Industry-specific determinants of vertical intra-industry trade: the case of EU new member states’ agri-food sector

The determinants of intra-industry agri-food trade are analysed to only a limited extent in the literature. This article investigates the industry-specific determinants of vertical intra-industry agri-food trade between new member states of the EU and the other EU countries for the period 1999–2010 by applying a dynamic panel data model. Results suggest that IIT is mainly low vertical in nature, suggesting regional export of low-quality products to EU markets. Results also show that vertical product differentiation and FDI are positively related to VIIT, suggesting that quality growth and investments foster vertical intra-industry trade. As to productivity and factor endowments a negative relationship with VIIT was found, implying the labour abundant and similar nature of NMS agricultural sectors.     

化石能源价格变化影响分析——基于投入产出价格模型

利用《中国2007年投入产出表》中的数据,运用投入产出价格模型测算我国两个化石能源部门(煤炭开采和洗选业以及石油和天然气开采业)的产品价格分别单独以及同时上涨10%这3种情境下其他产业部门产品价格的变化幅度,在此基础上分析了化石能源价格上涨对其他产业部门产品价格的影响。结果显示:煤炭价格依然是对我国各部门产品价格影响最广的因素;而石油和天然气价格对其他部门产品价格的影响主要集中于个别部门。最后给出相应的政策建议。

运用区位商和聚类分析方法分析了辽宁省的产业结构层次;运用偏离-份额法,从产业结构和竞争力两个方面分析辽宁省的三次产业结构、工业产业结构对其经济增长速度、经济增长效益的影响。结果显示:在全国区域分工中,辽宁省的产业结构层次较高;辽宁省第二、三产业的快速发展促进了其经济实现较快增长;辽宁省技术含量高、附加值高的工业行业的发展水平仍较低,这些行业在区际分工中不具有优势;冶金、化工、机械制造等投资大、资本有机构成高的重化工业在辽宁省经济中仍占有举足轻重的地位。     

Technological leadership and sectorial employment growth: A spatial econometric analysis for U.S. counties

This paper studies the determinants of technological catch‐up considering spatial and sectoral aggregation of industries. We investigate how geographical and technological proximity to the technology leader impact regional employment growth. We model technological progress by means of a hierarchical process of catch‐up to the technology leader. We also incorporate measures for knowledge spillover effects to test the roles of competition, specialisation, and diversity at the industry level. Empirical results using data at the county level for different economic sectors (2‐dig NAICS) for the United States indicate that human capital plays a crucial role in promoting sectoral employment growth. The association between technological/geographical distance to the technology leader and employment growth varies across sectors.

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.

Reducing Carbon Dioxide Emissions in Australia: A Minimum Disruption Approach

Abstract
While at the Toronto Conference in 1988, Australia adopted a target of reducing carbon dioxide emissions by 20 per cent of 1988 levels by the year 2005, however action to reduce emissions has been negligible. Unilateral action is deemed too costly in terms of the negative effects it could have on employment, GDP growth, exports and international competitiveness .
Most Australian studies have evaluated the effect on such variables of employing a specified policy instrument, such as a carbon tax, to reduce emissions. This study instead uses an input-output method developed by Proops, Faber and Wagenhals (1993) to ascertain the minimum set of changes necessary in different sectors of the economy required to achieve the Toronto Target, where constraints on key macroeconomic variables, such as GDP growth and the level of employment, are met. The cost of reducing emissions is defined here in terms of the required structural changes, when factors like GDP growth are held positive .
The results suggest that the necessary changes in various sectors under each of the scenarios are not far removed from the observed rates of change for Australia. The results are also consistent with those obtained for both Germany and the United Kingdom .

Efficiency and technical progress: sources of convergence in the Spanish regions

The paper analyses the contribution of efficiency as a mechanism of labour productivity convergence, taking as the unit of analysis the Spanish regions in the period 1964–1993. Using the stochastic frontier approach, a translogarithmic production function is estimated for the different sectors of the Spanish regional economy, demonstrating on this basis the existence of substantial differences in efficiency between sectors as well as between regions. With regard to convergence, the results obtained indicate that at aggregate level the convergence observed in labour productivity is explained by the faster growth of the capital-labour ratio of the initially poorer regions and the contribution of technical change and the efficiency, hence by the convergence of TFP. However, the information by sectors shows different results. Thus, on the one hand, the importance of the convergence in production per employee is seen in all sectors except agriculture and, on the other it is observed that technical change is a factor of convergence in all sectors but construction, and, qualitatively, the contribution of technical change is greater than the contribution of efficiency. By sectors, technical change contributed significantly to labour productivity convergence in agriculture, but the faster growth of the capital-labour ratio of the rich regions acted as a mechanism of divergence, completely counteracting the technological catching-up effect. It is further concluded that, as well as the contribution of the accumulation of factors, the positive evolution of efficiency in the poorest regions favoured convergence in the construction and industry sectors, whereas technical progress was decisive in industry and the services sectors.     

Energy conservation,emission reduction and win–win development of China’s industry: 2013–2050 – MDI analysis framework based on directional distance function

As the biggest developing country, China faces the heavy pressure of energy conservation and emission reduction (ECER). China’s industry takes first place in energy consumption and pollution emission among the industrial entities. How to get rid of China’s industrial stagnant growth under the restriction of resources and environment, and find out the optimal path between ECER and industrial development is the main task of this study. The article adopts the historical data of China’s industry from 2003 to 2012, establishes a managerial disposability intensity analysis framework based on the directional distance function, and designs four energy conservation scenarios and nine CO₂ emission paths for a total of 36 kinds of alternative policy combinations to predict the win–win development and find the optimal path of industrial ECER from 2013 to 2050. Research shows that on the whole, industry will fail to achieve a win–win development in the future, while 6% growth rate of industrial output, 2.8% growth rate of energy consumption, and the peak of CO₂ in 2040 is the most optimum path. At the same time, the feedbacks of ECER constraints on specific industrial sectors are different, there are 16 industrial sectors that can achieve win–win development in the future.

