基于灰色关联理论的FDI和中国区域经济发展差距研究

Analysis of FDI and Chinese regional economic discrepancy using grey incidence theory

利用1998-2006年的时间序列和横截面数据,首先基于基尼系数测度了GDP、固定资产投资额、出口额、FDI和技术市场成交额区域分布的不平衡性;在此基础上,运用灰色关联理论分阶段实证分析了不同影响因素和地区经济发展差距之间的关系.结果表明:以不同的指标进行衡量,区域经济发展的不平衡程度也不一样;虽然在"入世"前后有所变化,但FDI的区域分布差异是造成东部、中部、西部区域经济发展不平衡的重要因素.

Economic discrepancy of the east,mid and west areas in China is enlarging in recent years, which is closely related to the distribution of foreign direct investment（FDI）.Using the time-pooling and cross-section data between 1998 and 2006,the regional distribution imbalance of GDP,investment in fixed assets,export,FDI and transaction value in technical market are measured based on the Gini Coefficient. Then the relationship between different factors and the regional economic discrepancy are empirically analyzed by stages using the grey incidence theory.It is found that the unbalancing degree of regional economy is different with diverse index,and though different before and after entering WTO,the regional distribution imbalance of FDI is a significant factor causing the regional economic discrepancy of the east, mid and west areas.
