大学评价问题是一个非常重要而又极其复杂的多目标评价问题.大学评价研究的结果不仅会受到高等院校、教育主管部门和企事业单位的普遍关注和高度重视,而且会对广大社会公众,特别是大中学生和学生家长产生重要而深远的影响.数十年来,西方发达国家的'大学评价热'始终'高温不退',各种'大学排行榜'也频频见诸报刊、电视等大众媒体;近些年来,大学评价热也在我国蓬勃兴起,一些研究者在大学评价的理论、方法及其应用研究方面进行了有益的探索,并且产生了一些具有广泛影响而又颇有争议的研究成果.广东管理科学研究院武书连先生等人1997年以来在等刊物上陆续发表的有关系列研究成果即是这类研究成果的典型代表.

区域高新技术产业可持续发展是一个比较复杂的理论问题,一方面,区域高新技术产业是一个由众多相关企业、高等学校、科研院所及政府部门和中介机构等构成的复杂的经济棗科技棗社会系统,其可持续发展不仅会受到各构成要素的功能水平(即可持续发展能力)的影响,而且会受到这些要素之间相互关系(即系统结构)的影响;另一方面,不同区域的高新技术产业在资源状况、经济基础、技术水平、创新能力、市场环境、政策法规及支撑服务体系建设诸方面可能千差万别,因而其可持续发展的道路与模式也不会'千篇一律'.因此,应当以某一(几)个典型的区域高新技术产业为研究对象,采用理论研究与实证分析相结合的研究方法,深入研究其可持续发展的影响因素、基本条件、主要障碍和实现途径等重要理论问题,并在此基础上归纳出区域高新技术产业可持续发展的基本规律,形成比较科学而完整的区域高新技术产业可持续发展理论,从而为区域高新技术产业的可持续发展提供科学的理论指导和具体的行动指南.
