关于公共支出与经济增长的国内外研究综述

公共支出与经济增长的关系一直以来为经济学家们所争论。持公共支出促进经济增长观点认为,政府公共支出在经济增长中发挥着重要作用,因为它为经济发展提供了大量的公共品和其他具有外部效应的公共福利或服务,从而鼓励和便利了私人投资,形成了一个较好的投资环境,促进了经济增长。而持反对意见的认为,公共支出往往是生产率较低的,为融通政府支出而形成的高税收又会对私人部门的消费和投资造成很大的负面影响,因此,必须缩减政府支出,才能保证经济增长。当然也有人持两者根本就没有关系的观点。     

Fiscal position and the financing of productive government expenditures: an application to Latin America

Government spending on public infrastructure, education, and health care can increase economic growth. However, the appropriate financing depends on a country’s fiscal position. We develop a two-sector endogenous growth model to explore how variations in the composition and financing of government expenditures affect economic growth. We find that, when tax rates are moderate, funding public investment by raising taxes may increase long-run growth. If existing tax rates are high, public investment is only growth enhancing if funded by restructuring the composition of overall public spending. Additionally, public investment that is debt financed can have adverse effects on long-run growth due to the resulting increases in interest rates and debt-servicing costs.     

地方政府财政支出结构影响农村居民消费的实证研究

地方政府财政支出可划分为投资性支出、消费性支出和福利性支出.通过构建适合我国农村居民消费特征的理论模型,运用1995-2009年省际面板数据,实证检验地方政府财政支出对农村居民消费的影响.结果显示:政府投资性支出和福利性支出对农村居民消费具有正向促进作用,政府消费性支出对农村居民消费则具有负向抑制作用.因此,政府应该进一步优化财政支出结构来促进农村居民消费的增长.     

Government size,composition of public spending and economic growth in Brazil

The performance of the fiscal policy is largely affected by the relationship between government size, composition of public spending and economic growth. We use a theoretical framework to find optimal relations among these variables and confront them with a panel data for the Brazilian states. Private capital and government spending are substitute inputs in production as the Brazilian states require provision of public spending to fill gaps in the underdeveloped private sector. Public investment and current government expenditures are combined in fixed ratios in the overall government spending due to strong rigidity of the public budget. The optimal share of public investment is considerably lower than current expenditures, as occurs in developing countries characterized by low economic dynamism. Finally, the average tax burden from the data is below the estimated optimal level, meaning that there is space for increasing tax rate without harming economic growth for some Brazilian states.     

是何因素制约着中国居民消费

居民消费增长相对缓慢给我国经济的持续健康发展带来挑战,扩大居民消费加快形成消费、投资、出口协调驱动经济增长的新局面是我国经济发展到新阶段后的客观要求。本文基于预防性储蓄理论分别从不确定性、收入分配和公共支出三个视角系统地研究中国居民消费的制约因素。研究分析表明,居民谨慎的消费行为、收入分配的不合理,公共支出转型滞后等都严重地制约着我国居民消费的增长,并据此提出相应的政策建议。     

我国宏观税负的经济影响分析

一国的税收收入来源于经济,宏观税负与经济增长之间存在相互作用,而且这种相互作用不仅是当期的,更有长期的相互影响。因此,在对宏观税负的经济影响研究中,本文运用SVAR模型结合政府支出研究我国宏观税负与经济增长之间的动态关系,即宏观税负的经济增长效应,并使用脉冲响应函数和方差分解这两个工具,对变量之间的传递效应进行数量分析。文章随后还构建了四个SVAR模型,深入分析宏观税负的经济增长作用机制。研究发现,宏观税负通过投资、消费、进口和出口影响经济增长,其中降低宏观税负的刺激作用只有对投资才是长期有效的,宏观税负对消费、进口和出口的影响仅仅是短期显著。而且相比于增加政府支出对经济增长的正效应,降低宏观税负的效果短期不显著且长期不持续。     

Asymmetric output growth effects of government spending: Cross-sectional and panel data evidence

