FDI技术溢出效应的门限特征研究——来自中国省际面板数据的证据

已有的关于FDI(对外直接投资)技术溢出效应研究文献中,大多数学者认为FDI技术溢出会显著地促进东道主国家的经济增长,然而,利用中国1997年-2009年的省际面板数据,对FDI技术溢出效应进行研究却发现,FDI技术溢出效应在中国不同的地区存在显著差异;运用门限回归模型,从地区经济发展水平、地区开放程度、地区人力资本存量、地区金融发展程度等四个方面检验了FDI技术溢出效应的门限特征,并测算出了引发积极FDI技术外溢效应的门限水平。     

金融发展、FDI与经济增长

本文基于拉姆齐—卡斯—库普曼斯模型,利用中国29个省、市、自治区1978～2004年的面板数据,研究金融发展、外商直接投资(FDI)对经济增长的影响。研究显示FDI在一定水平下,对东道国资本积累和产出增长的影响是非线性的,随着外资数量的逐渐增加,其对资本积累和产出增长的促进效应逐渐下降,FDI进入初期的正影响最终转为负影响,研究还显示FDI在数量一定的情况下,金融发展对本国资本积累和产出增长有正影响。金融发展通过有利于吸引外商直接投资、为外资企业提供金融服务,将潜在的溢出效应转化为现实生产力,显著地促进了经济增长。     

Do constraints created by economic growth targets benefit sustainable development? Evidence from China

An economic growth target is a declaration by policy authorities of commitment to that target and the corresponding allocation of resources. The constraints created by economic growth target are an important economic management method in China, which has helped China's economy to achieve remarkable achievements. However, it has also brought about serious environmental problems, threatening China's sustainable development. Using the data about economic growth targets in the work reports of 30 Chinese provincial governments from 2006 to 2017, this paper constructs several spatial measurement methods, such as the spatial Durbin model, to examine the constraints created by economic growth target's impacts on air pollution. The main conclusions are as follows. First, a significant “U-shaped” relationship exists between the constraints created by economic growth targets and air pollution. Second, the spatial Durbin model analysis revealed that PM_2.5 across China's provinces display significant positive spatial spillover effects and spatial agglomeration characteristics. Third, the direct, indirect, and total effects of constraints created by economic growth targets on air pollution are all statistically significant and depict a “U shape.” Finally, the constraints created by economic growth targets have an apparent threshold effect on air pollution, and the inhibiting effects increase with human capital and industrial restructuring. However, with the increase in foreign direct investments, constraints created by economic growth targets may increase air pollution. The conclusions of this paper are of great significance for improving the management of local government economic growth targets and sustainable development.     

环境规制与经济增长关系再研究——基于半参数空间模型

论文采用2005-2017年我国30个省份的面板数据,考虑经济增长的溢出效应,利用空间杜宾模型和半参数空间杜宾模型研究环境规制与经济增长的关系。结果表明:第一,中国经济增长存在显著的正空间相关性,在普通参数模型和空间杜宾模型中环境规制对经济增长的影响不显著。第二,半参数空间杜宾模型的拟合优度高于空间杜宾模型,同时,环境规制与经济增长存在显著的非线性关系。     

公共服务供给、空间溢出与新型城镇化发展质量

本文利用省级面板数据实证研究了公共服务供给对新型城镇化发展质量的作用机理及其空间效应。研究结果表明,公共服务供给和新型城镇化发展质量存在显著的空间相关性,且公共服务供给对新型城镇化发展质量的空间溢出效应日趋增强。教育具有显著的正向空间溢出作用,交通基础设施的空间溢出效应为负但并不显著,医疗具有较为明显的空间抑制作用。进一步进行区域异质性分析发现,公共服务供给对新型城镇化的直接效应和空间效应在三大地区存在明显的差异性。因此,不同区域要基于公共服务供给及其空间溢出效应的特点制定新型城镇化高质量发展政策措施,包括优化公共交通基础设施服务功能、提高人力资源配置效率、改善区域性医疗卫生条件等。     

