Abstract The topic of the paper is relevant in the field of optimal growth theory and therefore might be seen as an intellectual underpinning for research and practice in the field of transition economies and sustainable long-time development as well. It refers to the papers Panek (2015a, 2018) devoted to asymptotic properties of optimal growth properties in the non-stationary Gale type economy with single and multi-lane turn-pikes in which it was assumed that changing production technology converges in time with certain limits of technology. As far as the postulate of a non-stationary economy (here: technology change) is consistent with real processes, the hypothesis of the existence of some limiting technology may raise controversies and be difficult to verify. In the paper, referring to the above mentioned publications and Panek (2014), a Gale-type economy with changing technology, multi-lane turnpike and time-increasing production efficiency, with no assumption concerning the existence of a limit technology will be examined.

带有多车道生产收费公路的非平稳大风经济中的最佳增长过程

摘要本文的主题与最佳增长理论领域相关，因此可能被视为转型经济和可持续长期发展领域研究与实践的智力基础。它指的是Panek（2015a，2018）的论文，研究了单轨和多轨转弯的非平稳大风型经济中最优增长特性的渐近特性，其中假设变化的生产技术在一定时间内会收敛技术限制。就非平稳经济的假设（此处为：技术变革）与实际过程相一致而言，存在某种限制技术的假设可能会引起争议，并且难以验证。在本文中，参考上述出版物和Panek（2014），