Using a model that accommodates asymmetric adjustments of output growth to changes in growth of government spending, the effects of aggregate and disaggregate government spending variables on output growth are examined. Both cross-section and panel regression estimations are conducted. Robustness of results to joint-endogeneity of output and government spending, alternative conditioning variables, and cointegration is investigated. Aggregate government spending appears to have positive output growth effects particularly in periods of below-trend growth in this variable. The government sector's productivity appears to be higher than non-government sector's productivity when spending growth is below-trend growth and only for non-OECD countries; no differences in sectoral productivities are detected for OECD countries. Government consumption spending has no significant output growth effects, but government investment spending has positive output growth effects particularly when its growth falls below its trend-growth; this favorable effect turns negative when government investment spending growth exceeds its trend-growth. Results are robust across alternative model specifications and estimation methods.     

Public Investment and Economic Growth in Latin America: an Empirical Test

The paper analyzes the impact on economic growth of public investment spending and other relevant variables (such as human capital) for nine major Latin American nations over the 1983–93 period. The results suggest that both public and private investment spending contribute to economic growth. Overall central government consumption expenditures, on the other hand, are found to have a negative effect on private investment and growth. Finally, public expenditures on education and healthcare are found to have a positive and statistically significant effect on private capital formation and long–term economic growth. From a policy standpoint, the results suggest that indiscriminate cuts in public and private investment spending are likely to be counterproductive in the long run, and more importantly, scarce public expenditures should be channeled to the promotion of new human capital (via primary and secondary education) and the maintenance of existing human capital (through healthcare expenditures).     

Functional components of public expenditure,fiscal consolidations,and economic activity

This paper analyses how the functional components of public expenditure and spending‐driven consolidations affect the economic growth, unemployment, and income inequality. A dynamic panel data least squares dummy variable estimator estimator is employed over a sample of 15 European Union countries during the period 1990–2012. The empirical results show that real GDP growth decreases when fiscal austerity measures are implemented, especially if they are spending‐driven. Cuts in public expenditure undermine economic growth, namely if they slash spending on public order, recreation, and education. Spending cuts on education, in particular, affect the investment in human capital, harming not only growth but also economic, social, and human development. The unemployment rate also proved to be significantly boosted when austerity measures restrict spending on education, whereas income inequality rises when social protection expenditures are cut.     

政府支出与私人消费的关系研究——基于跨国数据（1983—2008年）的面板协整分析

文章运用面板协整分析方法和世界上36个国家（20个发达国家和16个发展中国家）1983—2008年的面板数据进行跨国研究,通过建立变系数面板模型并结合可支配收入和宏观经济环境的影响,分析了政府支出和私人消费的关系。研究结果显示,总体上而言,样本国家的政府消费支出与私人消费成互补关系,可支配收入仍然是影响私人消费的主要因素,宏观经济环境（经济开放程度和失业率）对消费的影响在统计上很不显著。为了扩大消费,中国政府应实施积极的财政政策、扩大财政支出和提高社会保障水平以及切实解决民生基本难题。

Disaggregated approach to government spending shocks: a theoretical analysis

We calibrate a dynamic stochastic general equilibrium model that features a transmission mechanism with different types of government spending, while the literature usually treats government spending as a homogenous compound. In this regard, we manage to distinguish between different types of government spending (namely: government investment, government wage component consumption and non-wage component consumption) where each type of spending has a varied role in the economy. The government wage increase has the largest positive effect both on private consumption and output by affecting the economy through the government production. This is a natural consequence of government production being complementary to private consumption in our model. Other two government spending types, namely government non-wage consumption and government investment, also have positive effects on output, whereas their responses on (private) consumption are mostly negative. These results provide an alternative explanation for the wide range of multipliers existing in the literature as our setup enables them to produce different effects on macroeconomic variables.     

Reconsidering Wagner’s law: evidence from the functions of the government

We revisit Wagner’s law by function of government expenditure. Using data of 14 European countries between 1996 and 2013, we apply panel data and SUR methods to assess public expenditure–income elasticities. We find that some functions of government spending for a few countries (e.g. Austria, France, the Netherlands and Portugal) validate Wagner’s law. For the Netherlands, expenditures with environment protection increase more than proportionately to economic growth, and for France that is the case of spending in housing and community amenities. In addition, Greece is the only country where two public spending items react more than one to one to growth.     

