766 ITU‐T's Technical Reports and Specifications 6.3.3 D3 Productivity The ICT impact on D3 Productivity would be evaluated in nine categories: capital investment (D3.1), formal/informal employment (D3.2), inflation (D3.3), trade (D3.4), savings (D3.5), export/import (D3.6), household income/consumption (D3.7), innovation (D3.8), and economic sustainability (D3.9). Economy is the driving engine of human society. Therefore, it is necessary to investigate whether or not SSC helps to prime the pump of the local economy. Meanwhile, innovation weighs increasingly in the economy. As high tech plays a pivotal role in SSC, it is valuable to find out the local competence of innovation. D3.1 Capital investment This part is about the capital investment when building SSC. D3.2 Employment This part is about the formal or informal employment in a city. D3.3 Inflation The indicator of inflation reflects the currency devaluation and price rise. D3.4 Trade This part is about the e‐commerce transaction in SSC. D3.5 Savings This part is about the average household savings in SSC. D3.6 Export/import This part is about the export/import at the city level. D3.7 Household income/consumption This part is about the average household income/consumption in SSC. D3.8 Innovation This part assesses the city’s ability of innovation through multiple perspectives. It would indicate whether it is an innovation city or innovative city. Innovative city refers to cities that can adjust to changes quickly and play as a regional lead. D3.9 Knowledge economy This part studies whether or not SSC is pumping the economy. Because of the fast growth and drastic changes of technology innovation as well as its close effect on the economy, industry, science and society, economic sustainability must face challenges from all these impacts. 6.3.4 D4 Quality of life The ICT impact on D4 Quality of life in SSC would be sampled mainly in the following four sectors: education (D4.1), health (D4.2), safety/security public place (D4.3), convenience and comfort (D4.4). D4 will find out if ICT is helping people get a better life.
