INTRODUCTION

English translation pending.

CORE DEFINITION

Michael Porter introduced the diamond in The Competitive Advantage of Nations. Four determinants explain why firms from a given location succeed internationally: factor conditions, demand conditions, related and supporting industries, and firm strategy, structure, and rivalry. The four reinforce one another, so advantage comes from the system rather than from any single element. Government and chance act as outside influences on the diamond.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Cluster analysis: explain why phone makers gather in Shenzhen and film production in Hollywood. - Location choice: weigh all four determinants before deciding where to build or invest. - Policy audit: find the weakest corner of the diamond and concentrate investment there.

Anchor fast decisions

Advanced factors such as skilled labor and research capacity supply capability; demanding local customers force quality; dense supplier networks cut cost and speed learning; and intense domestic rivalry pushes firms to upgrade. Together these conditions make continuous innovation the local norm, and firms honed at home carry that advantage into foreign markets.
