In the German sustainability strategy, two indicators are used to measure the economic performance and competitiveness of the economy. The indicator described here refers to the level of investment in production goods in relation to gross domestic product. The indicator, also known as the investment ratio, includes the acquisition of all fixed assets by all resident producers minus the fixed assets sold. Fixed assets are produced assets that are intended to be used repeatedly or continuously in the production process for more than one year, such as buildings, machinery, vehicles or software. Gross fixed capital formation is determined within the framework of national accounts (NA), the compilation of which follows harmonized European rules. The data for Germany come from the Federal Statistical Office. The data for the European comparison come from the Austrian Federal Economic Chamber.

There is no precise target value for this indicator in the German sustainability strategy. According to the indicator report, the German government is aiming for "appropriate development". For the calculation here, therefore, the mean value of the five countries in Europe that have the highest values is taken. The resulting target value is 29.72.

For indicators without a set baseline value, 2030Watch uses the SDSN method to orient itself to the second-worst value in the given country comparison.

This is an official indicator of the German Sustainability Strategy.
