Ecological and Environmental Protection of Jiangxi Province from the Perspective of Low Carbon Economy

With urban economic growth,the urban ecological and environmental pollution is deteriorating. In turn,ecological and environmental pollution restricts urban economic growth. To realize coordinated development of urban economic growth and urban ecological environment,it is recommended to vigorously develop low carbon economy. On the basis of basic situations of ecological and environmental pollution in Jiangxi Province,following the connotation and development principle of the low carbon economy,this paper discussed ideas of ecological and environmental protection in Jiangxi Province,to lay a solid foundation for better promoting social and economic growth.

Fluidized mining and in-situ transformation of deep underground coal resources: a novel approach to ensuring safe, environmentally friendly, low-carbon, and clean utilisation

Traditional coal mining and utilisation patterns are severely detrimental to natural resources and environments and significantly impede safe, low-carbon, clean, and sustainable utilisation of coal resources. Based on the idea of in situ fluidized coal mining that aims to transform solid coal into liquid or gas and transports the fluidized resources to the ground to ensure safe mining and low-carbon and clean utilisation, in this study, we report on a novel in situ unmanned automatic mining method. This includes a flexible, earthworm-like unmanned automatic mining machine (UAMM) and a coal mine layout for in situ fluidized coal mining suitable for the UAMM. The technological and economic advantages and the carbon emission reduction of the UAMM-based in situ fluidized mining in contrast to traditional mining technologies are evaluated as well. The development trends and possible challenges to this design are also discussed. It is estimated that the proposed method costs approximately 49% of traditional coal mining costs. The UAMM-based in situ fluidized mining and transformation method will reduce CO2 emissions by at least 94.9% compared to traditional coal mining and utilisation methods. The proposed approach is expected to achieve safe and environmentally friendly coal mining as well as lowcarbon and clean utilisation of coal.

An Empirical Study on the Environmental Kuznets Curve for China's Carbon Emissions:Based on Provincial Panel Data

Based on the Environmental Kuznets Curve theory, the authors choose provincial panel data of China in 1990-2007 and adopt panel trait root and co-integration testing method to study whether there is Environmental Kuznets Curve for China＇s carbon emissions. The research results show that： carbon emissions per capita of the eastern region and the central region of China fit into Environmental Kuznets Curve, but that of the western region does not. On this basis, the authors carry out scenario analysis on the occurrence time of the inflection point of carbon emissions per capita of different regions, and describe a specific time path.

High speed railway promoting development of low-carbon economy in China

Low-carbon Economy is a kind of economic developing mode which takes low energy consumption,low pollution and low discharge as its foundation. It is another important revolution of the human society after the agriculture civilization and industry civilization. It deals with various fields including low-carbon energy,low-carbon agriculture,low-carbon industry,low-carbon transportation and low-carbon life,etc. Among those,low-carbon transportation is one of the important contents. Since high speed railway uses electricity as driving force,it runs without discharging waste gas,and it is a kind of clean and green transportation with little dust and smoke black. Therefore,the study of the relationship between the high speed railway and low-carbon economy is becoming one of the important frontier problems that confronting the theoretic circle. With demonstration analysis and comparative analysis,this paper discusses the comparative advantages of high speed railway in terms of energy saving and environment protection,treatment of sound pollution,land saving and reduction of external cost(mainly pollution treatment cost) ,etc. compared with the other transportation modes and ordinary railway. Taking Beijing-Tianjin Intercity Railway as an example,the paper further demonstrates the distinctive advantages in respect of energy conservation and emission reduction. Besides,the paper also predicates the low-carbon effects after several high speed railways is put into operation in a few years. It is concluded that the development of high speed railways will meet the need of low-carbon economy and is significant for sustainable and steady development of economy and society.

