数字化与企业绿色创新表现——基于增量与提质的双重效应识别

数字化赋予了国民经济与微观企业转型升级的动能。文章在对上市公司进行文本挖掘的基础上,综合MD&A部分数字化词频占比和无形资产数据等多个数据集以提高企业数字化指标的刻画质量,实证考察了其对企业绿色创新表现的影响。研究发现,数字化对企业绿色创新表现具有"增量提质"的双重效应,并且该结论在创新性地采用清朝城墙数据作为历史工具变量和国家级大数据试验区建设作为准自然实验等一系列稳健性检验后仍然显著成立。异质性分析表明,这一促进效应在政府环保补助较高和内部管控成本较低的企业、非重污染行业企业中更为明显;而当地环境治理和知识产权保护则为该过程的实现提供了支撑。机制分析表明,数字化作用于企业绿色创新的路径依赖于其缓解了(环境)信息约束问题,促使企业自主参与环境治理,并有效提升企业商业信用。文章研究不仅为理解数字技术发展对企业绿色创新表现的影响机理提供了微观实证依据,也为未来实现数字化与"双碳"目标的"共赢"提供了重要启示。     

并行工程视角下产品绿色设计评估模式构建

环保性的相关决策及绿色产业是未来企业实现可持续发展所必须重视的议题。因此,运用并行工程的概念构建了一套新产品进行绿色设计时评选开发方案的评估模式,并结合模糊理论及灰色系统的理念与方法以处理决策过程中可能存在的不确定性、模糊性及评估过程中信息不完整性的情况,最后以模拟的方式完成此评估模式。     

THE IMPACT OF GREEN REVOLUTION ON RICE PRODUCTION IN VIETNAM

The current paper reviewed the development of the Green Revolution in Vietnam, using long‐term regional yield and modern variety adoption statistics, as well as household data collected in 1996 and 2003. The present study indicates that the Green Revolution began in irrigated favorable areas and spread to the less favorable areas in Vietnam such as in other Asian countries. What is unique in Vietnam is that although the Green Revolution ended in the mid‐1980s in the Philippines and Indonesia, it has still been sustained as of 2003. Our analyses revealed that such growth had been supported by continuous improvements of modern varieties by regional research institutes. The varieties imported from China have contributed to the Green Revolution in northern Vietnam and those developed by the International Rice Research Institute in southern Vietnam. The national agricultural research systems have also played a critically important role in developing location‐specific and appropriate technologies.     

基于循环经济的绿色产业发展探讨

以“减量化、再利用、再循环”为准则的循环经济理念是各行各业制定“十一五”规划的重要指导思想。因此,构建基于循环经济的绿色产业链,即由绿色信息产业、绿色宣教产业构成的软性绿色产业和由绿色资源产业、绿色制造产业、绿色流通产业构成的硬性绿色产业,必然以循环经济为指导,使企业顺应宏观环境的变化,抓住新的商机,大力发展绿色营销,进而促进我国循环经济的发展。     

城市创新行为改善生态效率了吗？——基于空间关联与溢出视角的考察

文章在理论层面探讨了创新对生态效率的影响机制，并基于城市空间关联与溢出视角，采用我国2007-2016年260个城市面板数据，运用空间计量模型检验了创新对生态效率的影响效应及多维度的城市异质性。进一步地，文章还通过对不同距离阈值上的创新空间溢出效应进行估计，测算了创新空间溢出的距离边界，检验了创新空间溢出驱动城市绿色发展的最佳地理距离区间，从而为增强区域创新合作以提升区域整体绿色发展水平提供了可供参考的量化依据。研究发现：总体而言，创新具有的增长效应、资源与环境效应、结构优化效应是促进城市生态效率改善的重要途径，且产出端创新对生态效率的驱动效应强于投入端创新；但创新对生态效率的影响具有显著的城市异质性，依赖于城市区位、所在城市群、环境政策、资源禀赋、创新能力和市场化水平；城市创新行为具有显著的空间溢出效应，但空间溢出随距离变化呈衰退趋势，350公里以内为创新活动的密集溢出区；生态效率也具有明显的空间溢出效应，经济越发达且联系越紧密、要素流动越自由、创新对生态效率驱动效应越强的地区，生态效率的空间溢出也越强。因此政府应完善创新激励政策、为创新外溢创造良好条件、注重引导创新的方向，并根据区域及城市发展实际，采取差异化的创新驱动绿色发展策略。     

泰安市环境污染损失对GDP的修正核算

经济的发展和不断增长的GDP数字,是建立在资源环境不断透支的基础之上的,这种高消耗、高污染的发展方式使社会不能承受环境污染造成的风险。采用污染治理成本法对泰安市环境污染成本进行了核算,结果表明泰安市2006年环境治理成本占当年GDP的1.03%,10.45亿元属于虚增值,泰安市2006年绿色GDP为1001.75亿元。

Drivers and barriers to environmental supply chain management practices: Lessons from the public and private sectors

This study explores the factors that drive or hinder organisations to implement green supply chain management initiatives. A literature review identifies the main categories of internal and external drivers of green supply chain management practices, including organisational factors, regulation, customers, competitors and society, but there is little indication of suppliers as drivers for green supply chain management. Internal barriers include cost and lack of legitimacy, whereas external barriers include regulation, poor supplier commitment and industry specific barriers. An explorative study is conducted based on interviews from seven different private and public sector organisations. Encouragingly, across the organisations, more drivers than barriers to environmental supply chain management are identified. Organisations seem to be more influenced by external rather than internal drivers. The barriers to environmental supply chain management experienced by organisations tend to be both internal and external.

The effects of agglomeration externalities on urban green total-factor productivity in China

For China's urban industrial layout and green development, determining which types of agglomeration externalities are most advantageous to the rise of green total-factor productivity has both theoretical and practical relevance. This research experimentally studies the effects of three types of agglomeration externalities on urban green total-factor productivity using the data of 285 Chinese cities from 2003 to 2018. The findings demonstrate that urban green total-factor output is rising, albeit with certain differences during different time periods. Both the Jacobs externality and the Porter externality are favorable for increasing urban green total-factor production when all cities are evaluated together, although the latter has a stronger promoting influence. The effect of the Marshall-Arrow-Romer externality, on the other hand, is not significant. Furthermore, these effects also depend on the stage of economic development and population size.
