Moreover, the renminbi has come under downward pressure, owing partly to economic recovery in the United States, which has fuelled capital outflows. Given huge declines in industrial profit growth (from 12.2 per cent in 2013 to 3.3 per cent last year) and in local-government revenues from land sales (which fell by 37 per cent in 2014), there is considerable anxiety that today's deflationary cycle could trigger corporate and local-government debt crises.
China hopes to secure its long-term economic development by shifting from a state-directed to a market-led economy. But the process has created significant discrepancies in economic performance, with state-owned enterprises (SOEs) performing significantly worse than their private-sector counterparts, despite having better access to credit. And there is a widening disparity between real-estate prices in China's thriving first- and second-tier cities and its lagging third- and fourth-tier cities (though higher household incomes in the former make housing there more affordable).
The authorities' task now is to determine how to support continued growth on the better performing track (the private sector and the first- and second-tier cities), while eliminating overcapacity and boosting productivity on the weaker track (SOEs and third- and fourth-tier cities). To succeed, they must address the fallout of the previous approach, which, by providing more money and preferential policies to the lagging track, ended up fuelling overcapacity and unsustainable local debts.
In other words, China must confront the sunk costs of bad local-planning decisions. Instead of continuing to hope that bureaucratic intervention can repair flawed projects, officials should take a market-based approach, allowing losses to be allocated through the bankruptcy process, thereby enabling all stakeholders to move on to more productive activities.
The Chinese economy's dual-track structure also presents unique challenges for macro-financial management. As the fast-growing sectors absorb an increasing amount of resources, a shift toward more market-oriented interest rates is needed to ensure efficient allocation. Meanwhile, the slow-growing sectors risk falling into a "balance-sheet recession", with highly indebted SOEs and local governments becoming so focused on paying down their debts that they stop investing in needed infrastructure, even when interest rates fall. As a result, conventional monetary and macro-prudential policies are caught between competing demands for credit, with one track needing to support productive growth and the other attempting to buy time for restructuring.
The People's Bank of China (PBOC) has attempted to confront this dilemma by differentiating reserve requirements according to sector or type of financial institution. The results have not been encouraging.
For example, when the PBOC cut its benchmark interest rate last November, in order to help reduce private-sector borrowing costs, it triggered a speculative stock-market boom. Following January's disappointing macroeconomic data, the PBOC acted again, by lowering the reserve ratio for banks by 50 basis points, with additional cuts for banks focused on small and medium-size enterprises (50 basis points) and for the Agricultural Development Bank of China (400 basis points). Despite these efforts, neither track seems satisfied that their credit demands are being met.
Efforts to address these structural challenges are being frustrated not just by institutional barriers, but also by entrenched official corruption. The problem is that anti-corruption measures, despite enjoying broad public support, undermine bureaucratic effectiveness in the short term - a significant issue in a critical reform year, especially given slowing growth.
Institutional reforms aimed at combating corruption, reducing overcapacity and dealing with unsustainable local debts will generate long-term dividends and sustainable payoffs. But short-term stimulus measures, such as tax cuts and higher fiscal deficits, will be needed to minimise growth disruptions. This would mean reversing the recent decline in the government Budget deficit, which narrowed to 1.8 per cent last year, from two per cent of gross domestic product (GDP) in 2013.
The transition from a dual-track economy to a market-based economy will not be easy. The Chinese economy is clearly in urgent need of repair. But the news is not all bad: a substantial portion of the economy continues to expand, underpinning much higher overall growth rates than in most other economies. Moreover, despite some concerns about capital outflows, China's consolidated net foreign-asset position, which stands at $1.7 trillion (17.6 per cent of GDP), remains sufficient to sustain China through this tough transition.
China's leaders recognise the long-term imperative of serious institutional reform, even as concerns about slowing growth heighten the temptation to embrace short-term fixes. The authorities are taking strong action to curb pollution, improve energy efficiency, implement pension reform and expand access to healthcare and low-cost housing.
More immediately, China's leadership is committed to excising the cancer of corruption. The key, as with any critical surgery, is to ensure that the necessary life-support systems are in place. In China's case, that means maintaining adequate liquidity.
In the end, sustainable development will require that China's two economic tracks merge. With the right approach, relatively stable and rapid growth can be maintained throughout the reform process. Avoiding a hard landing would be good not only for China; it would ensure much-needed growth and stability for the global economy.
