The Rise of Private Property in China. Part 1
«The Rise of Wealth-Income Ratios and Private Property in China»
In this Part, we present our main results on the evolution of aggregate wealth from 1978 to 2015.
The evolution of wealth-income ratios and public property
We start with the general evolution of the level and structure of national wealth. The Chinese national wealth-national income ratio has increased substantially in recent decades, from about 350% in 1978 to 500% in 1993 and over 700% in 2015, with important changes in the composition of wealth.
Agricultural land used to account for almost half of total wealth in 1978, and now accounts for less than a tenth. In contrast, housing and other domestic capital (buildings, equipment, machinery, patents, etc., used by corporations, public administrations, and households) increased enormously, both in shares and in levels. Net foreign assets have become a significant addition to China’s national wealth since the mid-2000s.
The most spectacular evolution involves the division of national wealth into private and public wealth.
Private wealth was relatively small in 1978 (about 100% of national income), and now represents over 450% of national income. Public wealth, by contrast, has remained roughly stable around 250% of national income. As a result, while in 1978 about 70% of national wealth was public and 30% private, in 2015 the proportion are reversed: 30% of national wealth is public and 70% private.
China used to be a communist country and is now a mixed economy.
The privatization process was particularly extensive for housing: 95% of the housing stock is now privately owned, against 50% in 1978.
The situation is different for other domestic capital: the public share has declined, but it is still about 50%. If we look more specifically at the ownership of domestic equities (traded and non-traded), we find that private ownership was negligible in 1978 (about 5%), and reaches about 30% in 2015. This is obviously a large rise, but it means that the government remains the owner of about 60% of Chinese domestic equities (while foreigners own the remaining 10%). Interestingly, the fraction of Chinese equities that is publicly owned dropped substantially until 2006, but seems to have stabilized-or even increased somewhat-since 2007.
When comparing China to other countries, we find that the private wealth-national income ratio in China is now close to Western levels: 450-500% in China in 2015, vs. 500% in the United States and 550-600% in Britain and France.
The major difference is that public wealth has become very small-or even negative, with public debt exceeding public assets-in Western countries, while it has remained substantial in China.
Net public wealth used to be positive and substantial in all Western countries in 1978; the government owned between 15% and 25% of national wealth in the United States, Japan, France, Germany and Britain in the mid-1970s. This mixed economy regime resulted from a combination of low public debt (following post-World War 2 debt restructuring and inflation) and a large public sector, including in some cases government ownership of large companies in banking and manufacturing (such as in France until the mid-1980s). The share of public property in China today is somewhat larger than-but by no means incomparable to-what it was in the West from the 1950s to the 1980s. (We present two alternative series on the public share in China’s national wealth, depending on what fraction of agricultural land is assigned to the government and the private sector. This makes a significant difference at the beginning of the period (given the importance of agricultural land in 1978), but has relatively little effect in 2015 (see Figure 7d). In any case, the general trend and orders of magnitudes are not affected.)
If anything, the public share in China’s mixed economy seems to have increased since the 2008 financial crises, while it has dropped in rich countries-net public wealth is now slightly negative in the United States, Japan and Great Britain, and only slightly positive in Germany and France.
The structure of national property has large implications for economic development. The size of public property affects the State’s ability to conduct industrial and regional development policy (sometime in an efficient way, sometime less so). It also has potentially large fiscal consequences: governments with negative net public wealth typically must pay large interest payments before they can finance public spending and welfare transfers, while those with large positive net public wealth can benefit from substantial capital income and finance more spending than what they levy in taxes. To a large extent this is an under-studied subject, partly because of the lack of adequate data collection on national balance sheets. Looking forward, it would be valuable to collect more data to be able to compare the evolution of China’s property structure not only with Western countries but also with other emerging economies.
It is interesting to compare the evolution of the public share in national wealth in China and in an oil-rich country such as Norway with a large sovereign wealth fund. Both countries have basically switched positions: the public share declined from 70% to 30% in China between 1978 and 2015, while it rose from 30% to 60% in Norway.
