本文利用改进的APG模型框架对中国各省份地区制造业部门生产效率增长进行分解和测算,并针对导致制造业要素配置效率低下的动因进行深入分析。研究显示,技术效率和企业净进入是推动制造业生产效率增长的主要来源,而要素配置效率对制造业生产效率增长的贡献非常有限,由此验证要素市场的发展滞后是造成中国经济增长乏力的重要内在因素。进一步的检验发现,地方政府对要素市场的干预是造成制造业要素配置效率低下的主要动因,这种干预效应总体上呈现倒U型关系。更为细致的分解结果表明,政府干预对于资本要素配置效率的作用效应呈倒U型关系,而对劳动要素配置效率呈U型关系。这些检验结果均证明,全面推进要素市场的市场化导向改革,减少政府干预对微观经济部门的扭曲性影响,是维持中国制造业生产效率可持续增长的重要改革措施。
This paper decomposes and estimates the province-level APG of manufacturing sector, and deeply analyzes the reasons of low allocative efficiency of factors in manufacturing sector. The empirical results show that, technical efficieney and net entry of firms are the main sources of APG of Chinese manufacturing sector, while the contribution of allocative efficiency of production factors to APG is limited, which proves that the backward development of factor markets is an important reason of slow growth of Chinese economy. Further tests show that, the intervention of faclor markets by local governments is the main driver of low allocative efficiency of manufacturing sector, and the intervention effect mainly manifests as inversed-U shape. More detailed decomposition results show that, the effect of intervention on the allocative efficiency of capital is inverted-U shape, while the eftect on the allocative efficiency of labor is U shape. All the tests above prove that, comprehensively promoting market-oriented reform of factor markets and reducing the distorted effect of government intervention on microeconomic organizations are the vital reform measures to maintain the sustainable growth of manufacturing APG.
