Problem statement: to investigate changes of public and economic space inextricably connected with transformation of engineering thought which is the basis of the scientific and technological progress both in industry and agriculture. It is necessary to note that development of engineering thought in the agricultural sector involves not only creation of new machinery and equipment designed for processing and development of rural areas. First of all, it involves biotechnologies and gene technologies allowing to bring crop raising and livestock farming to a new evolutionary level. Development of engineering thought and its quality transformation determine both the rate of changes in society and economics and sequence of changes in the technological modes. The approach of this article involves investigation of historical aspects indicating the interrelation between engineering thought evolution and change in technological modes. Results: the technological mode characterizes the specific character of the stage of the scientific and technological progress as well as provides the general idea of the technical level of development of the industrial, agricultural and service and trade sectors of economic sectors. It is commonly known that the technological mode has been dominating in economics for the period from 40 to 60 years, at that, the faster the innovations are implemented (primary those of the technological nature) the higher the rate of the scientific and technological progress is and the higher the quality of social and economic changes is. Conclusion / recommendations: materials contained in the article have allowed to prove once again the fact that change in technological modes and change in scientific and technological progress are of common nature, at that, the key factor of development of social and economic relations is considered by the authors as quintessence of the engineering thought implemented in innovations. This presentation is a continuum of sustainable development of global social and economic relations. © 2014 AENSI PUBLISHER All rights reserved.
