Research background: The crisis periods have highlighted the interdependence between individual European economies in the area of economic and fiscal development. The common development tendencies raise the question whether the fiscal indebtedness and preferred fiscal policy of V4 countries can be considered as interdepending. Considering this assumption, a possibility for implementing a similar type of consolidation in selected clusters of countries could be proposed. Purpose of the article: The research is, from the empirical point of view, focused on the analysis and comparison of primary balance indicator, analysis and assessment of fiscal measures (in identified fiscal episodes) and analysis of fiscal development intercorrelations using the dynamic conditional correlation approach. Methods: The empirical assessment of the research objective is, from the methodological point of view, divided into five phases: (1) the calculation of primary deficit indicator, (2) the analysis, comparison and assessment of the fiscal development in the V4 countries based on the annual primary deficit during the selected period 1999–2016, (3) the seasonal adjustment of performing time series and non-stationarity testing, (4) the dynamic conditional correlation approach (DCC) application. Within the analysis, the traditional and specific methods were used (time series analysis, content analysis, descriptive statistics, correlation methods, DCC approach). Findings & Value added: The results of the research suggest that between V4 countries do exist significant differences based on which cannot be clearly confirmed the assumption about the fiscal development interdependence in V4 countries. From the long-term perspective, it can be stated that the fiscal development in V4 countries is a very slightly positively related aspect, but in the context of the implementation of a common consolidation strategy it is not sufficient.
研究背景:危机时期凸显了欧洲各经济体在经济和财政发展领域的相互依存关系。共同的发展趋势提出了一个问题,即V4国家的财政负债和首选财政政策是否可以被视为相互依存。考虑到这一假设,可以提出在选定的国家集群中实施类似类型合并的可能性。本文的目的:从实证的角度出发,重点分析和比较主要平衡指标,分析和评估财政措施(在已确定的财政事件中),并使用动态条件相关方法分析财政发展的相互关系。方法:从方法论的角度来看,对研究目标的实证评估分为五个阶段:(1)主要赤字指标的计算,(2)基于1999-2006年选定时期V4国家的年度主要赤字对财政发展进行分析、比较和评估,(3)执行时间序列和非平稳性测试的季节性调整,(4)动态条件相关方法(DCC)的应用。在分析中,使用了传统和特定的方法(时间序列分析、内容分析、描述性统计、相关性方法、DCC方法)。研究结果与附加值:研究结果表明,V4国家之间确实存在显著差异,在此基础上无法明确证实V4国家财政发展相互依存的假设。从长期角度来看,可以说V4国家的财政发展是一个稍微呈正相关的方面,但在实施共同巩固战略的背景下,这是不够的。

The Forecasts-Based Instrument Rule and Decision Making : How Closely Interlinked? The Case of Sweden 基于预测的工具规则与决策:联系有多紧密?瑞典的案例
IF 5.7 Q1 Economics, Econometrics and Finance Pub Date : 2017-06-30 DOI: 10.24136/EQ.V12I2.16

