IS CORPORATE R&D INVESTMENT IN HIGH‐TECH SECTORS MORE EFFECTIVE?

This paper discusses the link between R&D and productivity across the European industrial and service sectors. The empirical analysis is based on both the European sectoral OECD data and on a unique micro‐longitudinal database consisting of 532 top European R&D investors. The main conclusions are as follows. First, the R&D stock has a significant positive impact on labor productivity; this general result is largely consistent with previous literature in terms of the sign, the significance, and the magnitude of the estimated coefficients. More interestingly, both at sectoral and firm levels the R&D coefficient increases monotonically (both in significance and magnitude) when we move from the low‐tech to the medium‐ and high‐tech sectors. This outcome means that corporate R&D investment is more effective in the high‐tech sectors and this may need to be taken into account when designing policy instruments (subsidies, fiscal incentives, etc.) in support of private R&D. However, R&D investment is not the sole source of productivity gains; technological change embodied in gross investment is of comparable importance on aggregate and is the main determinant of productivity increase in the low‐tech sectors. Hence, an economic policy aiming to increase productivity in the low‐tech sectors should support overall capital formation.     

Comparisons of real output and productivity of Chinese and Indian manufacturing, 1980–2002

The principal objective of this paper is to compare the real output and labour productivity of Chinese and Indian manufacturing from 1980 to 2002. Using an industry-of-origin approach, purchasing power parities (PPPs) for the benchmark year 1985 are derived from the Chinese and Indian industrial censuses. In turn, the PPPs are used to convert Indian manufacturing GDP into Chinese yuan for direct comparisons. Secondary objectives are twofold: first, to set this direct comparison within the general context of the economic policy reform process followed in each country, and second, to compare and contrast the organisation and structure of both countries' manufacturing sectors. The analysis shows that since 1980, real value added and labour productivity growth for Chinese manufacturing has been well above Indian levels.     

How migration restrictions limit agglomeration and productivity in China

China strongly restricts rural–urban migration, resulting in a well acknowledged surplus of labor in agriculture. But migration is also restricted within sectors. This paper argues that these intra-sector restrictions lead to insufficient agglomeration of economic activity in both the rural industrial and urban sectors, with resulting first order losses in GDP. For urban areas the paper estimates a city productivity relationship, based on city GDP numbers. The effects of access, educational attainment, FDI, and public infrastructure on productivity are estimated. Given these, worker productivity is shown to be an inverted U-shape function of city employment, with the peak point shifting out as industrial composition moves from manufacturing to services, as predicted by urban theory. As far as we know this is the first paper to actually estimate the relationship between output per worker and city scale for any country. The majority of Chinese cities are shown to be potentially undersized—below the lower bound on the 95% confidence interval about the size where their output per worker peaks. The paper calculates the large gains from increased agglomeration in both the rural industrial and urban sectors.     

Role of International Trade in Chinese Economic Development

This study examines the interdependency between Chinese agricultural and industrial sectors. A dual economic model was developed to investigate the relationship between the two sectors and factors affecting Chinese economic development. The study reveals that inputs, such as labor, are important to Chinese economic development. Capital investment contributed to the growth of the Chinese industrial sector. The results also suggest that foreign trade has made a significant contribution to economic development. Growth of the Chinese agricultural sector seems to depend on industrial growth, but growth of the industrial sector does not rely on agricultural growth.

Structural Change and Economic Growth in China

This study develops a new analytical framework to account for sources of rapid economic growth in China. The traditional Solow approach is expanded to include another source of economic growth—structural change. The empirical results show that structural change has contributed to growth significantly by reallocating resources from low‐productivity sectors to high‐productivity sectors. It is found that the returns to capital investment in both agricultural production and rural enterprises are much higher than those in urban sectors, indicating underinvestment in rural areas. On the other hand, labor productivity in the agricultural sector remains low, a result of the still large surpluses of labor in the sector. Therefore, further development of rural enterprises and an increase in labor flow among sectors and across regions are key to improvements in overall economic efficiency.     

STRUCTURAL CHANGE AND THE GROWTH OF INDUSTRIAL SECTORS: EMPIRICAL TEST OF A GPT MODEL

This paper investigates the empirical relevance of a model of structural change and the growth of industrial sectors. The model analyzes the process of diffusion of general‐purpose technologies (GPTs) and how this affects the dynamic performance of manufacturing and service industries. The empirical analysis studies the dynamics and the determinants of labor productivity growth for a large number of sectors in 18 OECD countries over the period 1970–2005. The results of dynamic panel data and cross‐sectional analysis provide support for the empirical validity of the model. Industries that are close to the core of ICT‐related GPTs are characterized by greater innovative capabilities and have recently experienced a more dynamic performance. Relatedly, countries that have been able to shift their industrial structure toward these high‐opportunity manufacturing and service industries have grown more rapidly.     

