服务业创新的新熊彼特定义：基于新分类法的概念探讨

创新是一项复杂的过程并具有多面性。在众多以创新与生产率之间联系为主题的研究中，由于数据限制，往往只采用单一指标来测度创新。本文对这种方式提出了质疑，认为这种研究方法可能会系统地偏向于某类经常通过参与创新活动以达到各种商业目的的公司或产业。为了更好地测度创新，本文介绍了一种创新索引，即以潜变量模型为基础的含有多项创新指标的线性指标组合。这一尝试得到加拿大制造业公司的大量微观数据组合的支持。     

Partnership Programs in U.S. Schools: Their Development and Relationship to Family Involvement Outcomes

This study examined data from over 300 U.S. schools on their efforts to develop high quality programs of school, family, and community partnerships. Analyses show that elementary schools, schools with greater support from parents, teachers, and the community; and schools that evaluated progress reported higher quality partnership programs over time. Higher quality programs were associated with wider implementation of parent-child interactive homework, higher levels of parent volunteering, and more parents on school decision-making committees. Results identify factors that could help schools develop quality partnership programs and suggest that these programs translate into higher levels of family involvement in students’ learning.
