摘  要: 采用中国多区域投入产出(MRIO)模型,定量核算了2007年中国八大经济区域投资活动所诱发的经济增长拉动和能源消耗双重效应。结果表明:各区域投资活动的拉动经济增长效应外溢现象明显,能源消耗强度指标也呈现明显区域化差异,如京津、东部沿海、南部沿海承接的经济拉动效应的能耗强度最低,经济增长的能源效率较高。认为当前区域投资政策的制定需充分考虑经济增长拉动的外溢性和资源环境的硬约束。
 
关键词: 多区域投入产出(MRIO);固定资本形成;经济增长;能源消耗

Abstract: In this study, China’s multi-regional input-output (MRIO) model is adopted to quantify the two effects: economic boost and energy consumption. In the model, China mainland is divided into eight major economic regions, and fixed capital formation vector is used to measure regional investment scale and structure. The results have shown that the sort of the economic boost and total energy effects is the same as the size of regional economies, that the considerable part of the total effect is spilled over to other regions, and that a large proportion is spilled over to the rest of world (ROW). For example, the energy efficiency of Beijing and Tianjin, east coast, the southern coastal regions undertake economic boost effect with the lowest energy intensity, and northwest region undertake economic boost effect with the largest energy intensity, namely the lowest quality. These findings suggest that the development of regional investment policies should fully consider the spillover effects of economic boost and environment costs. In summary, the findings may provide some valuable data for the regional investment policy-making.
 
Key words: multi-regional input-output(MRIO); fixed capital formation; economic growth; energy consumption
