中国企业参与垂直分工会促进其技术创新吗?

Does Vertical Specilization Promote Chinese Enterprises' Technology Innovation?

研究目标:研究中国企业参与垂直分工会对其技术创新产生何种影响。研究方法:利用2000~2013年中国工业企业数据库与海关贸易统计库匹配数据测算中国企业的垂直专业化指数(VSS),继而实证分析垂直分工对不同所有制、贸易类型及组织模式的企业技术创新的影响。研究发现:中国企业的VSS从2000年的0.48下降至2013年的0.27;整体来说,中国企业参与垂直分工对其技术创新产生了显著的抑制效应;区分所有制、贸易方式和组织模式后发现,垂直分工对外资企业、加工企业及外资加工企业的创新抑制效应最大。研究创新:在Upward等(2013)和张杰等(2013)关于VSS测算方法的基础上进行了改进。研究价值:支撑了中国目前实施的"做强一般贸易、扩大一般贸易规模"的政策。该政策虽然使得企业的垂直分工程度不断下降,但不会削弱其技术创新能力。

Research Objectives： The effect of vertical specilization on Chinese enterprises＇ technolo- gy innovation. Research Methods： By merging China＇s manufacturing enterprises database and China＇s customs trade statistics database from 2000 to 2013, we calculate index of verti- cal specialization index （VSS） and empirically examine the effect of vertical specilization on Chinese enterprises＇ technology innovation. Research Findings： The VSS of Chinese enterpri- ses decreased from 0. 48 in 2000 to 0. 27 in 2013; the vertical specilization has a significant depression effect on the innovation of Chinese enterprises; There is the largest depression effect of VSS on the innovations of foreign invested, processed and foreign processed enter- prises respectively. Research Innovations： We improve the calculation index of VSS. Research Value： The policies, which China strengthens the general trade and expands the scale of general trade, continually make enterprises＇ VSS declining but not dampen their technology innovation capacity.