On the heterogeneous impact of public capital and current spending on growth across nations

This paper captures the heterogeneous impact on growth, of public capital and current spending, for 15 developing countries. Using the GMM system panel estimator, we show that countries with substantial public capital (current) spending have strong negative (positive) growth effects.     

财政支出结构与经济增长关系研究——基于发达国家的经验研究

笔者对13个发达国家1972年～2006年的面板数据进行了实证研究,结果显示:资本性(经常性)支出对经济增长率有负(正)效应,这与以往许多学者所认为的财政的资本性支出较之经常性支出对经济增长更有贡献的观点是相左的。其次,财政支出规模、私人固定投资以及外汇黑市溢价对经济增长也有着显著的影响。本研究对于在平衡预算下的财政支出结构决策有现实指导意义。     

PUBLIC AND PRIVATE INVESTMENT AND ECONOMIC GROWTH IN MEXICO

This paper analyzes the impact on economic growth of public and private investment spending in Mexico. Public investment expenditures had a positive and significant effect on output growth. Public investment's impact on economic growth was statistically identical to the impact of private capital spending. The contribution of public investment to output expansion came at the expense of private investment as indicating a significant crowding out effect.     

Changes in the fiscal stance and the composition of public spending

We consider the impact of both cyclical and structural changes in the fiscal stance on public spending composition for a panel of EU countries, including individual components of public investment. We find that both cyclically induced and structural changes in the fiscal stance affect the composition of public spending, with fiscal tightening of both types increasing the relative share of investment and loosening favouring consumption expenditure. Of the components of public investment, infrastructure and redistribution respond to cyclical changes in the fiscal stance, while investment in hospitals and schools responds most clearly to structural changes.     

Public spending and growth: The role of government accountability

This paper examines the role of institutions in the nexus between public spending and economic growth. Empirical results based on a newly assembled dataset of 80 countries over the 1970–2010 period suggest that particularly when institutions prompt governments to be accountable to the general citizen does public capital spending promote growth. Taking account of the type of financing for this spending, we show that the growth-promoting effect under an accountable government appears to prevail for various financing sources, including a reallocation from current spending, an increase in revenue, and a rise in the budget deficit. However, government accountability does not seem to play a key role in the growth effects of current spending.     

MILITARY SPENDING,THREATS AND STOCHASTIC GROWTH

This paper analyses the impact of home military spending and foreign military threat on economic growth in a stochastic endogenous growth model involving the supply‐side and demand‐side effects produced by military spending. The paper states that an increase in home military spending affects economic growth through three channels, including the crowding‐out effect, the spin‐off effect, and the resource mobilization effect. The net effect which depends on these three channels is ambiguous. Hence, we demonstrate that there exists an optimal defence burden that maximizes the economic growth rate. Furthermore, the optimal defence burden depends on the degree of risk preference. Namely, the optimal defence burden of the risk‐loving agent is more than that of the risk‐neutral agent, and in turn is more than that of the risk‐averse agent. At the same time, we prove that the relationship between the volatility in military spending and economic growth also depends on the degree of risk preference. In addition, we show that greater volatility in foreign military spending leads to a decrease in home aggregate consumption, and hence speeds up economic growth in the home country.     

Does too much government spending depress the economic development of transition economies? Evidences from dynamic panel threshold analysis

This paper investigates the relationship between government size and economic growth and determines the optimal level of government spending to maximize economic growth. The paper applies a dynamic panel data analysis based upon a threshold model to test the threshold effect of government spending in 26 transition economies over the period spanning 1993–2016. According to the analysis results, government expenditures have a threshold effect on economic growth, and there is a non-linear relationship depicted as an Armey curve in these transition economies. The findings indicate that a government size above the threshold government spending level adversely affects economic growth, while a government size below the threshold level has a positive effect. Furthermore, there is a statistically significant relationship between the two variables above and below that optimal level, even if we divide the sample into developed and developing countries. Our findings suggest that governments in transition economies should consider optimal government size at around the estimated threshold level to support sustainable economic growth.
