Abstract:
First, the terms production, efficiency and effectiveness are defined, and the key determinants of productivity and fundamental elements of production theory are presented. Characteristics such as marginal products, scalability, the relationship between production and growth, and the various types of productivity shed light on how efficiently production factors are used from different perspectives. They help to better understand the performance of an economic system. Building on this, the productivity development of the construction industry and non-construction industries is presented and classified using three economic indicators. These include gross value added and the labour productivity calculated from it, the production index and multifactor productivity. The factors influencing productivity are then analysed. The aim is to identify the causes of the respective economic developments in the construction industry and selected non-construction sectors. The effects of the influencing factors are examined equally in the course of the analysis. This is followed by a comparison between them with the aim of identifying success factors in non-construction industries that have the potential to positively influence economic development in the construction industry. Against the backdrop of the productivity analysis and the industry comparison, scenarios are then developed and presented to show how changes in individual or multiple production factors and influencing factors can affect economic development. Furthermore, the effects of an increase in the degree of intermediate consumption in the form of prefabricated parts or modular construction are examined. One focus here is on evaluating cost efficiency, i.e. the relationship between the resources used and the economic output achieved. In addition, the extent to which a long-term equilibrium, known as steady state, can be achieved under different models is analysed. The thesis concludes with an evaluation of the scenarios and a final outlook.
