The direct impact of the relocation of farm labour on Chinese grain production

The shift from collective to household-based farming and the move towards a market economy have increased the opportunity cost of grain production and caused a withdrawal of labour from grain farming in China. Since Chinese grain production is important to both China and the world, there are concerns about whether such a farm labour relocation will have a destructive impact on China's grain production. The previous production function studies ignored the effects of changes in labour quantity and quality on grain production. Using recently available sample survey data on Chinese farm households, this paper incorporates production function analysis with human capital analysis to examine the direct impact of the relocation of farm labour on China's grain production. It has found that the relocation of farm labour has not harmed the Chinese grain production in general, but its impact varies across regions with different factor endowments that affect the choice of farming technology.     

Does China Transfer Productivity Enhancing Technology to Sub‐Saharan Africa? Evidence from Manufacturing Firms*

Abstract: This paper considers whether trade between China and sub‐Saharan Africa results in productivity‐enhancing technology transfers to sub‐Saharan African manufacturing firms. As trade flows between countries potentially results in interactions that lead to technological improvements in the production of goods and services, we parameterize the level of total factor productivity for African manufacturing firms as a function of foreign direct investment flow, and for the country in which it operates, trade openness with China, and its interaction with foreign direct investment. With micro‐level data on manufacturing firms in five sub‐Saharan African countries, we estimate the parameters of firm‐level production functions between 1992 and 2004. Our parameter estimates reveal that across the firms and countries in our sample, there is no relationship between productivity‐enhancing foreign direct investment and trade with China. In addition, increasing trade openness with China has no effect on the growth rate of total factor productivity. To the extent that total factor productivity and its growth is a crucial determinant of economic growth and living standards in the long run, our results suggest that increasing trade openness with China is not a long‐run source of higher living standards for sub‐Saharan Africa.     

The human cost of China's industrial growth

This paper examines whether industrial growth during economic development is associated with a high workplace fatality rate by using panel data from China. Controlling for provincial and year fixed effects, our estimations show that provincial industrial growth has a positive impact on the workplace fatality rate. We also find that both the growth of industrial labor productivity and the growth of industrial employment have an impact on workplace fatalities. Our instrumental variable fixed effects estimations, which control for simultaneity, show an even greater effect of industrial growth on the fatality rate. Our empirical findings suggest that the Chinese government ought to reconsider its growth-centered policies to save lives.     

Opening up,Market Reform,and Convergence Clubs in China*

This paper evaluates the relationship between initial government policies and the emergence of convergence clubs in post‐reform China. We test the structural stability of a global convergence equation using China's provincial data over the period 1985–2000. We find that the provinces cluster around two basins of attraction defined by initial opening‐up. Domestic market reform exerts a positive and significant influence on provincial economic growth but has no threshold effect. The two convergence clubs exhibit strikingly different growth behaviors, suggesting that the roles of some growth‐promoting factors, such as human capital and infrastructure, depend on whether an openness threshold is passed.     

Total Factor Productivity Convergence in Developing Countries: Role of Technology Diffusion

In recent years, though total factor productivity (TFP) convergence phenomenon has gained tremendous importance yet further deliberations for identification of catalytic factors that can help developing countries to achieve their steady developmental paths, are under way. Against this backdrop, present study investigates the principal determinants of TFP convergence by employing data of 91 developing countries over the period 1960–2015 and with USA being the frontier country. In concordance with the existing literature, main focus remains on technology diffusion for the catch‐up process and is measured by means of trade openness (TO) and foreign direct investment (FDI) with introduction of their interaction terms. However, TFP is computed by incorporating the Growth Accounting Model while empirical results are drawn from the 2‐step GMM estimation technique. It is surfaced that though high degree of openness benefits TFP growth and convergence but FDI has a dominating role. Therefore, governments can play a competent role via unflagging efforts in ensuring that the right kind of policies are enacted, promoting trading activities and FDI flows.     

经济开放度的再测算与中国经济增长

文章基于中国1985-2013年的货物贸易、服务贸易、直接投资和间接投资数据,结合AHP层次分析法和熵权法重新测算了中国整体经济开放度,在此基础上构建计量模型。研究发现经济开放对中国经济增长具有非线性的促进机制:经济开放度的提升既通过吸引FDI增加了可直接利用的资本要素,又通过FDI技术溢出和开放度程度的增加提高了全要素生产率。但加入WTO之后,经济开放度的提升对经济增长的促进作用开始下降。经济发展驱动力开始由对外开放向对内深化改革和结构转型转变。     

Openness and total factor productivity in Swedish manufacturing, 1980–1995

Openness and Total Factor Productivity in Swedish Manufacturing, 1980–1995. — This paper studies the effect of openness on total factor productivity (TFP) growth. Using industry-level data for Swedish manufacturing from 1980 to 1995, the paper shows that integrated industries tend to be more engaged in R&D and have more entry and exit activity than other industries. The results show that domestic R&D intensity does not contribute to the TFP growth rate. Instead, openness to international markets, which helps facilitate technology spillovers, is an important factor. There is also some evidence that producers exiting the market are less productive, implying that such exits will increase the average productivity of the industry.     

