How R&D investment promotes green technology innovation in the context of digitalization?-An empirical analysis based on provincial panel data

Green technology innovation is an important driving force and source to promote my country’s high-quality development,and it is the core path to achieve sustainable development.This paper uses my country’s provincial panel data from 2016 to 2019 to study the impact mechanism of R&D investment on green technology innovation,and introduces the level of digitization,using the panel threshold model to discuss its role in the impact mechanism of R&D investment on green technology innovation.The study found that when the level of digitalization in a region is low,increasing R&D investment does not necessarily improve the ability of green technology innovation;when the level of digitalization is relatively high,R&D investment has a positive role in promoting green technology innovation.Therefore,it is necessary to improve policies to encourage enterprises to increase investment in research and development;at the same time,it is necessary to promote the coordinated development of digital foundation,digital investment,digital literacy,digital economy and digital application,and promote the deep integration of digitalization and green technology innovation.

我国高放废物地质处置地下实验室安全问题探析

建造地下实验室是我国高放废物地质处置研发的必经阶段。作为场址特性和多重屏障长期性能研究、选址与长期性能评价,以及工程技术研发的平台,地下实验室为高放废物地质处置设施设计和建造提供基础科学信息和实践经验,也为安全评价提供基础数据。根据国家相关规划,2020年完成地下实验室建造的安全评审,但目前尚缺少相应的安全监管方法和审查要求。本文从地下实验室的功能和作用出发,基于我国地质处置地下实验室的功能定位,结合瑞典、芬兰、美国和法国等国家对地下实验室建设的相关要求和实践,阐述了地下实验室安全审查需要重点关注的几个关键问题,并提出了相关建议。

核电厂放射性废物管理同行评估初探

同行评估是提升核电厂运行管理水平的一种行之有效的科学手段,国内已针对概率安全分析和老化管理开展专项同行评估,但尚未就放射性废物管理开展评估。本文概述了国内外核电行业同行评估及放射性废物管理领域同行评估的方法及实践,分析了在我国开展核电厂放射性废物管理同行评估的必要性。结合国际核电厂及放射性废物管理领域的同行评估良好实践,提出我国开展核电厂放射性废物管理同行评估的建议。
