This year’s version of the GCTCI model is in many ways a continuation of the structure and methodology used in previous years. At the same time, there are several important new features to the GCTCI 2020, as efforts have been made to improve its architecture, the variables/data used, and the city coverage.
The most significant changes include:
1. A greater number of cities covered: 155 cities, up from 114 cities last year
2. The introduction of more business- and impact-oriented indicators related to such issues as ease of doing business, foreign direct investment, and patent applications
3. A higher share of values that are observed at the level of cities, rather than at regional or national levels
The five pillars of last year’s GCTCI model have been largely retained this year. The first four pillars are completely unchanged and continue to follow the same logic as the input-related pillars of the GTCI model by analysing how cities (1) Enable, (2) Attract, (3) Grow, and (4) Retain talent. The one slight modification to the model concerns the fifth pillar that has been renamed Global Knowledge Skills this year in order to emphasise a focus on talent impact as well as the degree of internationalisation of cities. In addition, this change in terminology is in keeping with the GTCI model.
