| 中文摘要: |
| 研究目标：在中国区域经济发展不平衡背景下，探究中国地区经济差距及其影响因素。研究方法：选取1978～2017年省际数据，采用Dagum基尼系数测度中国地区经济差距，使用二次指派程序（QAP）对地区经济差距的影响因素进行实证分析。研究发现：中国地区经济差距总体呈现“下降—上升—下降”趋势。地区间差距和地区内差距分别为“东中西”和“南北”地区经济差距的主要来源。“东西”方向地区之间经济差距大于“南北”方向。全样本QAP回归结果表明，人均资本、城镇化水平和对外开放程度等数量型因素是影响地区经济差距的主导力量，而全要素生产率和人力资本等质量型因素对地区经济差距的影响并不显著。基于分时期、分年度和分地区的QAP回归结果存在异质性。研究创新：从“东中西”和“南北”两个视角，全面、系统地测度中国地区经济差距变化趋势，并识别差距形成的内在机理。研究价值：揭示中国地区经济差距的演变趋势和差距来源，为缩小地区经济差异、推动中国区域协调发展提供依据。 |
| 英文摘要: |
| Research Objectives: Under the background of unbalanced regional economic development in China, the paper explores China‘s regional economic gap and its influencing factors. Research Method: Based on the provincial data from 1978 to 2017, the Dagum Gini coefficient was used to measure the regional economic gap in China, and the influencing factors were empirically analyzed by using QAP. Research Findings: The results show that the overall regional economic gap in China presents a downward-upward-down trend. Interregional gap and intra-regional gap are the main sources of economic gap in East-West and North-South respectively. The economic gap between East-West is larger than that between North-South. The QAP regression results based on full sample show that the quantitative factors such as per capita capital, urbanization level and opening-up degree are the dominant forces affecting regional economic gap, while the qualitative factors such as TFP and human capital have no significant impact on regional economic gap. There is heterogeneity in QAP regression results based on period, year and region. Research Innovations: From the perspectives of East-West and North-South, the paper measures the trend of China‘s regional economic gap more comprehensively and systematically, and identifies the internal mechanism. Research Value: The results can reveal the evolution trend and influencing factors of China‘s regional economic gap, and provide a basis for narrowing regional economic gap and promoting China‘s coordinated regional development. |
