文章将“一带一路”倡议视为准自然实验,以2009~2022年中国沪深A股上市企业为研究对象,采用双重差分法评估“一带一路”倡议对企业EsG表现的影响。结果表明,“一带一路”倡议显著提升了企业EsG表现,彰显了中国在共建“一带一路”过程中的负责任大国形象。渠道检验表明,“一带一路”倡议可以通过缓解企业融资约束和促进企业数字化转型两个渠道提升企业EsG表现。异质性分析表明,“一带一路”倡议对企业EsG表现的提升作用在重点合作行业、重污染合作行业、国有企业、非节点城市企业中表现更强。文章为推进“一带一路”倡议实施和提升企业EsG表现提供了借鉴。

The starting point of this research is the urban model promoted by the United Nations through the sustainable Development Goals(sDGs).The importance of public spaces is especially highlighted in Goal 11.7:“provide universal access to safe,inclusive,and accessible,green,and public spaces.”The quality of public spaces can be properly assessed by reconsidering the quality indicators and investigating their development potential,which is the main focus of our *** study is based on a theoretical and methodological reflection on the quality of public space,considering the contributions of some contemporary urban traditions and a few recent *** this perspective,a variety of public space projects developed in the European sphere have been selected and *** quality parameters identified in this initial analysis were then applied to the analysis of nine representative case studies in three spanish cities(Madrid,Barcelona,and Zaragoza).The main goal is to propose a methodology that helps to evaluate the quality of those public spaces and determine its relationship with the safety,accessibility,and inclusiveness conditions they offer.

Three turbot groups were kept at 15℃ - 16℃ (Cold Temperature, T), 17℃ - 18℃ (ambient T) and 21℃ - 22℃(warm T) during the larval development in order to study the thermal influence on muscle growth and larval development in this species. During the early stages (2 - 6 days of post-hatching), the body and the muscle growth was scarce, although the hyperplasia increased slightly, being higher at ambient and at cold T than at warm T. In contrast, the highest value of hypertrophy was found in the warm group. At 15 days of age, the body length and muscle growth increased in all the groups, being significantly higher in the warm than in the rest of groups. Thus, the highest values of both the hypertrophy and the hyperplasia of the white muscle fibres were reached at warm T, although it was only significant for the hyperplasia. The end of the metamorphosis was reached at 29 days of age in the warm group, whereas in the rest of groups it was no observed yet. At this developmental stage, the warm group showed the typical morphological mosaic of the myotome, and it was accompanied by an increase of the transverse area of the white and the red muscles, parallel to an increase of both the hypertrophy and the hyperplasia of the muscle fibres. The hyperplasia of the white fibres was the parameter most significantly increased. Also, the body length increased significantly in this group, reaching ≈ 1.6 cm at this stage.
