Exports,technical progress and productivity growth in a transition economy: a non-parametric approach for China

Theories suggesting either static or dynamic productivity gains derived from exports often assume the prior existence of a competitive market. In the presence of market imperfection and distortion, however, the competition and resource reallocation effects of exports on productive efficiency may be greatly reduced; and there may actually be disincentives for innovation. This paper analyses the impact of exports on aggregate productivity growth in a transition economy using a panel of Chinese manufacturing industries over the period 1990–1997. TFP growth is estimated by employing a non-parametric approach and is decomposed into technical progress and efficiency change. No evidence has been found suggesting significant productivity gains at the industry level resulting from exports. Findings of the current study suggest that, for exports to generate significant positive effect on TFP growth, a well-developed domestic market and a neutral, outward-oriented policy are necessary.     

总需求、国际贸易与我国省际生产率变化——基于省际面板数据的研究

全要素生产率的提高是促进经济持续增长的重要原因,对生产率的研究,主要是从供给方面展开的,本文试图从需求角度研究全要素生产率变动的原因。理论上看,总需求通过影响技术创新、技术选择、规模经济效益和要素的使用效率等途径引起生产率的变化,国际贸易则通过促进分工深化、产生技术溢出等促进生产率的提高。然后,本文采用数据包络分析方法测算了中国省际全要素生产率变化,并将其分解为技术效率的变化和技术进步。结果发现中国改革开放以来全要素生产率增长主要是技术进步的结果,技术效率的作用很小。在测算和分解的基础上,利用省际面板数据,就总需求和国际贸易对生产率增长的影响作了实证分析,发现最终消费和资本形成对技术进步和全要素生产率的提高作用显著,出口对生产率增长的作用不显著,进口显著地促进了省际全要素生产率增长和技术进步。

Analysis on total factor productivity of Chinese provincial economy

This paper applies the nonparametric DEA-Malmquist index approach to estimate total factor productivity growth, efficiency change and the rate of technological progress from 1979 to 2003. This is done to conduct analysis on the total factor productivity of China’s provincial economy. Analysis on the evolution of distribution dynamics of relative labor productivity, relative total factor productivity, relative efficiency and relative technological progress is done by using kernel density estimation for the period from 1979 to 2003 in 29 provinces of China. Our analysis indicates that disparities of provincial economic growth are large and have been increasing owing to the relatively large and increasing disparities of total factor productivity growth especially the rate of technological progress. __________ Translated from The Journal of World Economy (世界经6D4E;), 2005, (5) (in Chinese)     

FDI技术溢出渠道与中国制造业生产率增长研究:基于面板数据的分析

This paper analyses total factor productivity (TFP) of China’s manufacturing sector and its decomposed indexes, i.e., technological progress and technological efficiency by employing Malmquist productivity index based on the Data Envelopment Analysis (DEA) approach. Using panel data of domestic manufacturing sector in China from 2000 to 2005, we estimate the influences of horizontal and vertical linkages on TFP and its decomposition indexes by controlling R&D and exports indexes of domestic manufacturing sector. The empirical results show that R&D and exports have a positive effect on TFP and that FDI inflows lead to positive spillovers significantly in general mainly through technological progress resulting from backward linkages; however, forward linkages have no technology spillover effect while horizontal linkages promote TFP through technological efficiency which has quite different influencing modes compared to that of backward and forward linkages. The grouping regression results also show that FDI technology spillovers have different conductive mechanisms under different technological levels, industry concentrations and export dependency indexes.