Structural change,specialization and regional labour market performance: evidence for the UK

While structural change and regional differences in the pattern of employment specialization are widely perceived to be significant factors in accounting for disparities in the labour market performance of regions in the United Kingdom, there have been relatively few recent attempts to gather detailed evidence on this issue. The current study aims to fill this gap by examining the effects of structural change and associated changes in the pattern of employment specialization on three key indicators of regional labour market performance: the rate of employment growth, the unemployment rate and the rate of nonemployment. The findings indicate that while industry structure has statistically significant effects on regional labour market performance, the quantitative significance of these effects is relatively small.     

我国垄断行业收入与经济增长关系的实证研究——基于面板协整理论

基于1990—2008年我国垄断行业收入的面板数据,通过面板协整、Engle-Granger检验以及运用误差修正模型对我国垄断行业的收入水平与经济增长的长期关系进行分析。研究结果显示:与能源、交通相关的垄断行业的收入与经济增长之间存在长期稳定的协整关系;与能源相关的垄断行业的收入对经济增长具有正向影响,而与交通相关的垄断行业的收入对经济增长的影响不太显著;金融保险业和房地产业的收入与经济增长之间并不存在长期稳定的面板协整关系。     

流通产业发展影响区域经济增长的经验分析

利用1978—2009年我国31个省(自治区、直辖市)的数据,通过对面板数据进行单位根检验、协整检验并利用误差修正模型,考察了我国不同省市的流通产业对区域经济增长的影响。协整检验结果表明:区域流通产业发展与区域经济增长之间存在长期均衡关系,区域流通产业的发展能显著促进区域经济增长,但这种影响存在明显的地区差异,流通产业对中部地区经济增长的贡献要弱于其对东、西部地区的贡献。基于误差修正模型的实证结果表明:在天津、湖南、贵州等11个省(自治区、直辖市),误差修正机制显著发生,其流通产业发展与经济增长存在长期和短期的因果关系;在海南和重庆,误差修正机制发生,但两者仅存在长期因果关系;在北京、山西等11个省(自治区、直辖市),误差修正机制的作用较弱,两者之间的长期因果关系不明显,但短期因果关系显著;在辽宁、江苏等7个省(自治区、直辖市),误差修正机制尚未发生,两者间不存在长期因果关系,仅存在短期因果关系。     

去工业化、经济增长与区域协调发展——基于土地资源错配的视角

针对我国近年来的“去工业化”现象，本文通过280座城市的面板数据，以及城市地形和省级审批建设用地占比构造的工具变量，从土地资源错配视角考察了去工业化对经济增长和区域协调发展的影响。实证结果发现，在当前经济发展阶段工业化对经济增长仍然具有显著的积极影响，过快、过早地去工业化不利于保持经济持续增长和实现区域协调发展，而土地资源在地区间和部门间的双重错配是导致我国出现过早去工业化的重要原因。进一步的分析表明，较高的城镇化水平以及发达的生产性服务业有助于增强工业化对经济增长的推动效应。本文为新时期保持制造业比重基本稳定，推动我国经济持续稳定增长，推进区域协调发展以及促进土地资源优化配置提供了经验证据。     

The impact of pre-announced day-to-day interventions on the Colombian exchange rate

Using cross-country cross-industry data, this paper explores how industry’s growth in number of firms in Central-East Europe (CEE) region is influenced by bank concentration in both the pre-crisis and crisis periods. The CEE region shows highly concentrated banking markets and less-developed financial markets; thus, the level of bank concentration and the resulting credit supply are crucial for firm creation and survival. Despite this, there is little evidence on these countries in the literature. Our empirical results suggest an inverted-U relationship: industry growth is fostered by bank concentration, but there is a turning point from which higher concentration begins producing the opposite effect. Moreover, the positive impact has a greater intensity during the crisis period compared to the pre-crisis period. Between sectors’ analysis shows that high-tech sectors are less reactive to changes in the concentration level.     

Sources of output change in China: 1987-1997: application of a structural decomposition analysis

Since the beginning of the economic reforms implemented in the industrial sectors of China, the economy has grown and changed rapidly. The high GDP growth rates recorded since 1985 have stimulated unprecedented changes in the economic structure of this developing economy. The major causes of the changes are: the increase in consumption and investment, production technological change and trade. The objective was to analyse this type of structural change, and to explore the sources of economic growth during the period 1987–1997, by using the method of structural decomposition analysis (SDA). The chosen SDA method, based on the comparison between two input-output tables, allowed us to decompose each sector's and industry's output growth; it enabled the relative impact of final demand and technological change of each industry on overall growthto be measured.     

前沿技术、吸收能力与中国区域 产业的协同发展*

本文以新增长理论为基础,构建了区域产业与前沿技术差距、区域产业自身发展条件和前沿技术吸收能力的整合空间面板实证分析框架,量化分析了前沿技术、吸收能力和空间外部性引致的产业全要素生产率的收敛机制。研究结论表明：区域产业与前沿技术的差距对于产业的全要素生产率收敛具有显著的促进效应,在短期体现为能够显著的促进区域全要素生产率的增长,长期则表现为存在长期协整关系;前沿技术的吸收能力能够显著地提高全要素生产率;空间溢出效应则进一步强化了这一效应。因此,提升区域产业自身对前沿技术的吸收能力,合理协调区域基础设施、研发创新等空间发展规划,是实现中国区域产业协同发展的有效途径,也有助于实现区域经济协调发展的宏观目标。
