基于Bain Joe S传统产业组织理论的结构-行为-绩效(SCP)范式,运用对比分析、主成分分析、非参数检验等方法对四川省和广东省的制造产业进行区域优势比较。结果显示:两省制造业产业结构相似系数为51.1%,存在较大差异,四川省的传统产业结构偏重、资源依赖性强、新兴产业技术水平和盈利能力偏低;而广东省在技术含量高、附加值较大的技术型、信息性产业以及利用外资能力方面较强,四川和广东两省存在区域合作互补的潜力。
This article critically examines three most influential learning theories that underlie the instruction and learning environments in second language learning (SLL). Evaluation follows the description of each theory. The point is to understand the impacts of different theories on second language learning. The paper argues that an integrated approach, which combines the three theories, is needed.
