Investors, good afternoon. I am CFO of New World, Edward Lau. I will first present our Group's 2021 FY first half results. Please turn to Page eight. Through active management in 2021 FY, our results were better than expectation. We believe the worst time has been over.
Our revenue was HKD 35.6 billion, up 10% year-over-year. Mainly came from property development, property investment, and core assets of NWS. Profit attributable to shareholders, HKD 1 billion. Comparing with the same period of last year, it is stable. COVID-19 was volatile, but we are stringently controlling our cost and expenses, so our recurrent administrative expenses was down 12% year-over-year. Comparing with FY 2020, at that time we were down 8%, so we had made improvements. Through distributing stable interim dividend and also in December 2020, we bought back 10.4 million shares of NWD. We actually paid back to investors support. In Hong Kong, in the first half of the year, property contracted sales reached HKD 26.3 billion. It exceeded our full year target of HKD 20 billion.
In mainland China, in first half fiscal year, property contracted sales was RMB 11.2 billion, slightly higher than our half year results. For the whole year, we want to achieve mid to high single-digit growth. From FY 2021 till now, we successfully sold non-core assets of HKD 12.8 billion, including HKD 3.2 billion of bus service, RMB 1.3 billion of Wuhan office properties, HKD 6.5 billion sewage treatment business, and RMB 400 million Northern China residential property management business and others.

You can see that our property development revenue was up 7%, mainly from Ningbo New World Plaza land. More sales revenue will be booked in second half of 2021.
In Hong Kong, about HKD 4 billion-5 billion main revenue was from Artisan Garden and Atrium House. In the whole year FY 2021, Hong Kong sales revenue will reach HKD 7 billion-8 billion. Because of a time difference, in the second half, there is more revenue than first half in Hong Kong. In mainland China, revenue booked for the whole year is more or less the same as last year. It mainly came from Prince Bay, Guangzhou project, and Shenyang New World Garden. Segment profit was down 40%. This is because the booked GBA project gross profit margin was slightly lower. For the group, our consolidated gross profit margin was 32%, which is healthy. For GBA project, gross profit margin was 66%, which is strong. For Pavilia Farm, our contract sales exceeded HKD 23 billion.
In only six weeks, we already surpassed the HKD 20 billion sales target for FY 2021. Now we are applying for pre-sale consent for phase III. This project had broken our record in the past 23 years in Hong Kong. It is known as the New Ticket King by the media. We have incorporated the post-pandemic concept into our building and design. In order to avoid gathering of people, The Pavilia Farm is the first project in Hong Kong applying blockchain technology in PropTech. We encourage buyers to apply in a paperless way. We greatly shortened application processing time. Those who cannot get slots in the first price list will automatically be moved into the next price list. This enhances our competitive advantage. 888 Lai Chi Kok Road.

We have attracted more than 3 million views. For our KLUB 11 member scheme, we successfully expanded the ecology, and we attracted members to do repeat purchase. For K11 members spending on an HoH basis was up 110%. In Mainland China, K11 successfully seized the opportunities from consumption upgrade and domestic circulation.

This can help lower our future financing cost. ESG. In the first half, we are still the international leader in ESG integration. We adopted further climate actions in order to mitigate the climate crisis globally. Among main international ESG rating companies, we got good recognition.
For example, in 2019, we got the highest rating from GRESB. In 2020, we were rated globally number one in terms of climate resilience. We'll continue to promote our performance in 2030 vision. Our progress is in line with expectation. In the first half, we had already reduced carbon emission by 26%. In FY 2020, that was 22%. We are above that. As a forward-looking company, we are strengthening our governance to promote climate action. All ESG matters, especially climate risk, are supervised by the board. We support TCFD.

We are the third company in Asia, following Swire Properties and also City Developments Limited. For the coming 10 years, we have already formulated renewable energy blueprints. Through self-production, electricity purchase agreements, and renewable energy certificates, we will enhance our utilization of renewable energy.

That's all about our results. Now let me pass the floor back to Dr. Cheng. Right.
Regarding New World Development, in terms of technology ecosystem, well, we have some very unique growth potentials.
Our ecosystem covers 17 businesses with 400 odd working partners, covering all elements of customers' life. This can enhance our inner circulation. For our ecosystem, the system continues to expand and rise in value. Through high tech, for example, our customer relationship management, CRM, K Dollar reward system. For 40 million members, we do customer data analysis and precise marketing in order to enhance repeat purchase. This is only done by us. We have been doing that for a few years. Now this ecosystem is already materializing. From enhancing customer loyalty, we hope to increase cross-selling. If we look at the benchmark in 2020, the relative growth was 17x in cross-selling. This is also CAGR. This is in the form of CAGR. Talking about our ecosystem, we have 14 million customers, including retail, healthcare, housing, medical service and so on.
For our ecosystem, we have both hardware and software for cross-selling and inner circulation. We have achieved a very high benchmark. Together with internet companies and banks and other strategic partners, we will attract public domain traffic to our private domain. Comparing with other people, we are more outstanding because of our CRM and big data analytics technology, which have built a full and complete ecosystem covering all areas of life. With our K Dollar reward scheme and O2O platform, including K11 GO in China, our online platform, and K11 app in Hong Kong, our customers and members of the public are given all-round high-quality spending opportunities and personalized service. We have been doing this for a few years. We are deepening our service. We have four tech pillars to improve customer experience. First, we use AI and big data to understand customers' preference to drive repeat purchase.
Step one, with CRM and big data, our internal data analytic team gather huge amount of information from the ecology to understand customer preference. Step two, we use AI data to analyze and build customer database. Step three, through K11 GO and K11 app, we enhance O2O experience. We do precise recommendation and also live streaming product to stimulate sales. K Dollar, KPOS are unique for us. This is step four. We want to drive instant earn and burn. For K Dollar, people said that it is the same as other spending vouchers. No, it's not. K Dollars can be regarded as currency. Comparing with other reward schemes, K Dollar has two competitive advantages. Number one, there is no earning limit. Number two, there is no burning condition. It is used as currency. It is very easy to use. K Dollar achieved integration of platform and currency.
It enhanced the cross-selling opportunities between business units in the ecosystem. K Dollar can increase the opportunity of repeat purchase or recurring spending. We have done a survey. After the launch of K Dollar, for each K Dollar spending, it can generate four to five times of spending multiples for the group. Let me give an example. For The Pavilia Farm, buyers have joined New World CLUB, they get K Dollar rewards. In FY 2021, we plan to give out HKD 100 million K Dollar. In the coming three fiscal years, we will issue HKD 300 million K Dollars. Our group works with Chow Tai Fook Jewellery, every year we will issue HKD 30 million of K Dollar. Two years later, we plan to issue a few times more. Now, we talked about cross-selling between insurance and retail.
If we look at 2017 to 2019, comparing with 2020, that is the three-year average comparing with 2020, cross-selling amount has risen 17x . If you use 2020 as the benchmark, the relative growth was four times. If you look at overlapping members in the first year to the fifth year, well, their CAGR was 35%. They like you more with more overlapping. There will be more cross-selling, and so spending will get higher and higher. In terms of technology, IoT automation, we are doing a good job. First, residential. Among Hong Kong property developers, we are the first to offer a smart home technology, especially in mainland China, among Hong Kong enterprises. In China, we have launched new IoT system offering personalized and comfortable experience.
We work with IoT companies, we offer high-quality smart home technology and most advanced design and building options. In the future, we will launch 13,000 units equipped with smart design in China. For offices, we use robotic technology in cleansing and sanitization, and also in the F&B business. This can enhance efficiency and hygiene level.