Valuing water for Chinese industries: a marginal productivity analysis

A marginal productivity approach is developed for valuing industrial use of water and applied using data from Chinese industrial firms, where water, as well as capital, labour and raw materials, are treated as inputs to a production function. Models on price elasticity of water demand associated with the marginal productivity approach are also developed and estimated for different Chinese industrial sectors.     

The economic and environmental performances of rural districts in Italy: Are competitiveness and sustainability compatible targets?

This paper analyses the economic performances of the rural system and the level of land sensitivity to degradation in Italy. Three indicators (district value added, share of agriculture on total product, and a composite index of land sensitivity) were used to classify 784 Italian local districts into eight performance classes. Four classes share a combination of high environmental quality (in terms of land degradation), high (or low) economic performances, and high (or low) productivity of the primary sector. The remaining four are characterised by a combination of low (and declining) environmental quality, high (or low) economic performances, and high (or low) productivity of the primary sector. The eight classes were grouped into four ‘environmental quality’ types and four ‘target performance’ categories to discriminate among high- and low-performance districts by considering twelve additional variables within a Discriminant Function Analysis (DFA). 148 high environmental performance districts (18% of total) were identified mainly across the Alps and Apennine while 314 districts (41%) were classified in the lowest performance class and concentrated in flat areas of southern Italy. The districts with high environmental performances were characterised, on average, by medium to low district value added, moderately low economic weight of the primary sector, and tourism specialisation. Districts with high economic performances and low environmental performances were characterised by high sensitivity to LD, low district value added, high share of agriculture in total product, and the lowest productivity of labour in all economic sectors. In these districts the risk of entering a downward spiral of rural poverty and environmental degradation is potentially high.     

The Effects of Public Capital on the Growth in Spanish Productivity

The aim of the article is to provide new evidence concerning the effect of public capital on productivity growth in Spain. To this end, the article follows the growth accounting approach, which, in addition to measuring both the direct and indirect effects of public capital on the total factor productivity, allows for assessing whether there is a distinctive impact of public capital across economic sectors. The results lead to three main conclusions: (1) Public capital has a strong influence on growth when we use data from the whole economy; (2) this influence varies across sectors, being more relevant in the exposed sectors (industry) than in sheltered sectors (agriculture, construction, and services); and (3) irrespective of the definition used for public capital, these basic results remain unchanged.

DOES MARKET‐ORIENTED ECONOMIC TRANSITION ENHANCE ENTERPRISE PRODUCTIVITY? EVIDENCE FROM CHINA'S ENTERPRISES

Using a panel of China's enterprises from 1999 to 2007, this paper examined how market‐oriented economic transition affects the productivity of China's enterprises given the various stages of enterprises in the commercialization process and given the market segmentation among Chinese different regions. The main findings are that: (i) enterprises with higher degrees of commercialization have relatively higher productivity, whereas enterprises with higher degrees of market segmentation have relatively lower productivity; (ii) the commercialization process and market segmentation act indirectly affect productivity through enterprises' capacity to export, innovate and obtain business loans; and (iii) the indirect effects are found to be significantly different between the commercialization process and market segmentation, highlighting the effects of the market‐oriented economic transition on enterprises' productivity. This paper provides reliable enterprise‐level evidence regarding the sources and evolution of enterprise productivity during different stages of market‐oriented economic transition in China.     

Environmental spillover effects on firm productivity and efficiency: An analysis of agri-food business in Southeast Spain

Spillover effects are treated as the influence of knowledge and innovation diffusion on an economic activity, but their analysis related to environmental practices within firms is still quite scarce. This study investigates the effect of environmental practices and related spillovers on productivity and efficiency in agri-food firms located in Southeast Spain. The low investment in research and development actions in comparison with the industrial sector, together with the relatively recent application of environmental requirements and the heterogeneity of environmental controls within firms have led to important changes in the organisation and management of their productive activity. These features are especially related to the implications that location and clustering factors have on environmental knowledge and innovation diffusion. Taking environmental management practices as knowledge of capital, we propose a specific analysis that evaluates the impacts of both environmental investment and spillover on the production function. The results indicate the relationship between productivity improvement and environmental practices, also showing the presence of positive spillovers. In a second-stage analysis, the incidence of environmental variables on the individual technical efficiency of firms is also determined. On the whole, the empirical analysis provides evidence of the links between environmental practices spillovers and economic performance.     