外商在华直接投资区域聚集非均衡性的实证研究

新贸易理论认为,国际贸易是技术进步的重要原因。本文采用DEA方法将中国32个工业行业的全要素生产率增长分解为技术效率和技术进步的增长,分别就出口和进口对生产率增长的影响作了实证分析。我们发现,在1998—2003年期间,工业行业的全要素生产率增长的原因主要是各行业的技术进步增长,而不是技术效率的提高;贸易开放度高的行业并不比贸易开放度低的行业具有更高的技术效率和规模效率;出口和生产率增长的关系不显著;但进口显著地促进了工业行业的全要素生产率增长和技术进步的增长。所以,调整中国的进、出口贸易模式显得很有必要。     

How R&;D investments influence TFP growth: Evidence from China’s large and medium-sized industrial enterprises

This paper investigates the potential channels through which R&D may influence TFP growth using industry-level panel data of China’s large and medium-sized industrial enterprises over the period of 2000–2007. Comparing with existing literature, we provide a closer look of the relationship between R&D and TFP growth by decomposing TFP growth into efficiency change and technical change components using Malmquist productivity index and distinguishing between upstream R&D spillovers and downstream R&D spillovers. We find TFP grow slightly during 2000–2007, and R&D investment indeed serves as an engine of productivity growth just as endogenous growth theories argued, which is largely because R&D accelerates technical progress even it also results in enlarging technical inefficiency. However, we find a robust negative effect of downstream R&D spillovers on TFP growth, the effects of upstream is positive but not statistically significant. In addition, we do not find the positive effects of human capital on TFP as endogenous growth theories indicated, but find human capital severs as “assimilation device” for R&D spillovers both in promoting TFP growth and increasing technical efficiency even the effects on technical progress is adverse.     

Dynamic productivity growth and its determinants in the Indonesian food and beverages industry

ABSTRACT

This research investigates dynamic productivity growth and its determinants in the Indonesian food and beverages industry decomposing dynamic productivity growth into the contributions of dynamic technical inefficiency change, dynamic technical change, and dynamic scale inefficiency change. The empirical application employs unbalanced panel data of 44 subsectors in the Indonesian food and beverages industry over 1990–2014. To estimate dynamic productivity growth, this research uses a Luenberger indicator accounting for the presence of adjustment costs. The results show that dynamic productivity growth exhibits a decreasing trend. Dynamic technical inefficiency change and dynamic scale inefficiency change contribute positively to dynamic productivity growth, while dynamic technical change contributes negatively. Dynamic productivity growth is affected by the change in industrial concentration, the growth rate of capital intensity, the growth rate of exports, the growth rate of foreign direct investment, and location.

Learning-by-doing in R&D, knowledge threshold, and technological divide

This paper presents a simple R&D-based growth model of the “technological divide,” in which learning-by-doing (investing) in R&D and a threshold level of technological knowledge jointly determine the pattern of economic growth. Specifically, the model generates differences in the growth pattern primarily by modifying the underlying parameters that govern the evolution of economy-wide technological competence or dynamic R&D productivity. The technological divide arises at the threshold level of technological knowledge, which is largely affected by the quality of socio-technological infrastructure. Government policies aimed at enhancing the quality of socio-technological infrastructure can help countries escape from the “technology divide” trap by lowering the knowledge threshold. While the model preserves the spirit of the R&D-based endogenous growth model in the sense of its policy effects and the endogenous evolution of technological competence, the model does not need to reach the scale effect directly, where an increase in the size of an economy generates more rapid growth.     

Understanding Japan's Capital Goods Exports

Japan is the leading supplier of sophisticated capital goods to East Asian countries. These goods embody advanced technologies and facilitate learning and productivity growth. Capital goods also represent 30–40% of Japan's exports. This paper investigates the determinants of these exports. Results from dynamic ordinary least squares estimation indicate that exports depend on exchange rates, income in the importing countries and downstream countries' exports to the rest of the world. Results from out‐of‐sample forecasts indicate that Japanese exports crashed in 2009 because of the perfect storm of a yen appreciation, a global slowdown and a collapse in Asia's exports.     

