Customers love them, because private transportation has never been this convenient, efficient, and accessible.

Taxi drivers oppose them, because their rapid expansion and popularity have resulted in conspicuous customer drain for the traditional taxi market.

Government regulators find them concerning, because they do raise questions about safety, fairness and legitimacy. Not to mention, they do not fit into any existing regulatory framework.

Which is why mobile app-based ride-sharing services, such as Uber and various indigenous cousins, have found themselves in a largely undefined gray zone.

In Beijing, for instance, where Uber and its Chinese look-alikes have grown phenomenally, contracted drivers have been operating in stealth mode for fear of heavy fines.

But despite all the complaints, resistance, even bans in some places, Uber and similar services have continued mushrooming and prospering.

The popularity of app-based ride-sharing has a lot to do with dissatisfaction with taxi services in the pre-Uber days.

In China, however, it goes far beyond a more pleasant user experience. Multiple recent surveys have highlighted the new services' role as job creator.

Uber and its local peers have reportedly become an important income provider for workers displaced in the process of reducing industrial overcapacity. One survey even reported that being a contracted driver for Uber or a similar ride-sharing service provider is the only source of income for more than half of the workers laid off recently in the coal and steel industries.

Given the obvious loopholes in operation and management of such services, especially with regard to driver certification, security guarantees and taxation, it is certainly necessary to regulate the industry.

But an all-win, all-happy solution is difficult to arrive at precisely because such services are too new, too complicated for regulators.

The authorities made a daring, respectable move on Thursday by giving app-based ride-sharing legal status and introducing standards for the new sector.

Yet although it has been reviewed and revised repeatedly based on feedback from the public, the regulatory regime unveiled still needs further research and clarification.

The stipulations show plenty of thought has been given to key problems surrounding the brand-new business model. But they do display the inclination to include the new services into regulators' modus operandi, and render them another part of the traditional taxi service market.

Such an inclination may undermine the otherwise promising prospects of something the public clearly wants.
