近十余年来,创新一词不绝于耳,从中央到地方,创新型国家、创新型城市、创新型政府、创新型企业等说词众多。但是,真正的创新成果及其推广应用不尽人意。何以如此,最基本的一点,人们对创新的诠释不一,对创新的认识有待进一步提高。早在一百多年前,创新理论的创始人熊彼得就指出:创新是经济发展的内在力量,就是将从未有过的生产要素和生产条件的新组合引入生产过程。 In the past decade or so, there has been a continuous stream of innovations, from the central government to local governments, innovative countries, innovative cities, innovative governments and innovative enterprises. However, the true achievements of innovation and their promotion are not satisfactory. Why so, the most basic point, people are different interpretations of innovation, innovation needs to be further improved. As early as more than one hundred years ago, the founder of innovation theory, Schumpeter, pointed out that innovation is the inherent force of economic development, that is, it introduces an unprecedented combination of factors of production and production into the production process.

判断函数单调性时易忽视的一种特殊情况  例1 已知函数[fx=-13x3+ax2-x-1]在[R]上是减函数,求实数[a]的取值范围.  错解 [fx=-x2+2ax-1],因为[fx]在[R]上是减函数,所以[fx<0]在[R]上恒成立,即[Δ=4a2-4<0],解得[-1  正解 [fx<0]恒成立的充要条件并不是[fx]在[R]上是减函数.  事实上, 当[a=1]时,[fx=-x-12].
