FDI对我国产业内结构优化和产业间结构升级的影响分析

本文利用Granger因果关系检验法实证检验了近年来FDI流入与我国产业结构变动的关系,建立相关指标衡量了FDI对我国产业内结构优化和产业间结构升级的影响,结果表明FDI在我国存在产业结构效应,对第二产业的产业内结构优化有显著作用,但对产业间结构升级的作用不显著。最后,本文给出了利用FDI促进我国产业内结构优化和产业间结构升级的相关政策建议。

南昌地区产业结构的优化路径分析

产业结构合理化是经济的跨越式发展的基础和关键。产业结构有产业间结构、产业内结构之分。运用产业发展与空间布局理论,对南昌地区产业结构的现状及其存在的问题进行剖析,结论是我们应从打破行业垄断、提高城市化水平、促进产业间的有机融合等角度来调整产业间结构,从提高技术研发水平和创新能力、加强特色产业的发展等角度来调整产业内结构,以此来促进南昌地区经济快速崛起并提供理论支持。

产业结构对广东能源利用效率影响的实证分析

广东服务业比重与能源利用效率均高于相近发展水平省份,但产业结构对能源利用效率的影响度却低于后者,原因在于广东产业结构呈现"固化"态势,近十年来升级缓慢——服务业比重上升滞缓。实证分析证明,产业结构,无论是三大产业间结构,还是产业内结构——工业与服务业的内部结构,均是影响广东能源利用效率的关键因素,较之技术进步与能源价格更为重要。因此,亟需优化升级广东三大产业结构,加快发展服务业;还需优化广东工业与服务业的内部结构,着力发展资本技术型工业、知识技术型服务业、消费资料型服务业与公共服务业。唯有抓住关键因素产业结构优化,才能迅速有效提升广东能源利用效率,并能加快广东经济结构转型与升级。

农村劳动力就业转移中的结构问题及对策分析

近年来,随着“三农问题”引起人们的普遍关注,农村劳动力的就业转移也日益被重视。但在农村劳动力转移的实践中,最为棘手的是如何解决就业转移中的结构失衡问题,这就要求我们从战略高度上对其予以高度关注,从理论研讨中寻求相关对策,以切实解决好“三农”问题,使农民摆脱贫困,实现国民经济的协调发展。

Study on the causes and countermeasures for the dislocation of industrial structure in Three Gorges Region

In this paper, the dislocation of industrial structure refers to the inconsisency benveen employment structure and output structure in three industrles. Dnring the past over ten years, with the development of the Three Gorges regional social and economic, the industrial structure has optimized and upgraded constantly. However, for kinds of reasons, employment structure transference has lagged far behind output structure transference. In This paper, we try to analyze the causes of dislocation of the Three Gorges Regional industrial structure in analytical method of dislocation of industrial structure, and put forward the fundamental measures to optimize industrial stracture and promote sustainable development of the regional economy.

The Economic Effect of Mineral Resources Exploitation in Bijie Prefecture in Guizhou

The exploitation of mineral resources plays an important role in promoting national economic development. Mining is an essential component of China's industrial economy. Using grey correlation method to analyze the correlative effect of mineral resources exploitation to relevant industries, using national income method to calculate the pulling effect of mineral resources exploitation to economic growth and using graphs as well as tables to analyze the income distribution effect, the article obtains active economic effect of mineral resources development in Bijie, Guizhou. Moreover, from the view of resources-cored effect, the article analyzes negative effects such as single industrial structure brought by mineral resource development. Through analysis, we find that mineral resources exploitation to some extent brings active effects including gross domestic product growth, local financial revenue growth and relevant industries development; however, its negative effects should not be ignored. The negative effect can be lightened by diversifying industrial structure and prolonging industrial chain.

Protection of Innovative Achievements,Spatial Spillover,and Internal Structural Upgrading of the Productive Service Industry-Empirical Evidence from 28 Provinces in China

This study measured the level of innovation achievement protection and the degree of internal structural upgrading of the productive service industry in 28 provinces of China from 2000 to 2022.Exploratory spatial analysis methods were used to test the spatial correlation between the two variables,and the spatial impact of innovation achievement protection on the optimization of the internal structure of the productive service industry was examined at the national and sectoral levels.The results showed three main aspects of this system.(1)The agglomeration level of innovation achievement protection and internal structure optimization of the productive service industry between regions in China continued to increase during the sample period,and there was a clear similarity and synchronicity in the spatial evolution of the two variables.(2)The overall improvement in the protection level of innovative achievements is conducive to promoting the internal structural upgrading of China’s productive service industry.However,there are significant differences in the degree to which the protection of innovative achievements affects the internal structural upgrading of the productive service industry in the four major regions of the East,Central,Northeast,and West.The protection of innovative achievements in the East and Central regions significantly promotes the internal structural optimization of the productive service industry,while this effect is not significant in the western and northeastern regions.(3)The results of the robustness test indicate that the impact of internal structural upgrading of the productive service industry in the previous year on the level of innovation achievement protection is not significant.The interference from abnormal values of the internal structural upgrading of the productive service industry in various regions and the influence of municipalities directly under the central government on the regression results are not significant.After replacing the main variable,the coefficient of the innovation achievement protection level remained significantly positive.The conclusions of this study supplement and improve the theory of innovation achievement protection and industrial transformation and upgrading,providing decision-making support for improving the level of innovation achievement protection and promoting the internal structural upgrading of the productive service industries in China.