An analysis on technical efficiency in post-reform China

This paper employs a fully nonparametric stochastic frontier model with time and individual effects to study technical efficiency in China's post-reform economy. The panel data cover China's thirty provinces for the period of 1985–2008. The empirical results show that the average output elasticity of labor is larger than the other two inputs of capital and human capital. Based on the specified inefficiency Tobit model, the factor analysis on technical efficiency shows that the time effects of technical efficiency in China's post-reform economy are significantly contingent on the factors. There exists significant regional differences in technical efficiency in China's economic development, and a number of policy implications can be drawn.     

Inter-industry Technology Spillover Effects in China： Evidence from 35 Industrial Sectors

The present paper calculates 35 industrial sectors’ similarity matrices for the period of 1997-2008 using China’s input-output tables for 1997,2002 and 2007,and uses these to measure inter-industry technology spillover to analyze the spillover effects on industrial sectors’ labor productivity.The empirical analysis shows that inter-industry technology spillover has a significant positive effect on the labor productivity of each industry.The elasticity of productivity effects of inter-industry technology spillover is not only larger than that of direct R&D input,but also increases over time.We group the industries into four major categories and find that the inter-industry technology spillover effect within the categories is,on average,greater than that between the four categories,indicating that technology spillover occurs more easily between similar industries.This research shows that the interindustry technology spillover effect in China has begun to increase,and the government should take advantage of this effect.     

Agglomeration and productivity: Firm-level evidence from China's textile industry

Is the spatial concentration of manufacturing activity able to enhance firm-level productivity? This question is particularly relevant to production in China, which has a huge territory and population, but a skewed distribution in terms of urban–rural development. This paper aims to examine the dynamics of industrial agglomeration and the impact of agglomeration on firm-level productivity in China's textile industry by using a firm-level panel dataset from 2000 to 2005. First, the average value of the Ellison–Glaeser (EG) index (city level) is found to be approximately 0.00019. Moreover, the calculated city EG index of spatial concentration for each year exhibits a decreasing trend of spatial agglomeration for garments and other fiber products, but an increasing trend for the textile industries' agglomeration in China. The above findings are similar to the findings of Lu and Tao (2009). Secondly and importantly, this study finds an inverted U-shape relationship between agglomeration and productivity. It suggests that while industrial agglomeration enhances firms' productivity, agglomeration diseconomies may appear if the degree of agglomeration is too high.     

南北经济收敛性与共同富裕

区域经济收敛有利于协调区域发展,从而有助于实现我国共同富裕的奋斗目标。然而我国幅员辽阔,区域经济差距由来已久。当下,从GDP总量的角度来看,我国区域经济格局呈南北经济差距扩大的态势。文章利用我国284个地级市文章中的284个地级市还包括4个直辖市。2000—2019年面板数据,探析了南北经济差距演变情况。首先,基于σ收敛和dagum基尼系数分析了人均实际GDP演变特征;其次,构建β收敛模型分析了南北经济收敛性,并考察了人力资本、物质资本、技术水平、对外开放和财政支出对南北经济收敛的影响;最后,文章从共同富裕的视角,对我国西南、西北和东北地区与其他地区的经济收敛性进行探讨。研究发现:(1)南北区域经济存在显著的俱乐部效应,南方内部经济由收敛演变为不具有显著收敛特征,而北方内部经济差距均呈收敛趋势;(2)适度的人力资本的流动不会导致经济发散,物质资本总体上延缓区域经济收敛速度,财政支出对区域经济收敛的作用有限,而技术水平和对外开放对经济收敛速度的影响不稳定;(3)从实现共同富裕的总体目标来看,西北地区的经济表现与其他地区存在显著差异,东北和西南的小部分区域也需要引起一定的重视。对此文章提出合理化建议,以期更好实现共同富裕目标。     

Has China run out of surplus labour?

Many recent studies claim that China has reached a Lewisian ‘turning point’ in economic development, signalled by rising wages in urban areas and the exhaustion of rural surplus labour. In this paper we show that despite some evidence of rising nominal urban unskilled wages between 2000 and 2009, there is little in the data to suggest that this wage increase has been caused by unskilled labour shortages. China still has abundant under-employed workers with very low income in the rural sector. We argue that China's unique institutional and policy-induced barriers to migration have both prevented many rural workers from migrating to cities and also reduced the migrants' length of stay. We project that under alternative institutional settings, the migrant stock could easily be doubled from the current 150 million to 300 million by increasing either the average length of migrant stay, or the migrant inflow, or both.     

