DOver the past decade, the growth in highskilled jobs has largely been limited to Australia's biggest cities. Meanwhile, in rural and regional Australia lowerskilled jobs have been growing fastest. This skills gap is increasing regional differences in income and employment opportunities, despite the promises of technology and infrastructure as solutions to the tyranny of remoteness.Our research finds that jobs, particularly the highly skilled, whitecollar kind, are becoming increasingly collaborative（协作的）. Complex tasks and rapidly changing work environments have increased the need for workers who can collaborate with others to solve problems and who are open to continuous learning. Roles for highly skilled workers are becoming more specialized. This specialization means more collaboration with other specialists and greater space for market positioning.The productive advantages of cities are selfreinforcing. Skilled workers benefit from the opportunity to learn from and add value with other skilled workers. The coordination（协调）costs of this collaborative work are reduced when team members are colocated.Employers also benefit from proximity（接近）to similar firms because there is a larger pool of skilled candidates for new jobs and better access to potential business partners. All these advantages encourage further specialization and productivity gains, with the result that workers and business continue to concentrate around large city centers.The growing skills divide between urban and rural Australia reflects a paradox（悖论）of the digital economy. While digital technology represents a channel for bridging geographic distance, highly skilled workers are increasingly crowding into cities.The latest census（人口普查）data shows no change in the rate of working from home, despite muchimproved digital infrastructure in some areas. In time this may change, perhaps as video confferencing technology improves. However, while better technology might allow regional workers to interact with colleagues and clients in cities. it will also make it easier for citybased professionals to service regional areas.Employment is still growing in regional Australia. But the fact that cities make highly skilled workers more productive means the gap in skilled employment is likely to continue to widen.Attempts to swim against this tide by moving skilled jobs to the country will be expensive. Currently, subsidies（补助金）are needed to attract and retain（保留）highly skilled health professionals to regional communities. Despite this, our analysis of the latest census data shows that the skills gap between regions and cities is still growing.So these subsidies are not translating into sustainable, collaborative communities of highskilled regional workers. Instead, regions need to focus on their strengths, and foster the entrepreneurship that can create new sources of gainful employment.The government's move towards more individualised funding arrangements in the aged care and disability care sectors will increasingly become a resilient（有弹性的） source of income for workers and businesses in regional communities. Demand for aged care services is expected to increase dramatically in the coming decades, such that by 2050 some 3.5 million Australians will require aged care. Adding to this, regional communities are experiencing population ageing at a faster rate than the large capital cities.These are important jobs which should be recognised as such. There will be opportunities for regional businesses to provide the technology and services （ranging from personalised transport to food services）which allow older people and Australians with disability to remain active and healthy.Currently people from the regions who are eager for professional careers typically move to the city to study. In many cases they do not return. Here, technology may be part of the solution. Combining specialised online educational resources with good local support teachers could enable students to access a much wider range of courses from regional areas.Regional communities will also need entrepreneurs（企业家）to develop the future industries and microbusinesses which improve the diversity and resilience of the local economy. However, startups and existing businesses are more likely to survive and expand when there is a supportive entrepreneurship ecosystem, including access to relevant skills development opportunities.1What is the remarkable characteristic of the highskilled job?A.
