Economic Implications of CO2 Emission Reduction in Japan Applying a Dynamic CGE Model with Endogenous Technological Change： Use of Emission Permit Revenue

This study analyzes the economic and environmental impacts of a climate change measure in Japan using a single-country dynamic computable general equilibrium model with technological change as an endogenous variable. In this way, a comprehensive analysis of the relationships between climate change and its measures, technology, and economy has been done. The model uses technological change as the accumulation of knowledge capital that is derived from research and development investment. The study investigates the impacts of a climate change measure considering the use of emission permit revenue and technological change induced by the policy implementation in the Japanese economy. Simulation results show that there is compatibility between CO2 emission reduction and positive effects on GDP that depends on the ways of the revenue use and technological change induced by emission reduction. However, it is not possible to find the ways to realize positive effects on both GDP and welfare simultaneously in the study. The sensitivity analysis for the elasticity of substitution between knowledge capital and other inputs also confirms the obtained results.

技术经济安全:研究重点、演化机理和评估框架

在新一轮科技革命和产业变革背景下,技术经济安全相关议题成为主要国家和地区共同关注的焦点。文章从学科建设视角,围绕“为什么”“是什么”“如何评”等关键问题开展基础理论研究,分析了关注技术经济安全的重要性和紧迫性,提出了技术、企业、产业、国家和区域等不同层面应重点关注的技术经济安全关键议题,构建了由环境诱发、要素传导、多重反馈和时空演化4个环节构成的技术经济安全发生和演化机理框架,并在此基础上形成了技术经济安全评估的TMAPS(技术-市场-主体-政策-安全)模型和指标框架。该研究工作有助于进一步理清技术经济安全的内涵和边界,并为加强技术经济安全评估、保障技术经济安全水平提供理论方法支撑。
