Supporting ecological innovations and economic activities which lead to environmental protection is one of the important challenges to decision-makers. The above is related to the problem of specification of mechanisms resulting in introducing ecological innovations to the economy. The original vision of the economic evolution determined by innovation was firstly presented by Joseph Schumpeter who identified essential innovative changes as well as indicated different mechanisms governing the economic evolution. The aim of the paper is to suggest a cohesive topological approach maintained in the stream of Schumpeter’s thought, to study changes in the economy, which result in the elimination of at least one harmful commodity or technology from the market, by incorporating Hurwicz apparatus in a suitably modified competitive economy. Qualitative properties of mechanisms which can occur within the economic evolution are also analyzed.

This research is inspired by Schumpeter’s theory of economic development and aims at analysing the outcomes of innovative and non-innovative changes implemented within economic evolution. A multiplicity of outcomes of economic processes leads to complexity of the structure of economic evolution. In order to examine innovative processes, the role of the circular flow, i.e. a form of the economy, which for Schumpeter was both the starting and ending points in the analysis of economic development, should be taken into account. In this context, we determine a simple model of economic evolution in line with Schumpeter’s theory, using Hurwicz’s concept of the adjustment process. This allows us to examine an impact of accessed information on diversification of economic processes. It should be added that in the model presented, non-innovative changes also play important roles, which is coherent with Schumpeter’s theory. As a result, we prove, under some initial conditions coming from the mainstream of the Schumpeter’s thought, that the economy under study can evolve in the direction of equilibrium and take a form of circular flow.

Let a private ownership economy with a financial market be given. In this economy, innovations in Schumpeter's sense of the term can be modeled by the use of the Arrow and Debreu topological apparatus. This set-up reveals the impact of the relationship between the financial and the real markets in the economy on innovation.The paper distinguishes and models innovations and different types of innovative mechanisms revealed within Schumpeterian evolution. Following Hurwicz's approach to modeling economic mechanisms, the main results take the form of mathematical theorems interpreted in the language of economics.
