manufacturing industry along “the Belt and Road” from 2006 to 2016, and discusses their regional differences and dynamic rules from temporal and spatial dimensions. Decomposition of total factor productivity is performed to explore the source and drives of its internal changes so as to precisely study the spatial difference and evolution of total factor productivity of manufacturing industry. The total factor productivity of manufacturing industry along “the Belt and Road” shows a U-shaped changing trend which suggests an improved resource allocation efficiency, and is of regional heterogeneity, high in southeastern coast area, followed by northeastern and southwestern area, and then by northwestern area. Technical advances play a key role in increasing the total factor productivity, and research and development input, patent counts, new products revenue and “the Belt and Road” policies are positively related to the total factor productivity.

This paper, according to China's 30 provinces' panel data 2000 to 2016, uses non-expected DEA model to estimate China's whole element energy efficiency, and employs panel data model and media effect model to verify the media effect of technical advances during which financial growth pushes whole element energy efficiency. China's financial development level and energy efficiency generally show a rising trend, varying with regions, much higher in eastern China than in the central and western. Vertically financial growth shows the same changing trend as energy efficiency. Horizontally, the eastern China of highest financial growth level is also of highest whole element energy efficiency. Technical advance imposes a distinguished media effect during financial growth acting on the whole element energy efficiency.

 This paper uses Hebei`s 2010—2015 related data to establish a decoupling model of construction land use expansion and economic growth, which is employed to estimate the decoupling index of the entire province and 138 counties within Hebei province by using ESDA and GIS, discusses its spatial concentrating features and distribution rules, providing references to improve construction land use efficiency. The decoupling index is 0.05-0.97 in the entire province from 2010—2015, implying an expansive decoupling, 0.09-0.70 in the 138 counties also implying an expansive decoupling. The spatial concentrating rule of decoupling between county construction land use expansion and economic growth shows that HH LISA index is mainly spreading in Sanhe, Xianghe and Dachang, and four counties in eastern Xingtai city, LL LISA in nineteen counties in centralsouthern Hebei. The 138 counties are divided into three tiers based on the expansive decoupling types.

This paper establishes an evaluation index system of resources based cities industrial transforming efficiency, uses DEA model to measure industrial transforming efficiency of 19 resources based cities in China’s three northeastern provinces from 2010-2014, aiming at resolving the dilemma in the development of resources based cities, promoting industrial transformation and sustaining the development. The result shows an imbalanced industrial transformation of resources based cities in this area, but with a reducing regional gap. Their industrial transforming efficiency in Fuxin, Liaoyuan, Daqing, Qitaihe and Jilin cities is relatively effective, but Shuangyashan and Benxi are in decreasing payment. Liaoning’s industrial transformation lags behind Heilongjiang and Jilin provinces. Population outflow and insufficient science and technology investment constrain the industrial transformation. This paper presents suggestions for resources based cities industrial transformation and regional economic growth in China’s three northeastern provinces. 

World Metal Statistics and China Custom data show a fast development of China’s manganese sector, with its production and import ranking top in the world. This paper, based on China’s manganese reserve, production, demand, import, import sources, and import prices, presents issues in China’s manganese resource. China lacks high grade manganese ore, out of supply, highlydependence on import. Import sources are concentrated in a few countries, with fluctuated prices and weak overseas resources. This paper presents suggestions on improving technical equipment, investing in rich manganese exploration, increasing its comprehensive use and mining overseas manganese resources.

Evaluation of industrial chain efficacy is based on its efficiency and function.This paper from competitiveness,efficiency,ecologicalstability,sustainability and gross effects reviews the efficacy of industrial chain. The currently-applied evaluation index is generally not systematic and comprehensive,only focuses on its some aspects, also lacks consideration of sample quantity and circumstance.This paper uses SEM to establish a relatively complete and objective evaluation framework DEA mode for industrial chain efficacy,which can effectively eliminate circumstance factor and random errors.

This paper analyzes the exploration situation of Xinjiang’s mineral resources,and concludes that Xinjiang is a vital strategic alternative region for energy,non-ferrous and noble metals with huge potentials.Mining is a key drive to Xinjiang’s economy. Xinjiang’s mineral resources are marked by widely-spreading,abundant categories,developed logistics,large reserves,quality and rational structure of some mineral resources.Limited by its remote sites,poor natural conditions,unde-developed economy,and primitive geological works,lower technology and lack of science talents,Xinjiang’s mineral resources development stays a primary leve land a lower synthetic utilization level.This paper presents approaches to synthetic development and utilization of Xinjiang’s mineral resources.