Structural change and international competitiveness in Canada: an alternative approach

The neoclassical theory of international trade says little of relevance about the dramatic shifts in world trade patterns in the postwar period. Much of the weakness of the Hecksher-Ohlin-Samuelson model has been attributed to its assumption of globally uniform technology and thus the instantaneous international diffusion of technological innovation. In this paper we relax these assumptions, focusing instead on the role of innovation in the determination of international trade flows. We develop a disaggregated, dynamic Ricardian trade model (based on Pasinetti's 1981 growth model), in which the sectoral rate of process innovation is important in relation to the average innovation rate in the economy. The level of this ratio compared to that of foreign rivals drives long-run trends in international competitiveness. This is called the Pasinetti Trade Hypothesis (PTH). Ricardian comparative cost considerations form the logical foundation for the PTH in that they establish the conditions under which dynamic considerations are relevant. The model is tested for the case of Canada, during the period 1961–72, with the USA serving as a proxy for Canada's international competition. The rate of process innovation in a sector is measured as the rate of change in the vertically integrated labour coefficient in that sector. The results support the PTH in its pure and modified form and provide much weaker support for the static Ricardian hypothesis, indicating that in a world in which more than one country exports each good, the dynamics of structural change - process innovation - may be as important as static comparative cost considerations as a determinant of a sector's international competitiveness. The focus on international differences in technology and innovation rates gives support to government policies aimed at boosting sectoral innovation in relation to foreign rivals. At the least, a laissez-faire response to such ‘industrial tinkering’ by foreign competition may be extremely costly.     

The Sun Also Rises: Productivity Convergence Between Japan and the USA

The growth process for a technological leader is different from that of a follower. While followers can grow through imitation and capital deepening, a leader must undertake original research. This suggests that as the gap between the leader and the follower narrows, the follower must undertake more genuinely innovative R&D and possibly face a slower overall growth rate. The results of a dynamic panel equilibrium-correction model of productivity growth suggest that the productivity gap with the USA had a strong effect on the growth of Japanese manufacturing, and that changes in R&D intensity also made a significant contribution. Moreover, the effect of the productivity gap was significantly higher in industries that had higher R&D intensities, higher levels of human capital, and were more open to exports. This paper is based upon Chapter 5 of my D.Phil. thesis at the University of Oxford. It was partly written while I was a Visiting Scholar at the Foundation for Advanced Information & Research, Tokyo, and was supported by a Sanwa Bank Foundation Research Fellowship and ESRC grants R000234954 and R000237500.     

Export Performance of China: A Constant Market Share Analysis

In the light of the fact that there has been substantial growth in China's exports in last three decades, particularly after China joined the WTO in 2001, this article investigates the major sources of China's export performance during 2002-2014 by using the constant market share (CMS) model. In this study, exports are further decomposed in three categories based on their technological intensity using Lail (2000) classification on 3 digit SITC Revision-3 data provided by UN Comtrade via WITS database. The categories are high technology, medium technology and low technology. It is found that growth of China's exports has, moreover, remained above world exports growth in all three categories during the period of study. The analysis reveals that export performance is mainly attributed to 让s competitive strength in the global market, though decreasing trend has been observed in the competitiveness of all three categories. Increasing cost of labor and appreciating RMB could be the causes behind decreasing competitiveness of Chinese exports. Product structure effect, on an average, has turned out to be negative in all the categories which is the most disturbing aspect of China's export performance. On the other hand, geographical structure effect has positive impact on export performance of high-technology based exports whereas it has negative impact on export performance of low-technology and medium-technology based exports. China being the world's largest exporter, decreasing competitiveness and wrong product structure effect could adversely influence its export performance in particular and its growth in general.     

International trade and technological progress in china: Evidence from time series

Using annual time series data (1983–2007), this paper examines the nexus between international trade and technological progress in China. The time series properties of the data are analyzed by bounds testing approach and vector error-correction model. The empirical results show that, it is not international trade volume and export trade volume but the import trade volume that is cointegrated with total factor productivity. The paper also finds that, in the long run, there is a reciprocal Granger causal relationship between the change of import trade volume and the change of total factor productivity, and in the short run, there is no evidence to support the Granger causality between these changes of the two variables.     

