Airports take off as commercial hubs

There is growing concern that an increasing number of China's municipalities are getting in over their heads with airport debt. Critics also argue that an airport construction "bubble" is being created through overinvestment and that some proposed airports are simply not needed.

Critics are right to an extent and the central government is aware of these concerns. CAAC statistics show that nearly three-quarters of China's civil airports lose money and that upwards of 90 percent of smaller regional airports operate at a loss.

These statistics tell only part of the story, however. If not placed in a broader cost-benefit context, they can create apprehensions, which can potentially derail otherwise rational airport investment initiatives.

While it is certainly best for airport accounting balance sheets to show annual revenues at least meeting operating expenditures, this is not the true measure of net benefit of airport investment and ongoing expenditures. Airports, in addition to being enterprises, are valuable public infrastructures that bring considerable benefits to people and businesses in the regions they serve, as well as to the country as a whole.

At the macro level, there is the economic stimulus effect of airport (and other infrastructure) investment that China has used effectively to counter slowdowns in the private sector, creating new jobs, business revenues and, ultimately, additional taxes.

For example, Zhengzhou's new Terminal 2 and its connected multimodal ground traffic center, both currently under construction, are employing nearly 20,000 workers in shifts on a 24/7 basis. When Shanghai Hongqiao built its second runway and new Terminal 2 along with its adjoining 15 billion yuan rail station, similar numbers were employed.

The impact of airports on business development is typically much greater. Soon after investments to expand Zhengzhou International Airport were announced and its 5-sq-km bonded zone created, Foxconn located a manufacturing campus there that employs 240,000 workers assembling Apple's iPhones and other digital devices. Smartphone output from this campus doubled the value of Henan province exports between 2011 and 2012 and has turned Zhengzhou International Airport into China's fastest growing in cargo volumes for each of the past three years.

Building on this success, the 415-sq-km Zhengzhou Airport Economy Zone was established by the State Council in March 2013 to serve as a modern aerotropolis, the name for an airport-centered economic subregion. According to the zone's administrative committee director Zhang Yanming, an additional 14 smartphone manufacturers and suppliers have established bases in the zone, making it the world's largest site for smartphone production. Across all business sectors, 48 major projects in the Zhengzhou airport zone were signed in the past two years with a total investment value exceeding 150 billion yuan.

It is probably unrealistic to think that more than a handful of second- and third-tier municipalities will experience the scale of airport-linked business development that is taking place in Zhengzhou. Even if they are much smaller, though, these broader economic benefits (as well as social benefits that better air connectivity brings) should be considered in the airport investment decision, along with the forecast of annual airport operating costs and revenues.

Still troublesome is the heavy debt burdens many municipalities are amassing to construct airports where significant central government subsidies are not available. It is therefore encouraging to see that the State Council is developing policies permitting private-sector investment in municipal airports through public-private partnerships.

It is similarly encouraging that China's governments at all levels are fostering aerotropolis development around airports through favorable land-supply policies, bonded and free trade zones, tax incentives, and surface transportation infrastructure provision. Resulting business investment will not only boost municipal and provincial economies, but also generate additional passengers and cargo for airports, thereby improving their longer-term financial viability.
