Updated at 6.28pm: Secretary for Home Affairs Patrick Ho Chi-ping said on Monday Hong Kong and mainland cities were developing an index to measure creativity. Speaking at the ministers' meeting of the Asia Cultural Co-operation Forum 2004, Dr Ho said: 'There is clearly a pressing need for developing a set of scientific tools to measure the creativity of our cities. Only by doing so could we disentangle the effects of various factors and draw parallels for comparison with our neighbouring cities.' 'Through a common creativity agenda, we believe that we can build up our creative societies and strengthen our creative alliance,' he said. Dr Ho said studies of national competitiveness - such as the World Economic Forum Growth Competitiveness Index and the Heritage Foundation Index of Economic Freedom - failed to adequately measure features characterising a creative economy. 'The baseline studies that have been completed so far primarily zero in on measuring the gross domestic products contribution of creative industries. While useful, this only surveys the downstream aspect of a creative economy,' Dr Ho said. 'This calls for a scientific survey of the upstream aspects of a society - the values, institutions, practices and customs - that attracts creative talents and creative enterprises to come to our cities, make home there and develop their creative business there,' he said. The creativity index will consist of: creative outputs and outcomes; human capital; structural and institutional capital; social capital; and cultural capital, explained Dr Ho. The index would also take into account western and Asian influences, Dr Ho added. In Hong Kong, creative industries accounted for slightly less than four per cent of GDP in 2001.
