ABSTRACT

The objective of this study is to verify whether the additionality effect of the public subsidy varies depending on the nature of subcontracting regimes in which manufacturing Small and medium-sized enterprises (SMEs) are subcontracted to large firms. This study adopted the propensity score matching method using inverse probability weights to estimate the average treatment effect on the treated. This research found that the effects of the public subsidy on the input, behavioural, and output additionality varies depending on the subcontracting regimes in manufacturing SMEs. This study also shows that the lower the hierarchical position within subcontracting regimes the more effects of the public subsidy on the input and output additionality are reduced, signalling that the lower the hierarchy of the subcontracting regimes, the less the effectiveness of public subsidy in promoting innovation of SMEs. The results imply that the position of SMEs embedded in subcontracting regimes needs to be considered to mitigate factors that inhibit innovation to correct market failures and improve the knowledge spillover. Further, this study suggests that SMEs need to establish the optimal innovation strategy that can leverage their capability and resource dependence with consideration of their position in the subcontracting regimes.

摘要

本研究的目的是验证公共补贴的额外性效应是否会因制造中小型企业 (SME) 分包给大公司的分包制度的性质而异。本研究采用倾向评分匹配法，使用逆概率权重来估计治疗对治疗的平均效果。这项研究发现，公共补贴对投入、行为和产出额外性的影响因制造业中小企业的分包制度而异。该研究还表明，分包制度中的等级地位越低，公共补贴对投入和产出额外性的影响就越小，这表明分包制度的等级越低，公共补贴对促进中小企业创新的有效性越低。结果表明，需要考虑嵌入分包制度的中小企业的地位，以减轻抑制创新的因素，从而纠正市场失灵并改善知识溢出。此外，本研究表明，中小企业需要制定最佳创新战略，以利用其能力和资源依赖性，同时考虑其在分包制度中的地位。