Growth,economic structure,and residential distribution of a small city

This article presents a growth model of a small open city with economic structure and geography. The city which is located along a line segment has three, industrial, services and housing, sectors. The spatial growth model of a small city synthesizes the main ideas in some important models in the neoclassical growth theory, urban economics, and the literature of economic growth of small open economies. We show that the dynamic system has a unique equilibrium. We also simulate the motion of the urban economy over time and space. The unique feature of our approach is to treat production activities, economic structure, residential distribution, capital accumulation, and consumption on the basis of microeconomic mechanism as an integrated whole. Our simulation provides some important insights into the processes of the urban economic growth. For instance, under certain conditions, when the industrial sector’s productivity is increased, the wage rate, price of services, capital intensities of the services and industrial sectors, and per-worker output levels of the two sectors are increased. The total labor supply, the capital stocks employed by the three sectors and the labor forces by the service and industrial sectors are all increased. The shares of the three sectors are not affected by the technological change in the long term, even though the shares are initially affected. The per capita consumption level of the industrial goods rises and the consumption level of services falls. The land and housing rents are increased and the consumption of housing per household falls. Moreover, the current account balance tends to be more in surplus and the growth rate is increased.     

Home-country environment and firms’ outward foreign direct investment decision: Evidence from Chinese firms

This paper takes a holistic view and examines the environmental effect of the home country on firms’ outward foreign direct investment (OFDI) decisions. We construct an economic growth index to assess the overall economic environment of Chinese regions and find that the home country’s business environment is negatively associated with firms’ decisions to invest abroad, and that such a negative relationship can be intensified for firms with state ownership or without an export network. Moreover, unlike previous literature, we look at both the environmental effect on OFDI decisions and the consequential impact of OFDI on firm performance. We employ propensity score matching and difference-in-differences methods, as well as the Heckman two-step model, for our estimations. Our results show that OFDI does indeed improve Chinese firms’ productivity and sales. This paper, therefore, contributes to the literature by identifying a range of home country business environmental factors that have a combined effect on firms’ OFDI decisions, adding to a more comprehensive understanding of OFDI originating from emerging economies.     

Structure and performance of the service sector in transition economies1

This paper examines the performance of the service sector in the Eastern European transition economies during the 1997–2004 period. The performance of the service sector as a whole and of its sub‐sectors is very heterogeneous within the region. Service sub‐sectors that are information and communications technology producers or users and those using skilled labour more intensively exhibit the highest labour productivity growth. Our estimates show a positive and significant effect of liberalization on service labour productivity growth that is stronger for sub‐sectors that are more distant from the technological frontier. Service liberalization is also shown to have a positive effect on labour productivity levels and growth of downstream manufacturing industries.     

Ownership, Productivity Change, and Financial Performance in Chinese Industry

This paper investigates Chinese industrial productivity from 1980 to 1996. Results include series for foreign-linked, shareholding, and private enterprises. We find long-term productivity increase, with growth rates declining during the 1990's. Productivity outcomes outside the state and collective sectors are modest, with shareholding enterprises suffering productivity declines. The paper examines differences in marginal factor productivity across ownership types, considers the impact of business cycles on the interpretation of productivity trends, and documents a statistical relationship among the profitability of state enterprises, the relative productivity performance of state firms, and the entry of new firms outside the state sector.J.

Productivity and convergence across U.S. States and industries

We examine the sources of aggregate labor productivity movements and convergence in the U.S. states from 1963 to 1989. Productivity levels vary widely across sectors and across states, as do sectoral output and employment shares. The main finding is the diverse performance of sectors regarding convergence. Using both cross-section and time series methods, we find convergence in labor productivity for both manufacturing and mining. However, we find that convergence does not hold for all sectors over the period. Decomposing aggregate convergence into industry productivity gains and changing sectoral shares of output, we find the manufacturing sector to be responsible for the bulk of cross-state convergence.

Industrial labour productivities and tariffs in South Africa

The analysis of the effect of tariffs for labour productivity faces the challenge of tariff policy endogeneity. Tariff policy is designed to promote economic development and the industrial sector tariff structure may reflect characteristics of the industries protected. We seek to identify the effect of tariffs by taking advantage of multilateral tariff liberalization using reductions in industrial sector tariffs in other world regions as instruments for sectoral tariff reductions in South Africa. The data cover 28 manufacturing sectors over the period 1988–2003. We find that tariff reductions have stimulated labour productivity when instrumented by multilateral tariffs. The ordinary least‐squares estimates show downward bias and this confirms the endogeneity of tariffs. Investigation of channels of effects shows some support for the importance of competitive pressure and technology spillover from trade liberalization.
