Are China’s regional agricultural productivities converging: How and why?

This article tests the hypotheses of convergence to a single level of total factor productivity (TFP), and a steady state of TFP growth rate in China’s agricultural sector. Based on multilateral TFP estimates we found that China’s agricultural sector has rebounded in recent years from a slower TFP growth in the 2005–2007 period. While convergence test results confirm a “catch-up” effect that provinces with lower TFP levels tend to grow faster than others, estimated rates of β convergence are conditional on how we capture the heterogeneity effect across regions. The rates of β convergence range from 0.016 to 0.039 under different model specifications. Estimates show that higher growth rates of educational attainment, R&D, and intermediate goods density (per unit of labor) can enhance TFP growth. Unfortunately, there is no evidence of an overall σ convergence, indicating that TFP levels are not converging except in the South region. It implies that to catch up with leading provinces, it would require extra efforts for those lagging behind by increasing their region-specific research investment, promoting rural educational attainment, and enhancing embodied technical change.     

Overcoming the “Solow paradox”: Tariff reduction and productivity growth of Chinese ICT firms

This paper examines the phenomenon of the “Solow paradox” in China using the Annual Survey of Industrial Production database and the China Customs Records dataset from 1998 to 2007. We find that China likely fell into the Solow paradox in the period 1998–2002, but the total factor productivity of information and communication technology (ICT) enterprises has achieved rapid growth since 2003. Accession to the World Trade Organization is the key reason for China to overcome the Solow paradox, that is, input tariff reduction significantly promoted the productivity of ICT firms. A series of validity and robustness checks confirmed the results. Mechanism analysis shows that input liberalization promotes the productivity of ICT firms through optimizing factor structure, importing more and high-quality inputs, and increasing research and development investment. The conclusions provide strong empirical evidence for developing countries to overcome the Solow paradox through trade liberalization.     

Productivity Growth in the Chinese Economy by Industry and the Role of Foreign Capital

I. IntroductionIt is well known that China’s reform and open-up policy initiated in 1978 had an extremelylarge impact on the Chinese economy. This policy represented an about-face against thetraditional self-reconstruction strategy that China had maintained since the founding ofthe people’s Republic in 1949. Although China’s economy temporarily fell into confusionfor a few years after the Tian-an-men incident in 1989, China continued to record high GDPgrowth. Moreover, after Deng Xiao…

Sequential Malmquist Indices of Productivity Growth: An Application to OECD Industrial Activities

The paper applies both the standard DEA methodology with contemporaneous frontiers and DEA with sequential frontiers to study changes in productivity and efficiency in manufacturing for a sample of eleven OECD countries over a twenty-year period. It uses a decomposition of the industrial Malmquist productivity indices to locate the sources of productivity growth: 'technical progress' and 'catching up.' The alternative indices are interrelated in a unifying framework that provides an interpretation to their difference. We argue that for manufacturing industries, in which technological regress is unlikely to occur, DEA with sequential frontiers provides a more adequate measure for the contribution of technical changes than standard DEA.     

进口贸易与经济增长的研究综述

Rich Nations, Poor Nations: How Much Can Multiple Equilibria Explain?

This paper asks whether the income gap between rich and poor nations can be explained by multiple equilibria. We explore the quantitative implications of a simple two-sector general equilibrium model that gives rise to multiplicity, and calibrate the model for 127 countries. Under the assumptions of the model, around a quarter of the world’s economies are found to be in a low output equilibrium. We also find that, since the output gains associated with an equilibrium switch are sizeable, the model can explain between 15 and 25% of the variation in the logarithm of GDP per worker across countries.     

CEO的金融背景会提高企业全要素生产率吗?

作为最重要的人力资源之一，CEO的个人特点对企业全要素生产率具有重要影响。我们采用2008-2017年间全部A股上市公司作研究样本，结果发现：金融背景的CEO具有更冒险的行事风格，更熟悉金融领域操作规范，能够帮助企业提高创新水平和投资效率，从而提高企业全要素生产率，并且在采用DID控制内生性后依然显著。进一步地，CEO的这种影响在更能够发挥CEO个人影响力的低盈利企业和非“北上广深”地区企业更显著。本文的结论佐证了“高层梯队理论”和“烙印理论”中CEO个人特点能够对企业生产经营产生影响的结论，同时，为今后企业是否聘任金融背景的CEO提供新的思考，金融背景的CEO虽然具有更冒险的行事风格，为企业带了一定风险，但也能够在提高企业生产率水平中发挥一定作用。     

中国船舶工业绿色全要素生产率及影响因素分析——基于ML生产率视角对“波特假说”的再检验

选用船舶工业宏观数据和资源环境约束等作为基础数据,运用方向性距离函数和ML指数测算了中国船舶工业绿色全要素生产率(Total Factor Productivity),通过面板模型系统考察了环境规制、技术进步对中国船舶工业绿色全要素生产率的作用。发现从长远来看,绿色全要素生产率呈增长趋势且具有明显的收敛特征,技术进步和技术效率共同推动船舶工业绿色全要素生产率的增长,但整体上绿色全要素生产率低于传统全要素生产率。运用动态面板模型分析中国船舶工业绿色全要素生产率的影响因素,结论表明:较高的技术水平能显著提高绿色全要素生产率,而对国际市场的过度依赖阻碍了船舶工业绿色全要素生产率的增长。环境规制对船舶工业绿色全要素的增长已经带来"补偿效应"从而提高了中国船舶工业的国际竞争力,为考察船舶工业绿色竞争力提供了新的视角。     

公共支出对我国技术效率的影响分析

文章首先应用随机前沿方法,估计了我国31省市的时变随机前沿生产函数模型,结果表明提高公共支出占GDP的比例能显著地降低技术效率,而提高公共支出的组成部分占GDP的比例对技术效率有显著的促进作用,其现实意义就是优化公共支出结构对我国的技术效率有促进作用.其次,计算了我国31省市的技术效率,结果发现东部与西部之间的技术效率差距较大,而且在进一步扩大之中.再次,对TFP变化率进行了分解,分析表明:不论是从全国还是从东中西部三地区看,对技术效率影响最大的因素都是规模经济性,而技术进步和资源配置效率影响较小.最后,根据我国目前以规模经济性对TFP变化率为主要影响因素的实际情况,指出从公共收支视角来提高技术进步和资源配置效率对TFP变化率的影响,缩短东西部技术效率的差距,是一条高效率的公共支出发展之路.