中国农村金融集聚对农民消费影响的空间效应研究

研究目标:从空间维度考察农村金融集聚对农民消费的影响。研究方法:利用2009～2018年30个省份和四大区域的面板数据,构建空间杜宾模型,估计金融集聚的空间效应,即特定地区农民消费如何关联于本地区和邻近地区的金融集聚。研究发现:在全国省级层面上,农民消费不仅受本省农村金融集聚的显著影响,同时还受到邻近省份空间溢出的显著影响。分区域检验显示,一方面,东部和东北部地区农民消费受到域内金融集聚的影响显著,而中、西部地区则不显著。这一区域差异与农民收入对农民消费的影响具有一致性,但农民收入影响更大。另一方面,中部、西部和东北地区的农民消费受邻近区域金融集聚溢出效应的影响显著,但东部地区则不显著。研究表明,一是农村金融发展对农民消费具有重要影响,二是农民收入过低会弱化金融发展对消费促进效应,增加农民收入是提升消费的根本;三是加强落后地区与发达地区金融合作有利于实现共赢。研究创新:将空间效应引入农村金融集聚对农民消费影响的研究,探究了该影响的空间特征及关联性。研究价值:对农村金融集聚的消费促进效应做出了更全面的评价,为发挥农村金融促进农民消费的政策制定和实施提供抓手。     

基础设施投资的空间溢出效应分析——以沪昆线沿线城市为例

以沪昆铁路沿线区域及城市经济发展为分析对象,实证分析了我国基础设施投资的空间溢出效应。认为沪昆线的基础设施投资既产生了提高沿线区域及城市的运输能力、扩大沿线贸易量、调整沿线产业结构、促进沿线经济增长的空间正溢出效应,也产生了加剧沿线地区及城市要素的非均衡流动、非均衡经济增长的空间负溢出效应。     

地方政府竞争对治理效率的影响——基于Tobit空间杜宾模型的计量分析

基于政府治理提质增效的现实需要,选取2007—2019年中国30个省区市的面板数据,运用DEA效率测度方法并构建Tobit空间杜宾模型检验地方政府竞争对治理效率的影响。研究发现：多数省份政府治理效率未达到效率前沿面,存在提升空间;本地区效率改进能够给周边地区带来正向溢出效应;政府间竞争对治理效率及溢出具有先促进后抑制的倒“U”型影响,防范政府间竞争对治理效率的抑制效应是政府未来治理的重点,其中,法制环境具有负向调节作用,环境越优越,倒“U”型曲线越为平缓,更有利于激发效率改进和溢出。进一步的异质性分析发现,在政府干预程度高和要素市场发育程度低的地区,尽管政府竞争对治理效率的倒“U”型影响不变,但对溢出的影响变为不显著。     

金融发展、FDI技术溢出与中国经济增长——基于省际面板数据的实证分析

基于1990年-2008年中国省际面板数据,就金融发展水平决定的FDI溢出效应对中国经济增长影响的实证研究表明,样本期内FDI通过其资本积累效应,对中国经济增长产生了显著的促进作用,且这一作用有随时间而强化的趋势;金融发展具有放大FDI技术溢出效应的作用,并由此对中国经济增长产生正面影响,但目前来看这一影响还比较小;"金融抑制"现象依然存在并对中国经济增长产生了不利影响,但在经历了多年的金融体制改革之后,"金融抑制"现象已有所减轻,其对经济增长的负面影响趋于减弱。     

中国社会服务的空间格局演变及影响机制

基于地理信息系统技术,引入重心模型、空间自相关指数和不均衡指数,分析了近40年以来中国社会服务总体水平的重心轨迹,揭示了其分布格局及均衡性的演变,并探讨了影响机制。结果显示:中国社会服务的重心经历了三次较大的变迁,空间格局没有显著的省域关联性;空间格局在年份之间存在较大的变异,但均衡性随时间推移显著提高。此外,社会服务的时空演变主要受国家宏观政策、省域经济发展水平和人口分布的影响;均衡性则受国家财政转移支付和省域社会经济发展水平的影响。     

The effects of financial openness and financial efficiency on Chinese macroeconomic volatilities

This paper builds an open-economy DSGE model to study the effects of financial openness and financial efficiency on the macroeconomic volatilities and estimate the model with the Bayesian method and Chinese quarterly data from 2001Q1 to 2017Q4. We further test the validity of model predictions with panel analyses of Chinese provincial data from 1987 to 2016 and various robustness tests. The results show that: first, further financial openness will lead to an increase in output volatility but U-shaped changes in consumption and investment volatilities. Second, financial efficiency improvement helps to reduce the macroeconomic volatilities but has a diminishing marginal benefit. Third, our estimates of China's degree of financial openness and financial efficiency are both at the medium level close to the thresholds. It implies that further financial openness will dramatically increase the macroeconomic volatilities but whether financial efficiency improvement can mitigate instability is uncertain.     

