摘要
以DAG的同期因果关系为基础构造珠三角摩托车制造业集聚内部企业间的外溢效应模型并进行实证分析,结果发现企业之间正负技术外溢效应均存在,而规模拉动作用显著,说明不存在挤占效应;企业之间的规模差异影响外溢作用的强弱,如江门大长江集团及广州大阳摩托作为区域摩托车龙头企业,其外溢中心和吸收中心地位显著。
The paper constructs a spillover model and conducts an empirical analysis among motorcycle manufacturers in the Pearl River Delta based on DAG. Both positive and negative technological diffusion effects as well as significant scale promoting effect are found, indicating that there is no stealing effect on market occupancy. It is also discovered that compa- ny＇ s scale affects the strength of spillover effect. The study also suggests that two leading regional manufacturers, DCJ and DY, are major spilling and absorbing centers.
