经济发展实践使人们越来越清醒地认识到科学技术在经济发展中的巨大推动作用。世界各国，尤其是发达国家科学技术的进步在国民经济增长中占据比重越来越大。美、日、德等发达国家科技进步贡献率高达70~80%，而我国1979~2000年，这一贡献率不到30%，而且东西部地区还存在很大的差距。 特别是地处西部的科技大省——陕西省科技进步贡献率低，己经成为制约陕西经济实力和竞争力的“瓶颈”。因此，本研究旨在通过精确测度和分析陕西经济总体科技进步贡献率，对比其他省份的情况，找出制约陕西科技进步最根本的原因，解答“陕西科技经济发展之谜”，并对此提出相应的对策。 本文使用C-D生产函数及索洛余值法测算了陕西省及其它对比经济单元1985—2001年经济增长中的科技进步贡献率。其中参数a和β的估算采用了灰色关联的方法，经济量使用统一的统计口径和统一的计算方法，用环比增长率来计算各经济量的增长速度。 对本课题的计算结果进行了分析，得出以下结论： 1. C-D生产函数及索洛“余值法”适应于本研究选取的经济单元的科技贡献率的计算；统计数据处理方法及参数a、β的估算方法是科学准确的和符合实际的。 2. 本文测算的陕西省1985~2001年科技进步贡献率为35.3%，低于北京的科技贡献率（43.3%）和广东省（42.8%），略高于中部省份湖北（33.4%）和全国平均水平（30.8%），比同属西部的宁夏回族自治区（10.8%）高得多，这个结果比较客观、公正地反映了陕西省这些年来的经济发展实际情况。 3. 通过对测算结果和陕西的经济实际情况分析，我们还可以得知：我国2003年新经济指数排名陕西省位于全国第八位，而人均国民生产总值排在29位，陕西省独有科技优势和资源优势还远未转化为经济优势。 最后，就如何使陕西的科技优势最大限度地转化为现实生产力，使科技优势转化为经济优势，使科技大省成为名副其实的经济强省，笔者建议从以下几个方面抓起：树立新的科技开发观念、建立科技创新的动力机制、建立科研经费保障机制、建立科研人员保障机制、营造公平竞争的市场环境，科技资源分配尽可能地公开，使资源得到较高效率的配置和使用，同时，依托陕西的优势资源，进行技术改造和科技渗透，以创造出更高的效益。 本研究具有以下创新点：一是使用先进的研究方法，把计算机计算和新的数学方法相结合，使计算简单化、准确化；二是使用了先进的研究思路，把陕西省和其他地区置于同一系统内，使用同一的数据处理方法和统计口径，使计算结果更科学、更符合实际，且具有可比性。 应用本研究中的计算方法可以方便、科学、准确地测算其他各经济区的科技进步贡献率，有较好的应用前景。

The practices of economy development make people more and more conscious that science & technology has great function in promoting economy to develop. Every nations, particularly developed ones, their weights of the advance of technology in the increase of national economy is more and more big. The contribution rate of technology advance is amount to 70~80% in developed nations such as America, Japan, Germany etc., but this rate isn’t attain 30% in China from 1979 to 2000, and there is very big margin between the east and west region. Especially, the low contribution rate of technology advance of the big province--Shaanxi province in western region has already become a " bottleneck" of restricting his economy and competition power advancing. Therefore, this research aims at finding out the most basic reason which restricts technology of Shaanxi progressing, explaining the riddle of technology and economy of Shaanxi development, bringing up the counter-plan, through the precise measuring and analyzing the total contribution rate of technology advance of Shaanxi, and contrasting with other regions. The dissertation calculated the contribution rates of technology advance of Shaanxi province and other contrastive economic unit from the year 1985 to 2001 by using the C-D Produce Function and Solow Residual Method. The estimating method of the output elasticity of labor (a) and the output elasticity of capital (β) is the method of gray connection, measuring the economy quantity with the united statistic caliber and united calculation method, computing the increasing speed of economy quantity with loop ratio increasing rate. Through analyzing the calculated result of this task, the writer drew conclusion as follows: (1) C-D Produce Function and Solow Residual Method are adapted in computing the contribution rates of technology advance of these economic units that select by examinations in this research; The method of handling statistics datum and the estimating method of the output elasticity of labor (a) and the output elasticity of capital (β) are scientific, veracious and according with fact. (2) The contribution rates of technology advance of Shaanxi province in the year 1985~2001 is 35.3% according this dissertation, which is lower than that of Peking (43.3%) and Guangdong province (42.8%), slightly higher than that of central part province Hubei (33.4%) and also higher than national average level (30.8%) , much higher than that of the Ningxia Hui Autonomous Region (10.8%), which also belong to the western region. This result reflected the actual economic development of Shaanxi province of these last years objectively and equitably. (3)Through analysis of the calculate results and actual fact of Shaanxi province, we can still attain below information: The latest rank of index of new economy in China shows: Shaanxi is the eighth, but the GDP per person is NO.29, so the technology and resource advantages of Shaanxi are far to convert to economic advantage, Finally, how to make the technology of the Shaanxi converting to realistic productivity farthest, and make the technology advantage converting to economic advantage, and make the big province of technology becoming a powerfully economic province which is worthy of the name, the dissertation suggests grasping a few aspects as follows: Set up the idea of exploitation new technology, establish the motive mechanism of technology innovation, establish the mechanism of guarantee the budget of scientific research, establish the mechanism of guarantee scientific personnel, construct the fair competition market environment, allotment technology resources openly in the most possible, make the resources to be allotted and used with high-efficiency, at the same time, relying on the resources advantage of Shaanxi, proceed the technique reform and technique penetration, so as to creates the higher benefit. This dissertation has some creative points: One is using advanced research method, combining compute calculation with new mathematics method, which made the calculation more simple and accurate; The other one is using advanced research train of thoughts, putting Shaanxi province with other regions in the same system, using the same method and the same statistics caliber to handle the datum, which made the calculation results more scientific, more match actual, and can be compared with each other. Application the calculation method in this research can calculate the contribution rates of technology advance of other province conveniently, scientifically, and accurately. So this research has good applied foreground.
