The Transformation of Planning Theories: "Paradigm Shift" or "Evolution of Theories"? or Evolution of Theories? A Brief Critique of the Situation of Planning Theories in Iran

The present paper poses the claim that the use of the term ‘paradigm shift’ in relation to the evolution of planning theory in general on one hand, and explaining the theoretical development of planning in Iran on the other, lacks scientific accuracy, and that from this perspective the validity of indigenous theories such as the ‘strategic-structural’ theory must be re-examined. A review of the nature and content of the terms ‘paradigm’ and ‘paradigm shift’, and exploring their possibilities to explain the fundamental changes in planning theory will be first steps in making the case for the above claim. The distinction between ‘theory development’ and ‘paradigm shift’ and addressing the essential differences between the two, has led this research towards developmental methodology, so that in addition to explaining elements of planning theories whose evolutionary course results in a new generation of theories, the underlying and structural conditions of this transition are also examined. Finally, the continuum of transformation of planning theories will be introduced in its general sense in temporal and spatial contexts, based on which the development of a pathology of theorising planning in Iran from the perspective of the internal logics planning theories is made possible. Based on this pathology, the point can be made that rather than paying attention to new, modern planning approaches – such as strategic planning or communication planning – it is necessary to rethink Iran’s planning system within the requirements of its Institutional context, and try to make changes in institutions and institutionalise planning.
