摘要
本文首次将对我国干中学的研究从宏观层面拓展到微观层面,利用1999—2007年的大样本企业数据测算了我国465个四位码制造业的干中学学习率,并在Sutton(1991)内生性沉没成本理论的框架下检验了干中学对我国制造业市场结构的动态影响。研究发现,中国制造业现阶段干中学的学习率呈现整体较高、行业之间差异较大的特点;干中学作为一种内生性沉没成本确实具有进入阻止的作用,能够提高行业的市场集中度,减缓我国制造业在市场规模扩张过程中市场结构趋于分散的态势,而且,干中学对我国制造业市场结构的影响大于另两种典型的内生性沉没成本——研发和广告。为优化我国制造业的市场结构,政府应当下大力气保护企业投资内生性沉没成本的激励,对产业市场结构的干预应当充分考虑各个产业在干中学强度上的差异,并采取有效措施降低干中学对研发的挤出。
The paper use the large sample enterprise data from 1999 to 2007 to calculate learning by doing rate of 465 four yards manufacturing of China and inspect learning by doing lead to the dynamic effect of Chinese manufacturing under the framework of Sutton （1991） endogenous sunk cost theory, which take Chinese learning by doing research from the macroscopic level expanded to the micro level first time. The research finds that the learning by doing rates in Chinese manufacturing are comparatively large but much difference between different industries. Actually the learning by doing have the effect to prevent and improve industry market concentration, which slowing down the situation of market structure tends to decentralize as the process of scale expansion. In addition, the learning by doing in Chinese manufacturing sector of the market structure greater .influence than the other two typical endogenous sunk costs, research and development, advertising. For optimization of Chinese manufacturing industry market structure, the government should protect enterprise investment with the goal of endogenous sunk cost incentive, and take effective measures to reduce the extrusion of the learning by doing to research and development based in considering the learning by doing industries differences.
