This article has constructed a framework to analyze the relationship between national innovation investments, international knowledge spillover due to FDI and regional technological progress. We use the panel data sample in 1992–2006 from China’s 29 provinces (municipalities or autonomous regions) to test the impact of China’s regional R&;D investments, international knowledge spillovers of FDI on its regional technological progress. It reveals that the local investments in science and technology are the most important factors to promote technological progress; for the structure and quality of China’s current FDI, the knowledge spillover effects from FDI, especially through the FDI enterprises’ manufacturing activities, are not obvious; the local gains in its technology development from FDI depends on its economic and technological level. Based on the above conclusions we give the corresponding policy recommendations for China’s FDI policy and regional economic development.  相似文献

We in this paper assess the impacts of technological change on China's regional disparities using a general equilibrium model of multiple regions and multiple sectors. We use the most recent available Chinese interregional data to calibrate the model parameters for 1987 and 2000. We then assess the impacts of neutral, biased, and aggregate technological changes on China's regional disparity by conducting counterfactual experiments. The results generally suggest that China's overall technological change between 1987 and 2000 has increased China's regional disparities. The results also suggest that neutral technological change reduces China's regional disparities while biased technological change increases disparities and the influences of the latter outweigh those of the former and the net effects of technological changes on regional disparities are increasing.  相似文献

This study, which considers both energy input and CO2 emissions, develops both theoretical and empirical models to account for the sources of China's economic growth from 2000–2013. The proposed models decompose China's economic growth into five components: the technological change effect, the industrial structure effect, the regional balance development effect, the management effect, and the production factors effect. The empirical results show that during the sample period, the production factors effect increased from approximately 70% in 2001 to nearly 99% in 2010, indicating that economic growth in Mainland China relied heavily on factor accumulation, which was not sustainable. Fortunately, this situation has gradually improved since 2011 because of technological progress and industrial structure optimization. However, the current total-factor productivity in Mainland China remains relatively low because of an inefficient industrial structure, regional balance development, and management inefficiency. In other words, there is a great deal of room for further industrial structural optimization, regional balance development, and management improvement to realize further sustainable economic growth. Because the causes of total-factor production inefficiency and the distribution of economic growth potential show a distinct spatial difference, the focuses for the Chinese provinces to achieve sustainable economic growth should be quite different in the future. Based on the results of this study, recommendations have been made for the Chinese provinces to realize further sustainable economic growth.  相似文献

Applying the multiple indicators and multiple causes (MIMIC) approach, the present paper measured the size of the shadow economies in China's provinces over 1995–2016. The results show that the average size of the shadow economy in 30 provinces of China increased from 13.55% in 1995 to 14.39% in 2009, and then decreased to 12.30% in 2016. There are obvious variations in the size of the shadow economies in different districts of China. The average size of the shadow economy is lowest in provinces in the eastern district and highest in the western district. In addition, the causes and consequences of the shadow economies in China's provinces have also been analysed using the MIMIC approach, and the results show that tax burden, complexity of the tax system, intensity of regulation, unemployment, employment in the agricultural sector and economic openness have significant positive effects on China's shadow economy, while the ratio of direct taxes to indirect taxes, fiscal autonomy and income levels have significant negative effects on China's shadow economy. Using the growth rate of energy consumption as the benchmark indicator, the MIMIC analysis shows that the shadow economy has significant positive effects on the development of the official economy and income inequality while having a significant negative effect on the labour participation rate.  相似文献

This paper focuses on the relationship between the world oil price and China's coke price, particularly with respect to extreme movements in the world oil price. Based on a daily sample from 2009 to 2015 and the ARJI-GARCH models and copulas, our empirical results show that China's coke price and the world oil price are characterized by GARCH volatility and jump behaviors. Specifically, negative oil price shocks lead to falls in China's coke returns on the following day while positive oil prices have no significant effects. In addition, current coke returns positively respond to the very recent oil price jump intensity, and a time-varying and volatile lower tail dependence is found between the world oil price and China's coke price. Our results are expected to have implications for coke producers and users and policy makers.  相似文献

This study examines how trade-related spillovers impact the OECD countries' industrial competitiveness; with an emphasis on China's innovative efforts and reintegration into the global economy. In comparison with the major R&D countries, benefits attributable to spillovers are found to be more sizable for the rest of the OECD countries.This result is consistent with the observed convergence of competitiveness between the two groups of countries during 1990–2009.Moreover, our empirical results suggest China's trade-related spillovers can produce both positive and negative effects on OECD countries' industrial competitiveness. The persistence of the spillover effects is found even after controlling for trade openness creating possible spurious association. Finally, our finding TFP growth as the competitiveness driver stresses the consequential role of STI (science, technology, and innovation) policies in supporting sustainable and balanced growth.  相似文献

This paper tests the external spillover effects of the transportation on China’s economic growth from the theoretical and the empirical perspectives. Based on a logarithm production model, this study first proves the existence of the positive externality in the transportation. After that, the authors collect the data of the 28 provinces in China from 1985 to 2006, and use a relatively advanced spatial econometric method to test the positive externality. After constructing a spatial econometric model, the authors use the Maximum Likelihood (ML) method to estimate this model. According to the theoretical model and the empirical results, this article reaches the following conclusion: (1) The positive externalities in the transportation do exist; (2) From 1985 to 2006, the transportation contributed 24.8 billion yuan to China’s GDP every year: in this 24.8 billion yuan, 19.6 billion comes from the direct contribution and the rest 5.2 billion comes from the external spillover effects; (3) The summation of the direct contribution and the external spillover effects to the economic growth is on average 13.8% every year.  相似文献

China experienced sustainable, rapid economic growth over the period 1980–2003 but, at the same time, energy-related carbon intensity showed a downward trend. It begs the question, therefore, what factors were driving this decline in carbon intensity and will this decline be maintained in future? Moreover, what measures can be adopted to ensure a continual decline in carbon intensity? These questions led to increased research in the factors governing CO2 emission in China. This paper quantifies the driving force behind China's primary energy-related carbon intensity and measures the material production sectors' final energy-related carbon intensity. Our results show that the overwhelming contributor to the decline of energy-related carbon intensity was the reduction in real energy intensity. However, policies that focus only on the decline in energy intensity are insufficient to further decrease carbon intensity. The change of primary energy mix can improve the decline of carbon intensity. This should focus on the material production sectors' development strategies and final energy use. Greater emphasis should be given to secondary industry, which needs national and regional governments' policy support.  相似文献
