英文摘要：
A fundamental problem in technological studies is how to measure the evolution of technology. The literature has suggested several approaches to measuring the level of technology (or state-of-the-art) and changes in technology. However, the measurement of technological advances and technological evolution is often a complex and elusive topic in science. The study here starts by establishing a conceptual framework of technological evolution based on the theory of technological parasitism, in broad analogy with biology. Then, the measurement of the evolution of technology is modelled in terms of morphological changes within complex systems considering the interaction between a host technology and its subsystems of technology. The coefficient of evolutionary growth of the model here indicates the grade and type of the evolutionary route of a technology. This coefficient is quantified in real instances using historical data of farm tractor, freight locomotive and electricity generation technology in steam-powered plants and internal-combustion plants. Overall, then, it seems that the approach here is appropriate in grasping the typology of evolution of complex systems of technology and in predicting which technologies are likeliest to evolve rapidly.

中文摘要：
技术研究中的一个基本问题是如何衡量技术的演变。文献中提出了几种衡量技术水平（或最先进水平）和技术变化的方法。然而，衡量技术进步和技术进化在科学上往往是一个复杂而难以捉摸的话题。这里的研究首先以技术寄生理论为基础，在与生物学的广泛类比中，建立了一个技术进化的概念框架。然后，考虑到宿主技术与其技术子系统之间的相互作用，根据复杂系统内的形态变化对技术演化的度量进行建模。此处模型的进化增长系数表示技术进化路线的等级和类型。利用农用拖拉机、货运机车和蒸汽发电厂和内燃机厂的发电技术的历史数据，在实际情况中对该系数进行了量化。因此，总的来说，这里的方法似乎适用于掌握复杂技术系统的进化类型，以及预测哪些技术最有可能快速进化。
