China-Japan International Input-Output Analysis: Focusing on Mutual Dependence between the Two Economies and on the Relationship between Japan's FDI and China's Industrial Structure

本研究的任务是建立中日国际投入产出对照表，并在此基础上对中日经济的相互依存程度进行定量分析，目的是为两国经济关系的政策提出建议。首先，我们编制了以2000年价格计算的1990-1995-2000年中日国际投入产出挂钩表（LCJIO）。在此基础上，重构了1995-2000年日本企业2000年价格下的国际投入产出表（LJEIO），分析了日本企业的经济活动。其次，根据这张国际投入产出表，我们明确了中日两国经济目前是相互依赖的，并明确指出了近年来这种相互依赖发生了什么变化。具体来说，我们分析了日本在中国的外国直接投资（FDI）对日本经济和中国经济的影响。进一步，通过关注FDI与中国产业结构的关系，我们解释了日本FDI在推动中国产业结构方面所起的作用。在迄今为止对中日经济关系的研究中，大多是通过理论或统计分析的方法。此外，在利用国际投入产出模型（International Input-Output Models）对日本的外国直接投资（FDI）进行的极为罕见的分析中，许多人分析了日本企业进军海外对国内产生的影响。在本研究中，与这些早期的研究相比，使用原始数据库来阐明中日经济关系以及近年来在华经营的日本企业。此外，在本研究中，我们可以解释日本企业在中国的直接投资是推动中国产业结构的重要因素之一。

The tasks for this research were to develop Linked China-Japan International Input-Output Tables and, based on this original database, to make a quantitative analysis of how interdependent the Chinese and Japanese economies are: The purpose was to derive suggestions concerning the policy for the economic relationship between the two countries. First, we prepared 1990-1995-2000 Linked China-Japan International Input-Output Tables at 2000 prices (LCJIO). Then, we reconstructed 1995-2000 International Input-Output Tables for Japanese Enterprises Analysis at 2000 prices (LJEIO) to analyze economic activities of Japanese enterprises. Next, based on this International Input-Output Tables, we made it clear that the Chinese and Japanese economies are mutually dependent at present and indicated clearly what changes this mutual dependence has undergone in recent years. To be specific, we analyzed how Japan's foreign direct investment (FDI) in China has influenced the Japanese economy and the Chinese economy. Further, by focusing on the relationship between the FDI and China's industrial structure, we explained the role Japan's FDI has played in advancing the industrial structure. In researches on economic relations between China and Japan made so far, most of the approaches were through theoretical/statistical analyses. Also, in those of the exceedingly rare analyses made using International Input-Output Models which focused on Japan's FDI, many analyzed what effects Japanese enterprises' into foreign advance has produced back at home. In this research, in comparison with these earlier researches, original database is used to elucidate the China-Japan economic relations and the Japanese enterprises operating in China have had in recent years. Further, in this research, we could explain that one of important factors in advancing China's industrial structure has been Japanese enterprises' FDI in the country.
