A Mechanism for Digital Finance to Drive Green and Low-Carbon Development

Given the global focus on green and low-carbon development and the increasing prominence of digital finance,it is particularly important to explore how to leverage digital finance to achieve these environmental goals.This study,through mechanism analysis,deeply examines how China’s digital finance promotes green and low-carbon development and elucidates the positive interaction between digital finance and the green industry.The study found that digital finance,through more flexible and efficient financial functions,alters the cost structure of carbon emissions,and reduces the risks and costs of green investments,thereby creating a cooperative green mechanism benefiting all parties,and guiding social groups toward a green and low-carbon transformation.Additionally,the rapid development of digital finance has strengthened the implementation of environmental protection policies,effectively promoted the expansion of the environmental protection industry,and established the green ethos as a mainstream concept in financial development.This study aims to provide reference perspectives and suggestions,assist policymakers in promoting the green and lowcarbon development of digital finance,and offer insights into the integrated development of digital finance and the green environmental protection industry.

Synthesis and Characterization of β-Cyclodextrin Modified Biochar Environmental Remediation Materials

In this paper, biochar (BC) was used as raw material, activated by deionizing aqueous solution, NaCl solution, CA solution and HCl solution respectively. Epichlorohydrin (EPI) was used as crosslinking agent, and β-cyclodextrin (β-CD) was used to modify biochar (BC). The prepared modified biochar materials were labeled with β-CDBC, β-CDBC-Na, β-CDBC-CA and β-CDBC-H, respectively. The infrared spectrum, X-ray diffractometer, scanning electron microscope and specific surface area of the four modified materials were tested. The results showed that the C-O stretching vibration peak at 1020 cm−1 of the modified materials was slightly offset compared with that of biochar. The characteristic absorption peaks of XRD pattern decrease obviously at 2θ = 26.7˚ and 29.5˚. It can be obviously observed on the electron microscope image that the surface is loaded or formed clathrates, and BET data and graphs also show that the specific surface area of the modified biochar is larger. Therefore, β-cyclodextrin successfully modified biochar and formed clathrates on the surface of biochar or was loaded in the pore structure of biochar, especially β-CDBC-CA achieved better modification effect. Because biochar and β-cyclodextrin raw materials are cheap, easy to prepare and green, and less prone to secondary pollution, it has a good advantage in environmental governance.

Environmental Technical Standards and the Green Transition of China’s Manufacturing Industry

Distinct from the existing literature conforming to the Porter hypothesis which emphasizes the technological innovation mechanism,this paper examines the mechanism of technological transformation through which environmental technical standards influence the manufacturing industry in reducing emissions and improving efficiency(i.e.green transition).Furthermore,drawing upon enterprise samples from the databases of Chinese Industrial Enterprises and Chinese Industrial Pollution Sources from Major Monitored Enterprises,it empirically validates the results of the theoretical analysis.Overall,our research reveals that environmental technical standards can propel manufacturing enterprises to reduce pollution and increase productivity by following an incremental path of technological transformation,thereby achieving a green transition.Moreover,environmental technical standards indirectly promote green technology innovation in the upstream equipment manufacturing enterprises.Heterogeneity analysis further shows that environmental technical standards have a stronger effect of green transition on those companies with higher pollution emission intensity,lower productivity,slower capital renewal and stronger financing capacity prior to implementing the environmental policies.

Green Barriers： Obstacle or Stimulation ？

Most viewpoints in China consider green barrier is one kind of non-tariff barriers imposed by developed countries and is unfair to developing countries. Different from these, this paper points out that green barriers, evolving from the background of sustainable development theory and the principle of environment protection, have positive effect on ideology, international institutional arrangement and innovation stimulation. Demonstrating the rationality of green barriers, the paper puts forward that green barriers should be regarded as the stimulation for technology innovation and industrial restructure rather than obstacles. The best way to surmount the green barriers for Chinese government and enterprises is to implement circular economy and clean production so as to achieve the harmony of trade, environment and economic development.

The Stable Mechanism and Motive System for the Development of Green Enterprises

Green Enterprises are a modernized enterprise mode. The paper analyzes the internal stable mechanism and motive system for the sustainable development of green enterprises in three aspects： environment, culture and innovation. The paper discusses the three subsystems respectively in the light of green enterprises. The green innovation is not a static and stable system, but is always in a dynamic state of nonequilibrium, where the existing order is broken. Meanwhile, the great reaction of the green innovation on environment also brings about a great advance in the sustainable development of green enterprises.

Research and Application of an Environmental-Friendly Low-Damage and High Salt-Resistance Slick Water Fracturing Fluid System

The Sulige gas field is a typical low-pressure low-permeability tight sandstone gas reservoir. The reservoir has poor seepage capacity, strong heterogeneity, high mineralization of formation water and extremely scarce water resources on the site. These unfavorable factors have brought great difficulties to the on-site mining process. Now, a nano-composite green environmental protection slick water fracturing fluid system CQFR can be quickly dissolved because of the larger specific surface area, and the small molecular size makes the damage to the reservoir less than 5%, and the average drag reduction effect can reach more than 73%. It can quickly and well dissolve and maintain performance under high salinity conditions and fracturing flowback fluids. It responds well to the complex reservoir conditions on the construction site and makes the flowback fluid recyable, which greatly reduces the consumption of water resources on the construction site and effectively improves the construction efficiency and economic benefits.

A green eco-environment for sustainable development:framework and action

Following its 40-year reform and‘Open Door’policy,China has recently proposed a new approach to green development and rural revitalization—the idea of Agriculture Green Development(AGD),with the key feature of creating a green eco-environment.In this minireview we introduce the definition,theory,framework and major components of a green eco-environment as a key part of the AGD.We define a green eco-environment as including four key elements or measures:(1)a green ecoenvironmental indicator system;(2)environmental monitoring and warning networks;(3)emission standards and environmental thresholds for key pollutants;(4)emission controls and pollution remediation technologies.We have used Quzhou County(a typical county in the center of the North China Plain)as an example to show how detailed air,water and soil monitoring networks,as well as improved farmer practices and pollution control measures(especially ammonia emission mitigation and PM2.5 pollution reduction),can begin to create a green eco-environment in China and that AGD is possible.We conclude by stressing the need to improve the framework and practice for a green eco-environment,especially the importance of linking proposals and practices for a green eco-environment with the United Nations high priority Sustainable Development Goals.