Costs,knowledge and market structure: understanding the puzzle of international competitiveness with Greek export data

This is an analysis of the sources of international competitiveness with Greek export data for the period 1987–2007. The framework used in the study incorporates factors that do not only represent cost competitiveness but also shed light on the determinants of economic complexity. Economic complexity is the amount of knowledge capabilities embodied in exports that indicates – as a source of comparative advantage – the ability for product differentiation and product variety. The empirical analysis shows that industries benefit substantially from their own R&D activity but, owing to weak economic complexity in the country, there are no cross-industry knowledge spillovers (both at national and international level) that can benefit export activity. Greek exports were found to be sensitive to relative unit labour costs (RULC) but the most important export component of this index is relative labour productivity and not labour cost. Not all institutional arrangements have the same impact on exports, for example high trade union density might harm competitiveness but this factor is uncorrelated with R&D investment. In the view of these findings, Greece’s route to international competitiveness should be primarily by improving its economic complexity, making sure that the country specialises in productive activities that enrich its knowledge capabilities as well as increase the potential of knowledge transfer.     

Exports, Returns to Scale, and Total Factor Productivity: The Case of Taiwanese Manufacturing Industries

The paper examines the relevance of international scale economies and international market efficiency of trade based on the firm-level data of Taiwanese manufacturing industries. The author first constructs a simple analytical framework to measure the extent of scale economies and total factor productivity for each firm. The measurements of scale economies and total factor productivity are then used to investigate the relationships among exports, scale economies, and productivity. Significant external scale economies associated with exports and a strong positive relationship between the individual firm's productivity and its own export intensity are observed.     

Estimating productivity and returns to scale in the US textile industry

In light of the textile industry's growing foreign competition, trade deficit and job loss, we estimate its productivity and efficiency for the period 1975–93 utilizing a variable elasticity of substitution production function. The results indicate that, despite job losses, the industry adjusted by increasing labor productivity and maintaining fairly stable profits. This performance does not warrant protectionist policies. However, with an elasticity of factor substitution less than one and decreasing, the impact of factor price increases could result in higher apparel prices and preference for cheaper imports. Furthermore, with an elasticity of capital output rapidly decreasing, significant technological improvements will be required to improve competitiveness since textile production is capital intensive. Recently revised rules on trade liberalization could increase competition in the industry. First version received: October 1999/Final version received: August 2000     

Employment Effects of Product and Process Innovation in Europe

This paper develops a model of the employment impact of innovation considering, on the one hand, the interactions with demand and labour costs and, on the other, the variety of patterns of technological change. Different technological strategies are considered. First, a search for technological competitiveness is based on product innovation and productivity rooted in quality advantages; second a strategy of active price competitiveness has productivity growth rooted in process innovation-based restructuring; third a passive price competitiveness strategy is pursued by non-innovators relying on cost-cutting. The new European innovation database drawn from the Community Innovation Survey 1994-96, merged with structural and macroeconomic data 1994-99 drawn from the OECD are analysed at a sectoral level across eight European countries: Italy, France, Germany, Denmark, Netherlands, Finland, the UK, and Sweden. The innovation survey data provide information on several quantitative and qualitative aspects of firms' innovative activities. A comparison of the results from the first (1990-92) and second (1994-96) Community innovation survey data is also carried out. The results show that, in the last decade, technological change has had a major impact on employment in manufacturing industry, associated with the dominance of an active price competitiveness strategy.     

Technological Progress versus Efficiency Gain in Manufacturing Sectors

This study decomposes the nonparametric Malmquist productivity index for 36 Korean manufacturing sectors into two components: technological change and technical efficiency change. The empirical results show that while each sector displays quite different growth patterns, productivity growth is dominated by technological change. Technological change is found to have a negative correlation with efficiency change. Secondary regression performed in this study identifies the relationship between productivity growth measures and several key policy variables, such as effective protection rate, market concentration, and so forth. The productivity estimates are compared with those of the conventional Törnqvist productivity index.
