摘要：

This paper first documents three important facts about Chinese economy for the past decade: i) The skill premium in wage has been rising till 2008 but falls sharply afterwards; ii) non-residential structure investment contributes the most to the surge of the aggregate investment rate since 2008; iii) on the firm level, after 2008 the return to capital is lower for firms with lower employee education level. We then use a two-sector model to show quantitatively that these features in the data are caused by distortionary government investment policy in 2008, which subsidized infrastructure sectors implicitly so that they can absorb capital at a lower than market rate. We demonstrate that such a biased policy provides a strong incentive for infrastructure sector to invest, driving up the market interest rate and aggregate investment rate while the return to capital is declining. The resulting structural changes push up the relative demand of unskilled labor and thus leads to a rising trend in wage premium. Our model is calibrated to the Chinese data and the results are consistent with the facts listed above. Our results suggest that government has strong incentive to invest in the infrastructure sector if they are only interested in the short-run output level. Moreover, such a distortionary government policy could be welfare-improving if there are abundant unskilled labor supply in the economy.
