This leads to an important question of how the relationship between misallocation and efficiency is (see [1]). The purpose of this study is to address the empirical relationship between misallocation and efficiency in the electric and computer industry in Vietnam during the 2005-2015 periods. To do this, we built a model that allowed us to evaluate the impact of misallocation and other factors on efficiency. The slack-based measured efficiency (SBM) model (Tone [2]), and the super-efficient model (Tone [3]) are used to estimate the firms’ efficiency. The approach of Hsieh and Klenow [4] is used to measure misallocation in the study area. Estimated results of the model about the relationship between misallocation and efficiency show that the variable representing the misallocation has a negative sign and statistical significance in all models. In other words, the misallocation negatively affects efficiency. The bigger the misallocation, the lower the efficiency.展开更多

Rapid accumulation of household debts, exacerbation in income inequality, tightened real sector liquidity, escalated trade tensions with the US, and weakened external demand pose key problems in China's macroeconomic landscape. The status quo is exacerbated by soaring uncertainty and weakening confidence in the face of persistent resource misallocations and institutional distortions, which cast more shadow on the already dampened consumer sentiment, sluggish private investment growth, and fallen foreign reserves. This summary report highlights the urgency of deeper structural reforms for tackling the various internal and external problems. Based on the IAR-CMM model, with both cyclical and secular factors taken into consideration, our baseline forecast of real GDP growth rate is 6.4%(6.1% using more reliable instead of the official data) in 2019. Alternative scenario analyses and policy simulations are conducted to assess the consequences of possible downside risks and the corresponding policy options needed to ensure the assumed growth targets. These analyses lead us to conclude that comprehensively deepening reform and opening up, which should be both rule-of-law based and market-oriented, with well-designed and well-conceived strategies that properly weigh short-, medium-, and long-term benefits and costs, should continue to be set as the guidance for China's transformation into a phase with sustainable and high-quality growth.展开更多

The results show that neglecting LGD may overstate economic performance in Chinese provinces. The eastern region shows better performance in single jactor efficiency and total factor efficiency than the non-eastern regions. The western region shows the worst total factor performance. The north-eastern region is the only region that has experienced a decline in total factor performance. The state-dominated, investment- driven development model may help technological progress across Chinese regions but could lead to significant factor misallocation. We argue that biases towards more state- dominated investment and land supply in less productive western, central and north- eastern regions, at the expense of investment and land supply in more productive eastern regions, have contributed to the recent slowdown in economic growth in China. Therefore, .further market-oriented reforms in factor markets should be considered in the future.展开更多

Since 2003, government policies have aimed to distribute more resources to less developed areas. Although this process is accompanied by a narrowing interregional income gap, it does not represent real "convergence" between regions. From the perspective of spatial-political economics, the free movement of people is helpful to realize regional economic balance through agglomeration, while investment policies that deviate from the comparative advantage of less developed regions may lead to spatial misallocation of resources and unsustainable economic growth. In order to achieve further integration and development in the Chinese economy in the future, restrictions to the flow of production factors must be alleviated so that the market can truly become a decisive force for the allocation of resources.展开更多

Based on household data from the China Family Panel Studies of 2012, the present paper quantifies the potential distortions in China 's agricultural production and examines their underlying determinants across regions. The results reveal that there are different levels of distortions across regions. The Middle region is facing the greatest distortion. Increases in machinery input, the proportion of non-farm income and effective labor input will reduce distortions. Household saving, farmland rent and farmland size are significantly positively related to distortions. There is a complementary effect between labor and farmland in alleviating production inefficiency, but substitution effects exist between capital and farmland and also capital and labor. The increase in farmland size will aggravate the impact of capital on distortions. Given the constraint of super small-scale farmland, facilitating land transfer is a necessary precondition for improving, allocative efficiency.展开更多

In this article, I highlight several key internal factors that have hindered China's growth in recent years. These include worsening misallocation of resources and declining growth of total factor productivity, plus rising household income inequality and debt overhang in the face of tightened liquidity constraint. All of these show the urgency for deepening reforms in China's key macroeconomic landscapes in order to remove institutional barriers and distortions deep-rooted in the nation's economic and financial structure, and to correct fundamental imperfections of its socialeconomic system. 1 argue that such refonns are of critical importance for China's pursuit of healthy and sustainable growth and of balanced and adequate development going forward.展开更多

Using firm-level data from Chinas 2008 economic census, we find two facts that speak to a novel mechanism of misallocation within service and between manufacturing and service sectors. First, compared with the manufacturing sector, there are more stateowned enterprises and fewer entrants in the service sector. Second, markups increase with firm size, and the increase is more dramatic among service firms. We interpret these facts through the lens of a monopolistic competition model with heterogeneous firms and variable markups. A multisector model shows a new channel that translates asymmetric barriers to entry across sectors into sectoral markup differences, which in turn cause sectoral misallocation. Quantitative analysis shows that when reducing entry barriers to service firms to the extent observed for manufacturing firms, the model predicts a 12-percentage-point increase in the service employment share.展开更多
