150、 is a significantly positive correlation between the Computing Index and the GDP/digital economy.In the linear regression goodness-of-fit test,the model has a better fit when the Computing Index is the independent variable and the digital economy and GDP are the dependent variables,as opposed to hav

151、ing the Computing Index as the dependent variable and the latter two as the independent variables.Therefore,using the Computing Index to predict the digital economy and GDP better fits the reality than using the latter two to predict the Computing Index.As mentioned above,the increase in the Global

152、Computing Index mainly depends on the computing capacity and application level of emerging technologies.That is,while computing power investment provides a basic guarantee for the development of emerging technology applications,it is also further promoted by the demand from emerging technology appli

153、cations,thus having a multiplying effect on overall economic growth.On average,for every 1-point increase in the Computing Index of the 15 key countries,the national digital economy and GDP will increase by 3.5 and 1.8,respectively,and that trend is expected to continue through 2025.After further re

154、gression analysis on the Computing Index and GDP of countries at different tiers,it was found that the influence of a country s Computing Index on GDP is different based on the point range.If m refers to the impact of every 1-point increase when the Computing Index is below 40 points,then the impact

155、 will increase to 1.5m or 3m when the index is more than 40 points or 60 points,respectively,which means more significant economic growth.2021-2022 Global Computing IndexAssessment Report2728Social Value ofComputing PowerIn recent years,emerging infectious diseases such as the novel coronavirus(COVI

173、sive computing and storage tasks.The boom in AI technologies and the popularity of accelerated computing applications continue to drive the exponential growth in processing power consumption(270/280W+for CPUs and 500W+for GPUs),which has become a serious bottleneck for efficient data center system d

174、esign.Challenges such as reducing the carbon footprint and greenhouse gas emissions of data centers,integrating energy conservation into daily operations,reducing operational expenses,and lowering PUE are becoming key considerations for solution providers and data center owners.From a green perspect

175、ive，to build green data centers,a variety of initiatives are being taken to reduce carbon emissions from data centers,including adopting liquid cooling for higher cooling efficiency,introducing new energy sources such as wind and solar energy,using AI/ML technologies to upgrade operation&maintenance

176、 management processes,and adopting new chip architectures to achieve higher computing power output per unit of power consumption.The worlds leading cloud computing players are embracing more new energy.AWS has built solar powered and wind powered plants to power its data centers in Spain,Scotland,Sw

178、 upgrades to data center infrastructure management and adaptive control systems by deploying liquid cooling,AI/ML,and other operational technologies,with its global annual average PUE lowering to 1.5.There are two types of liquid cooling:direct liquid cooling(DLC)and immersion cooling(IC).Cold plate

179、 liquid cooling is the primary form of DLC solution,which is a direct upgrade to existing rack systems for more efficient cooling,especially for high computing power/high power processors.IC has a higher cooling efficiency than the cold plate solution,but it costs more.Of all liquid cooling solution

180、 options,IDC believes that DLC solutions will be more widely used in the data centers,especially for enterprise users,thanks to cost-effectiveness and scalability based on existing cooling systems and data center infrastructure.For IC,given factors such as the redesign/reconfiguration of data center

181、 systems,racks,floors,and other facilities,as well as costs associated with data center construction and operation(CAPEX/OPEX),such solutions will be more suitable for enterprises such as cloud service providers that are already running large-scale systems and data centers.2021-2022 Global Computing

212、hodology2021-2022 Global Computing IndexAssessment Report37The model for evaluating the Global Computing Index consists of four Level-1 indicators and 20 Level-2 indicators.The model is used to evaluate the development level of the computing power and the potential for future development of the 15 k

213、ey countries around the world.The four Level-1 indicators include computing capacity,computing efficiency,application level,and infrastructure support.The indicators are independent of each other,but are also closely correlated.The computing capacity reflects the theoretical maximum computing power

214、of a country.It is the core of the entire evaluation system and occupies the highest weight among the four indicators.The computing efficiency reflects the current level of computing power utilization of the country.Some countries have higher utilization in cloud computing and virtualization,and the
