By using cobb - douglas production function model and solow ' s growth equation , this paper computes and analyses the effect of technological progress on shunde ' s economic growth since 1990s , summarizes the characters and defects of shunde ' s technical development and points out technological progress become the vital factor and high - tech industry largely promote its progress 本文运用柯布道格拉斯生产函数模型和索洛增长速度方程式，对顺德90年代以来技术进步及其对经济发展的贡献进行实证分析，指出技术进步已成为顺德经济发展的主要动力，概括了顺德技术进步的特点及存在问题，认为顺德高新技术产业的快速发展是发挥技术进步作用的重要原因。
Around this , firstly , this paper defines the concept on the smes and the sustainable development of the smes , explains the reasons that the smes can develop sustainablely . secondly , this paper analyzes the character and the present situation of the smes in china , appraises the economic benefit by using the cobb - douglas function , shows the present questions from three sides : outer entire questions , inner management problems and environmental pollution problems , testifies the problems through the real example 围绕这一问题，本文首先在给出中小企业的定义后，界定中小企业可持续发展的内涵，探讨中小企业须可持续发展的原因；接着深入分析了我国中小企业的特点与发展现状，运用cobb ? douglas生产函数评价我国中小企业经营经济效益，揭示我国中小企业可持续发展过程中面临的问题：宏观整体存在的问题、内部经营存在的问题及环境污染的问题等，随后用典型案例加以实证分析。
The presence of a cointegrating relationship between output and inputs , represented by either a two - factor cobb - douglas production function or a three - factor cobb - douglas type , depends crucially on whether country - specific intercepts and country - specific time trends are accounted for 实证分析显示产出与投入之间同积关系的存在与否?不论这种同积关系是由二要素还是由三要素柯布?道格拉斯生产函数来代表，关键取决于各国经济发展的独特初始特徵和独特时间趋势特徵是否被考虑到。
The frontier production function , a parametric function of any form , can be estimated by sample data . this study shows that the projected panel data , which is the inputs and relative exponential maximum output data set , obtained by conducting the data envelopment analysis with the log inputs and output , is approximately piecewise cobb - douglas under a certain assumption 根据前沿生产函数的定义,本文利用投入产出的对数形式和数据包络分析方法求出了相对指数最大产出,并证明了在一定的条件之下,这种数据结构即所谓的支撑面板数据具有分段近似cobb - douglas性。
This paper make a logarithm model of cobb - douglas produce function by the relation of elasticity of capital and labor and scale effect of cobb - douglas produce function , and for the first time use this model to research demonstration of 30 kind of mainly industry of guangdong , and elicit conclusion 本文利用cobb - douglas生产函数中关于资本弹性、劳动力弹性与企业规模效应的关系，构建了cobb - douglas生产函数的对数模型，并利用此模型首次对广东省30个主要的工业行业进行了实证研究，并得到了以下结论。
