项目摘要

This study analyzes the economic impacts of transportation development/efficiency improvement, information technology introduction, and energy efficiency improvement as production-oriented infrastructure. It also offers important policy implications to transportation economic policy, information technology economic policy, and energy economic policy, and at the same time their interrelations including consequent environmental impacts. Since new venture industries with large influencing power cannot be expected nowadays such production -oriented infrastructure is a key to economic growth.Economic analysis in this study takes place in a general equilibrium context. Computable General Equilibrium (CGE) models are widely used to evaluate economic polices with structural impacts on various sector of economy While CGE models have been applied mostly for evaluating macro economic policies such sectors as trade and finance, this study applies the CGE models to evaluate specific policy of transportation, information, and energy for various aspects.The study also applied data envelopment analysis (DEA), vector autoregression analysis (VAR) and others without staying with the conventional analytical approach of social capital of, say, estimating aggregate production functions. This enables us to use new kinds of data and draw comprehensive conclusions. The study also discusses such policies not only from a macro point of view but also from regional economic points of view.The study identifies those production-oriented sectors with wide and intensive economic impacts with comprehensive economic impact assessment. The study also suggests that the economic impacts of transportation efficiency improvement and information technology introduction are not only large but also require inter-sectoral coordination taking into consideration energy and environmental issues.

本研究分析了交通发展/效率提高、信息技术引入和能源效率提高作为生产导向型基础设施的经济影响。它还对交通经济政策、信息技术经济政策和能源经济政策以及它们之间的相互关系（包括随之而来的环境影响）提供了重要的政策影响。由于如今无法指望具有巨大影响力的新创企业，这种以生产为导向的基础设施是经济增长的关键。本研究中的经济分析是在一般均衡背景下进行的。可计算一般均衡（CGE）模型广泛用于评估对各经济部门具有结构性影响的经济政策。虽然CGE模型主要用于评估贸易、金融等部门的宏观经济政策，但本研究将CGE模型应用于评估交通、信息和能源等各个方面的具体政策。研究还应用了数据包络分析（DEA）、向量自回归分析（VAR）等使用社会资本的传统分析方法，例如估计总生产函数。这使我们能够使用新类型的数据并得出全面的结论。研究不仅从宏观角度，而且从区域经济角度对这些政策进行了讨论。研究通过综合经济影响评估，识别出那些对经济影响广泛而密集的生产导向型部门。研究还表明，运输效率提高和信息技术引入的经济影响不仅很大，而且需要考虑能源和环境问题的部门间协调。