A key difference between public wealth in Norway and China is that most of Norway’s public wealth is invested abroad. Norway’s large positive net public wealth generates capital income that is mostly used to finance further foreign capital accumulation, which in the long-run can be used to reduce the tax burden and to finance more public spending. In that sense, it is a very different form of public property than in China: in Norway public property has mostly a fiscal and financial dimension, not so much an industrial or control dimension (although Norway’s sovereign fund is sometime also used to promote certain policies, e.g., social or environmental objectives).
It is worth noting that China’s net foreign asset position, although it has increased substantially in the past 15 years (about 25% of national income, vs. less than 2% of national income in 2000) remains relatively modest, not only as compared to oil countries like Norway (over 250% of national income in 2015), but most importantly as compared to Japan (78% in 2015) and Germany (35%). In contrast the national wealth-national income ratio is now higher in China than in Japan and other developed countries.
In other words, as compared to the other two major countries with positive net foreign wealth (Japan and Germany), China’s wealth accumulation is primarily driven by domestic capital accumulation.
Decomposing wealth accumulation
How can we explain the sharp increase in China’s national wealth-national income ratio over the last decades? The high Chinese saving rates are obviously an important contributor, but they are not sufficient to account for the full increase. The other part of the explanation is the rise of equity and housing prices, above and beyond the rise in consumer prices. By our estimates, saving explains 50% to 60% of the rise in the wealth-income ratio since 1978, while the increase in relative asset prices accounts for the remaining 40% to 50%. (See Appendix Tables A.40 to A.49, where we present detailed decompositions of wealth accumulation into volume and price effects for the 1978-2015 period).
Just like in rich countries, the rise in relative asset prices can itself be accounted for by a series of factors. First is the high demand for housing assets by Chinese households, itself maybe partly due to limited access to alternative saving and investment vehicles and to insufficient visibility on the expansion of the public pension system. Another important explanation involves changes in the legal system that reinforced private property rights: lifting of rent control, changes in the relative power of landlords and tenants, changes in the relative power of shareholder and workers. It is striking that Tobin’s Q-the ratio between the market and the book value of corporations-appears to be high in China (close to 100%, like in the United States and in the United Kingdom, as opposed to 40%-60% in Germany or Japan). Whether this reflects strong shareholders’ rights is, however, unclear at this stage: the series at our disposal are imperfect, and some of the cross-country differences in Tobin’s Q might reflect data limitations. More research is needed before we can reach firm conclusions on the quantitative importance of changes in the legal system in explaining the rise of Chinese wealth. Similarly, our series do not allow us to take a stance on the (arguably even more complicated) issue of dynamic efficiency in China.
Table 1 decomposes 1996-2015 wealth accumulation by sectors (private and public) and assets (financial and non-financial). Regarding private wealth, we find strong positive capital gains for non-financial assets-mainly housing-and no gains for financial wealth. Conversely, we find strong capital gains for public financial assets and smaller gains for public non-financial wealth. The large capital gains on public financial assets mostly come from government-owned equities, and can be linked to the reform of SOEs since 2003 and the unprecedented wave of initial public offerings of SOEs that started in 2006. China also made capital losses on its net foreign assets, in part due to the appreciation of the yuan after 2004. This explains why given despite its large current account surpluses, the net foreign asset position has increased only moderately (from -9% of national income in 2000 to 15% in 2015). If China had earned the same return on its foreign assets as on its liabilities, its net foreign asset position would reach around 35% of national income today.
Last, we present series on domestic financial intermediation. The ratio between total domestic financial liabilities (i.e., total debt and equity issued by households, the government, and the corporate sector combined) and total domestic capital has risen from 60% in 1978 to 140% in 2015. This is a substantial rise, starting from a situation of limited financial development. Despite this rise, however, the level of financial intermediation remains much lower in China than in Western countries, where the financial intermediation ratio rose from 100-140% in 1978 to 200-300% in 2015.
The fraction of domestic financial liabilities owned by the rest of the world reaches about 5% in China in 2015, as compared to almost 10% in Japan, 15% in the United States and 25-30% in Germany and France.
These differences partly reflect size effects: European countries are smaller, and if we were to consolidate ownership at the European level, the rest of the world would own only about 15% of European wealth (like in the United States). But there seems to be more than this: Asian countries-Japan and even more so China-seem to be less open to foreign ownership than Europe and North America.
