Contributions of the home, business, and new markets to service revenue increased by 4.3 percentage points to 35.7%, showing a further optimized revenue structure. Drawing on the advantage of our business scale, we continue to implement our value-oriented operating practices in greater depth. We achieved significant results in the comprehensive and integrated developments of CHBN markets. We achieved all-round customer growth. Mobile customers, household broadband customers, and corporate customers recorded net additions of 14.97 million, 25.88 million, and 4.99 million respectively. IoT smart connections recorded a net additions of 175 million, demonstrating a solid industry-leading position. We effectively enhanced customer value with a rebound in mobile ARPU, which increased by 3%. Household broadband blended ARPU increased by 5.6% year-on-year. We accelerated expansions and extensions of information services and our innovative business gained strong momentum. Digital transformation revenue increased by 26.3% year-on-year to reach CNY 159.4 billion, accounting for 21.2% of service revenue, up by 3.1 percentage points. It contributed nearly 60% of the growth of service revenue to become our largest revenue growth driver. The second curve of growth with digital transformation revenue as the major component is leading us to explore a broader market in the blue ocean of information services. Among which, revenue from smart home value-added business reached CNY 20.7 billion, up 33.1% year-on-year. Its contribution to the home market revenue went up by 1.9 percentage points over 2020.

Among which, An-Caiyun customers from the customer and home markets exceed 130 million. For industry cloud, public cloud ranked in the top 7 in the industry, and private cloud ranked fifth. We systematically optimized the layout of our new information infrastructure, with focuses on 5G, Computing Force Network, and smart middle platforms. For 5G, we fully implemented our 5G+ plan by advancing 5G network co-construction and sharing with CBN. We're able to leverage combined advantages of 2.6 GHz and 4.9 GHz capacity and 700 MHz coverage to create synergy from multi-frequency network and enable efficient deployment. We put in use a cumulative more than 730,000 5G base stations and basically achieved continuous 5G network coverage across urban districts, counties, towns, and villages. With number of 5G network customers exceeding 200 million, we maintained our industry-leading position. For Computing Force Network, we will construct a ubiquitous and integrated CFN to provide plug-and-play, ready-to-use computing force services. Efforts will be made to provide efficient integrations of computing force in physical space, logical space, and heterogeneous space. By integrating computing with network, we will build a brain of computing network and enable an integrated scheduling and orchestration. We'll gradually promote computing force as an essential service similar to water and electricity serving the whole society. For the supply of computing force, we responded to the national strategy of channeling more computing resources from the eastern areas to the western areas by establishing our 4+3+X data centers with a total of 407,000 IDC cabinets available for external use, representing a net addition of 47,000. We continue to build up our cloud infrastructure and improve the layout of N+31+X mobile cloud infrastructure. For the computing force services, we actively explored business integration and innovation. During the Beijing Winter Olympics, we applied CFN and integrated the metaverse concept to create digital intelligent sports personas, XR broadcasting studios, AR snow towns, and other snow-themed applications to promote winter sports. On Smart Middle Platform, we established an open and sharing Smart Middle Platform offering modular and ready-to-deploy capability services. In 2021, we centralized 325 common capabilities, and these capabilities were deployed more than 8.1 billion times per month on average, empowering digitalization and intelligence in more than 2,000 internal and external scenarios. Our Wutong big data service cumulatively processed more than 600 petabytes of data, a scale that puts us at the forefront of the industry. We made great efforts to foster technological innovation and transformation. We further increased R&D investments and continued to optimize our integrated layers of four technological innovation system, effectively stimulating innovation and vitality and creating new drivers for our high-quality development.

For strategic cooperation, we proactively formed and deepened strategic partnerships with local governments, enterprises, and public institutions, collaborating on the promotions of digital industry and digitalizations of industries. For ecosystem construction, we made concerted efforts to help upgrade the industry chain through capital investments and funding and further expanded the information service ecosystem. We also followed the guiding directions of digital-intelligent transformation and formed a Circle of Relatives. On the 5th of January 2022, the company's A-shares were officially listed on the main board of the Shanghai Stock Exchange, making us the first red chip stock listed on the main board of the A-share market and marking another milestone in our history of development. We have introduced 19 diverse and high-quality strategic investors, including national-level investment platforms, well-known leading enterprises in various fields, and long-term financial investors such as the National Social Security Fund.

Together with the interim dividend of HKD 1.63 per share already paid, total dividend for the 2021 financial year amounted to HKD 4.06 per share, an increase of 23.4% year-on-year. To create higher returns for our shareholders and share the fruits of our operating gains, after giving full consideration to the company's profitability, cash flow generation, and future development needs, in the 3-year period from 2021, the profit to be distributed in cash for each year will gradually increase to 70% or above of the profit attributable to equity shareholders of the company for that year. The company will strive to create more value for shareholders. With the advancements of a new wave of technological revolution and industry transformation, information technology is increasingly becoming the fiber of every aspect and process of the economy, society, and people's livelihoods. The pace at which the digital economy is developing and the breadth and depth of its impacts are at previously unseen levels. Connectivity, computing force, and ability have gradually become the pillars that support the digital intelligent transformation of society. The information and communication sector, as a key driver of digital economic development, will have ample room for growth. It is estimated that by 2025, the revenue of China's information services industry will exceed CNY 20 trillion, with a CAGR of 14.4%, while computing network market size will exceed CNY 1 trillion, with a CAGR of 25%. Faced with the new development trend, we reiterate our development goal of becoming a world-class information services and sci-tech innovation enterprise. We spare no efforts in building a new information service system of connectivity, computing force, and ability based on 5G, Computing Force Network, and smart middle platforms in order to create a new model of value growth. 2022 is a critical transitional year in the 14th Five-Year Plan, building on the past and preparing for the future. We will embrace new phase of development, fully, accurately, and comprehensively implement the new principles of development, and devote ourselves to the new paradigm to promote high quality of development. We will pursue stable progress while forging ahead with a steadfast focus on innovation-driven development. At the same time, we still consider efforts to further towards the new positions of becoming a world-class information services and sci-tech innovation enterprise and implement our new strategy of building world-class and powerhouse. We drive new infrastructure, integrate new elements, and instigate new growth momentum, striving to achieve favorable growth in service revenue and net profit, and consistently creating greater value for shareholders and customers.