Coordinated Development Level of Economic Society and Ecological Environment in Binzhou City

Based on the data of GDP per capita and emissions of major pollutants in Binzhou City from 2013 to 2017,the changing trends of emissions of major pollutants with the increase of GDP per capita,as well as the coordinated development level of ecological environment and social economy in Binzhou City were studied.The results showed that with the increase of GDP per capita,the changing curves of industrial wastewater and industrial soot in Binzhou City were inverted-U-shaped,and the emission of industrial wastewater reduced after peaking.However,the production of industrial solid waste and the emission of industrial waste gas did not show a downward trend with economic growth,and still increased year by year.The coordination degree of economic development and ecological environment protection in Binzhou City was moderately lagged.By the adjustment of industrial structure,environmental protection and control should be increased,and relevant regulations should be formulated to control pollutant emissions,thereby achieving sustainable development and coordinated development of regional ecology and environment.

中国环境保护税促进经济绿色转型模式创新

该研究基于中国省际面板数据,对环境保护税促进经济绿色转型模式创新进行了研究。结果表明:环境保护税对绿色全要素生产率促进作用显著,对于绿色技术创新,市场激励型环境保护税影响系数由负转正,转换速度为12.0153;对于绿色经济,命令控制型环境保护税和市场激励型环境保护税影响系数由负转正。在市场激励型规制强度低于门限值低区制,随环境保护税强度增加,影响绿色技术创新表现为显著抑制作用。建议要将环境保护税强度适度提高,推行市场激励型环境保护税政策。在短期内,提高环境保护税强度会对企业盈利有不利影响,需政府将政策扶持力度加大,推行绿色技术研发补贴、返还排污费、对环境税等激励性政策。以此为基础,对公司进行产品的生产技术创新,从而达到降低污染的目的,推动经济增长方式绿色转型。

我国绿色环保产业“四链”融合发展研究

绿色环保产业兼具带动经济增长和应对环境问题的双重属性,“四链”深度融合是绿色环保产业实现高质量发展的重要支撑,是实现“双碳”目标的重要抓手。本文通过深度分析企业不同发展阶段“四链”融合特征,结合产业发展现状,发现在企业创立初期,资金链是关键,创新链与人才链驱动,逐步形成产业链;在企业成长期,主要靠资金链驱动,人才链与创新链支持,拓展产业链;而对于成熟期的企业,可依据产业链进行战略布局,维持创新链。研究发现,绿色环保产业“四链”融合主要存在创新链与产业链衔接不紧密、资金链对各链的支撑度较弱、人才链与创新链和资金链融合度不够等问题。研究建议,制定低碳创新战略路线图,明确“四链”融合发展路径;提高创新链与产业链适配度;优化资金链,提高与各链融合度;完善人才链,注重人才培育;企业根据自身发展阶段,明确驱动链,保障“四链”有效融合。

农村集体经济发展促进农民共同富裕的实现机制研究——陕西省袁家村的经验

发展壮大农村集体经济是实现农民共同富裕的关键路径,也是促进农民共同富裕的经济基础,但要实现农民共同富裕的目标,还必须有良好的制度保障和环境保障作为支撑。本文通过对陕西省袁家村走向共同富裕的案例进行解剖,讨论在共同富裕的微观实践中农村集体经济高质量发展如何推动农民走向共同富裕。研究表明:(1)农村集体经济发展壮大是促进农民共同富裕的物质基础,但这并不构成农民实现共同富裕的必然条件,要想实现“村庄强”和“农民富”的双重目标,还必须在发展壮大农村集体经济的前提下,构建科学的分配机制与治理环境;(2)农村集体经济发展受乡土社会结构和社会关系影响,因而在进行农村集体经济发展成果分配时必须充分吸收乡土社会运行规则,通过逆市场化的方式来推动分配机制创新,促进集体经济发展成果在村域内实现公平分配;(3)良好的村庄治理生态是实现经济可持续发展和集体成果公平分配的保障,因而在推动经济发展和集体收益分配的过程中,必须重视改善村庄治理生态,以此构建集体经济发展、农民共同富裕和村庄实现善治的良好格局。
