An article of dr Piotr Marciniak: “Building Institutional Effectiveness of Public law Chambers of Commerce: an Introduction to the Sectoral Model” was recently published by Krytyka Prawa (17) nr 3/2025, pp. 212–235. This is the first description of the Sectoral Model of Chambers of Commerce in English.

Abstract:
Chambers of commerce are business environment organizations associating enterprises. They operate on the basis of very different models and regulatory frameworks around the world. They differ in particular in terms of their establishment, principles of membership and financing, tasks, social perception and political position. As a result, in some countries we find powerful, public law chambers associating all enterprises by law, and in others – hundreds of small private law organizations associating several dozen companies on a voluntary basis based on regional or industry criteria. As a result, their potential is extremely different.
In addition to their various tasks, chambers of commerce can also be a partner in the implementation of the processes of decentralization of public tasks in countries with a developed market economy. And play an important role in increasing institutional efficiency in the sphere of the economy. However, the scope and potential effectiveness of this process depends not only on political decisions expressed in the adoption of appropriate legal acts, but also on the model structure and competences of the chambers. Effective support for business and public institutions requires solutions that correspond to the requirements of the increasingly complex and specialized economy of the 21st century.
The subject of the study is to discuss the basic features of the sectoral model and to indicate its advantages over the continental model in the process of decentralization of public tasks (including administrative competences of an authoritarian nature). The analysis was prepared taking into account the postulates of the new institutional economy. The global and domestic economy is undergoing dynamic changes, to which both public institutions and chambers must adapt accordingly.