FDI对减贫效应的实证研究

以金融发展为门槛变量，采用我国31个省区市2001—2015年的省级面板数据，运用静态面板数据门槛模型，研究外商直接投资（FDI）与减贫之间的非线性关系。研究结果表明：（1）在不同金融发展水平下，FDI对减贫效应的影响是不一样的，存在双重门槛效应，当金融发展水平较低时，FDI与减贫呈现正相关关系；当金融发展水平较高时，FDI与减贫呈现负相关关系。（2）这种非线性关系在不同区域表现形式也不同，东部门槛值高于中部，西部不存在门槛效应；西部FDI对减贫的作用高于东部和中部。     

Financial development and governance: A panel data analysis incorporating cross-sectional dependence

This study investigates bidirectional causality between governance and financial development using panel data of 101 countries from 1984 to 2013. The financial development–governance nexus is explored using econometric methods robust to cross-sectional dependence, and the relationship between different levels of development and openness is analyzed. Long-run equation estimates show clear evidence that financial development positively affects governance, and this positive impact is found to be robust to three different measures of governance. Further analysis shows that improving governance quality has a positive effect on financial development, while Granger causality tests demonstrate bidirectional causality between financial development and the governance measures. Finally, the impact of financial development on governance is dependent on a country’s level of development and openness. These findings underscore the crucial role of financial development in bringing about good governance reforms and economic growth that, in turn, can further develop the financial sector. As such, a symbiotic and synergistic relationship can persist between good governance, growth, and financial development. The findings provide significant motivation for policymakers to encourage openness and financial sector development to lift the standard of living, especially in emerging economies.     

中国绿色发展的空间网络结构研究

利用中国30个省份(不含西藏和港澳台地区)的2016年绿色发展指数,构建修正引力模型,采用社会网络分析方法对中国绿色发展的空间网络结构特征进行的研究发现:2008—2016年中国绿色发展水平提升显著,地区间差异在缩小但差异仍较为明显,且地区间的联系突破地理邻近效应,呈现为广泛复杂的网络关联和结构形态并趋于稳定。绿色发展空间分布呈现:以环渤海为主的“双向溢出”板块,主要体现出经济及技术外溢以及能源输入;以西南地区为主的“双向溢出”板块主要进行资源供给及接受技术外溢;以东部沿海省份为主的“主受益”板块,体现其绿色发展得益于西北及环渤海地区的资源供给,各指标水平较高且均衡,但板块外的溢出效应不明显;西北地区省份为主的“净溢出”板块,各方面发展均比较落后,主要对环渤海地区进行资源供给;陕西、河南作为资源密集型省份,其绿色发展受自身经济、产业结构等因素的限制,但因其地理位置居中,处于网络中心性最高的重要地位,与其他省份存在较广泛密切的联系,建议培育为新的绿色发展增长极;总体上,板块内部聚类明显,但仍存在板块内部分省份及板块间的互动不强,需打破行政壁垒,发挥自身优势,促进板块间的技术、人才交流及资金流动,实现绿色协同发展。     

制造业聚集、知识溢出与区域创新绩效——以我国医药、电子及通讯设备制造业为例的实证研究

本文的目的是探讨制造业生产行为聚集所产生的各类知识溢出对区域创新绩效的影响。这些溢出包括知识的专业化溢出、多样化溢出和空间溢出。对我国医药、电子及通讯设备制造业实证分析的结果显示,知识的专业化溢出对两类制造业的区域创新存在积极影响;多样化溢出对医药制造业区域创新绩效的影响为正,对电子及通讯设备制造业的影响为负。实证结果表明,各类知识溢出对区域创新绩效的影响存在行业间差异和国家间差异。     

中国城市化与经济增长的省际差异分析

采用聚类分析方法、相关分析方法和回归分析方法,对我国省际城市化水平与经济增长水平的差异进行定量分析,得出以下结论:总体来看,经济发展水平与城市化水平有着较密切的正相关关系;个别地区(如广东)的经济发展水平并不完全与城市化发展水平相适应,经济的发展是由其他因素促成的;天津的城市化水平已经接近极限,而北京和上海的城市化水平仍然有进一步发展的空间;对于落后地区来说,发展经济的重要性更重于狂热地进行城市化.     