Classification of Growth Clubs and Convergence： Evidence from Panel Data in China, 1981-2004

This paper uses provincial panel data to examine club convergence in China during 1981–2004. We estimate the province‐specific initial technology level, A(0), and classify the Chinese economy into “developed club” and “underdeveloped club” based on the economic characteristics of A(0), instead of on geographical location. We find significant evidence of conditional convergence across provinces, and that the convergence speed in the developed club is faster than that in the underdeveloped club. We also find that: (i) human capital accumulation contributes more than physical capital does to club convergence; (ii) there is a positive correlation between infrastructure and growth convergence at the national level and within the developed club, while the spillover effect of infrastructure has not been developed in the developing club; and (iii) the effect of economic openness on convergence is tiny, and insignificant across and within clubs.     

Dynamic estimation of the relationship between trade openness and output growth in Asia

This paper studies the relationship between trade openness and output growth for a sample of twenty-three Asian countries using both a static OLS and a dynamic ECM estimation models. At the country specific level, the findings of this study provide robust empirical evidence indicating that higher revealed trade openness is not the main engine explaining the Asian economic-growth miracle. In particular, the authors find that physical capital accumulation is at the core of the observed long-run output per worker growth. At the regional level, the authors observe a marked difference between the pre and post 1997–1998 financial crisis, whereas, in the post period, trade openness has a positive and significant effect on output growth. In general, the results from the dynamic estimations prove that the conventional OLS static estimates underestimate the effect of investment on output growth. In addition, the dynamic model allows for a separation of gains from trade between short term and long term. The paper results also provide evidence in support of the idea that, countries with a growing degree of trade openness may experience faster per-capita output growth through gains in productivity associated to capital accumulation, rather than the assumed technological spillover effects from the trading sector. Again, at the regional level in the post financial crisis period both short term and long term gains from trade are relevant to growth. Why more trade does not necessarily imply faster growth at all levels of revealed trade openness growth, remains a conundrum.     

Environmental growth convergence among Chinese regions

Since the end of the 20th century, numerous studies have analyzed Chinese economic development to gauge whether China's rapid growth is sustainable. Most of these studies focused on assessing total factor productivity (TFP) in Chinese mainland provinces but suffered from methodological weaknesses by assuming constant returns to scale (CRS) for the production frontier and/or incorrectly modeling variables returns to scale (VRS) technology taking into account bad output such as carbon dioxide emissions. Our paper offers a right non-parametric programming framework based on weak disposability and VRS assumptions to estimate environmental growth convergence among Chinese regions characterized by size heterogeneity. We explicitly separate regional efficiency gaps into two components: The first studies the technical catching-up process on each one (technical effect), and the second reveals convergence or divergence in the combinations of input and output among regions (structural effect). Moreover, carbon shadow price levels for provinces can be derived through the dual version of our activity analysis framework. Our empirical work focuses on 30 Chinese regions from 1997 to 2010. The results emphasize that environmental growth convergence among regions has mainly relied on the structural effect. We find that the structural effect largely depends on the pollution cost convergence and not on the evolution of the relative prices of capital or labor. The carbon shadow price is increasing at an annual rate of 2.5% and was evaluated around 864 yuan per ton in 2010 in China while regional estimates show significant disparities at the beginning of the period.     

Transactional activities and total factor productivity growth in Taiwan

Total factor productivity (TFP) growth shows how rapidly an economy is enhancing technology and the efficiency with which it allocates resources. It has been argued that “miraculous” growth in East Asian economies may not be sustainable, due to relatively low rates of TFP growth. Among these economies, it appears that Taiwan has indeed exhibited substantial technological progress. Failure to control for transactional activities, however, can distort the impression of TFP growth. This study recalculates Taiwan's TFP growth for the 1957–1993 sample period, adjusting for transaction costs in the government and private sectors. For the early years of the sample, 1957–1973, the economy's technological progress is better than GDP-based calculations suggest. In recent years, 1983–1993, productivity improvement has been overstated, but the economy has still exhibited relatively fast TFP growth.     

China has reached the Lewis turning point

In the past several years, labor shortage in China has become an emerging issue. However, there is heated debate on whether China has passed the Lewis turning point and entered a new era of labor shortage from a period of unlimited labor supply. Most empirical studies on this topic focus on the estimation of total labor supply and demand. Yet the poor quality of labor statistics leaves the debate open. In this paper, China's position along the Lewis continuum is examined though primary surveys of wage rates, a more reliable statistic than employment data. Our results show a clear rising trend of real wages rate since 2003. The acceleration of real wages even in slack seasons indicates that the era of surplus labor is over. This finding has important policy implications for China's future development model.

A GROWTH MODEL FOR SOUTH AFRICA

We examine the South African growth experience during 1960‐2005 using an intertemporal growth model. The model combines old growth theory investment dynamics and new growth theory endogenous productivity growth. The consumption and investment decisions are intertemporal and assume open capital markets. Structural change is captured by separating the traded and nontraded sectors, and sectoral productivity growth is determined in a barriers‐to‐growth framework. Calibration of the model shows how the growth experience combines neoclassical convergence, technology spillovers with barriers and productivity‐investment interaction. Counterfactual analysis shows the growth costs of sanctions and protectionism. The suggested model is an alternative to existing growth modelling in South Africa, in which investments are short‐sighted and productivity growth is imposed exogenously.