Spatial spillover effects and risk contagion around G20 stock markets based on volatility network

Employing the spatial econometric model as well as the complex network theory, this study investigates the spatial spillovers of volatility among G20 stock markets and explores the influential factors of financial risk. To achieve this objective, we use GARCH-BEKK model to construct the volatility network of G20 stock markets, and calculate the Bonacich centrality to capture the most active and influential nodes. Finally, we innovatively use the volatility network matrix as spatial weight matrix and establish spatial Durbin model to measure the direct and spatial spillover effects. We highlight several key observations: there are significant spatial spillover effects in global stock markets; volatility spillover network exists aggregation effects, hierarchical structure and dynamic evolution features; the risk contagion capability of traditional financial power countries falls, while that of “financial small countries” rises; stock market volatility, government debt and inflation are positively correlated with systemic risk, while current account and macroeconomic performance are negatively correlated; the indirect spillover effects of all explanatory variables on systemic risk are greater than the direct spillover effects.     

政府干预与食品产业发展效率 ——基于地方政府竞争视角

本文基于地方政府竞争视角,选取2005—2015年省级面板数据,测度中国省级食品产业发展效率,并通过实证分析揭示政府干预对食品产业发展效率的影响及其空间溢出效应.研究结果表明:中国整体食品产业发展效率在样本期内仍处于较低水平,且具有显著的空间非均衡特征.在不考虑地方政府竞争时,政府干预对食品产业发展效率具有抑制作用;考虑地方政府竞争后,政府干预不仅负向影响本地区食品产业发展效率,而且对邻近地区食品产业发展效率具有负向的空间溢出效应.这表明现阶段应注重政府监管模式改革,坚持监管投入增加与监管质量提升并举,同时推动治理模式多元化.     

Nonlinear impact of the interaction between internal knowledge and knowledge spillover on patent quality: Evidence from China's provincial high-tech industry

This paper first divides knowledge resources into internal knowledge and knowledge spillover from the dual perspective of inside and outside the region. Then, a panel threshold regression model is constructed by using the panel data from 30 provincial high-tech industries in China during the 2009–2019 period using the intellectual property protection intensity as the threshold variable, and the nonlinear impact of the interaction between internal knowledge and knowledge spillover on the patent quality in the high-tech industry is empirically explored. The results show the following. (1) The interaction between internal knowledge and knowledge spillover has a significant nonlinear effect on the patent quality in China's provincial high-tech industry. There is a double-threshold effect with the intellectual property protection intensity as the threshold variable. (2) As the threshold value of the intellectual property protection intensity increases, the promotion effect of the interaction between internal knowledge and knowledge spillover on the patent quality first increases and then decreases. (3) The spatiotemporal heterogeneity of the intellectual property protection intensity is obvious in all regions in China. (4) Internal knowledge, the infrastructure construction level, and the human capital level have significant positive effects on the patent quality, while knowledge spillover and the opening-up level have significant negative effects.     

回弹效应加剧了中国能源消耗总量的攀升吗？

基于29个省份1995~2011年能源平衡表核算出各省份生产性能源消耗总量,构建考虑地区经济空间溢出以及能源—经济非线性关系的面板数据半参数空间滞后模型,在测算各省份历年能源产出弹性的基础上对技术进步导致的能源消耗回弹效应进行了估计,考察回弹效应对能源消耗总量攀升的影响。研究发现,中国能源消耗回弹效应具有明显的时空特征,并非所有年份均会出现回弹效应,回弹效应相对集中出现在东部省份,而经济欠发达省份回弹效应难以呈现;大部分省份所出现的回弹效应主要集中在2001年以前;能源消耗总量攀升并非是回弹效应所致,乃是由于技术水平和经济增长质量低下造成的。