Research background: The Central Bank of Sweden declared in years 1999–2006 the implementation of the Svensson’s concept of inflation forecast targeting (IFT). It means that the repo rate decision-making process depends on the inflation fore-casts. The concept evolved from the strict IFT with the decision-making algorithm called ‘the rule of thumb’ to the flexible IFT. Purpose of the article: The aim of the article is to: (1) analyze the influence of the inflation rate and GDP growth rate on the repo rate decisions, (2) analyze the influence of the inflation rate and GDP growth rate forecasts (in two year horizon) on the repo rate decisions in Sweden in years 1999–2006. Methods: The analysis encompasses the repo rates decisions, CPI inflation rate, GDP growth rate, central paths of CPI inflation forecasts and central paths of GDP growth rate forecasts (the mode values) in the two years horizon published by The Central Bank of Sweden in years 1999–2006. The studies are based on the Taylor-type instrument rule and forecast-based Taylor-type instrument rule. The methodology used is multiple linear regression models. Findings & Value added: The Central Bank of Sweden in years 1999–2006 implemented direct inflation forecast targeting (DIFT) rule. The decision-making algorithm was based on the CPI inflation forecasts and the rule of the thumb algorithm. The exact rule of the thumb was as follow: if the inflation forecast, in the two year forecast’s horizon exceeded the infla-tion target by 1 p.p., then the central bank raised the repo rate by 0.4 p.p; if it was below it, then the central bank reduced the repo rate by 0.4 p.p. If the inflation forecast was equal to the inflation target, then the repo rate remained unchanged. The historical repo rates differ from the theoretical estimated rule of the thumb’s repo rates by +/-0.28 p.p.
研究背景:瑞典中央银行于1999-2006年宣布实施斯文森的通胀预测目标制(IFT)概念。这意味着回购利率的决策过程取决于通胀预测。这个概念从严格的IFT和称为“经验法则”的决策算法演变为灵活的IFT。本文的目的是:(1)分析通货膨胀率和GDP增长率对回购利率决策的影响,(2)分析通货膨胀率和GDP增长率预测(两年内)对瑞典1999-2006年回购利率决策的影响。方法:对瑞典央行1999-2006年两年期的回购利率决策、CPI通胀率、GDP增长率、CPI通胀预测中心路径和GDP增长率预测中心路径(模式值)进行分析。研究基于泰勒型仪器规则和基于预测的泰勒型仪器规则。使用的方法是多元线性回归模型。瑞典央行在1999-2006年间实施了直接通胀预测目标制(DIFT)规则。决策算法基于CPI通胀预测和经验法则算法。确切的经验法则如下:如果两年内的通胀预测超出通胀目标1个百分点,那么央行将回购利率上调0.4个百分点;如果通胀预期低于目标,则央行将回购利率下调0.4个百分点。如果通胀预期与通胀目标相等,则回购利率保持不变。历史回购利率与理论估计的经验法则回购利率相差+/-0.28个百分点。

THE MULTIFACTORIAL PASTOR-STAMBAUGH MODEL: EXPLAINING THE IMPACT OF LIQUIDITY ON THE RATE OF RETURN BASED ON THE EXAMPLE OF THE WARSAW STOCK EXCHANGE 多因素PASTOR-STAMBAUGH模型&以华沙证券交易所为例解释流动性对收益率的影响

Research background: The liquidity of assets in the financial market is under-stood gener-ally as costs, and the easiest way in which different types of assets can be converted into cash, or to put it simply, sold at the currently available price on the market. For a considerable period of time this category had not been duly considered in the framework of modern finance theory. As a result, a number of basic models constructed within the framework of this theory in its classical form did not include problems with liquidity. This applies to a number of aspects related to liquidity, with one of the most important being the relationship between the liquidity of trading in shares and the results obtained from these rates of return. Purpose of the article: The aim of the article is to determine whether the rate of return on shares increases with the increase in share liquidity and the incremental rate of return on this account decreases with increasing liquidity. The applied re-search methodology is similar to that described by Pastor and Stambaugh (2003). The model used in the empirical study is the expanded model of Fama and Francha (1993) for the liquidity factor. Methods: In this paper I present various factors which will affect the liquidity. The paper will also provide the results of research concerning the relations between spread and stock return on the Warsaw Stock Exchange (WSE). The evidence drawn from WSE stock returns over the period 2004–2012 indicates that Amihuda measure and other variables have a significant effect on stock return using the multifactorial Pastor-Stambaugh. Findings & Value added: In the case of the Polish market, it can be stated that in the analysis based on the Pastor-Stambaugh model not all the variables included in this model are statistically significant. However, directional parameters associated with liquidity risk were statistically significant in all analyzed periods, which allows us to confirm the hypothesis that liquidity has a significant influence on the rate of return on shares listed on the Stock Exchange in Warsaw.
研究背景:金融市场中资产的流动性通常被低估为成本,这是将不同类型的资产转换为现金的最简单方法,或者简单地说,以当前市场上的可用价格出售。在相当长的一段时间里,这一类别没有在现代金融理论的框架内得到适当的考虑。因此,在该理论的框架内以其经典形式构建的一些基本模型不包括流动性问题。这适用于与流动性相关的许多方面,其中最重要的是股票交易的流动性与从这些回报率中获得的结果之间的关系。文章的目的:文章的目的是确定股票回报率是否随着股票流动性的增加而增加,而该账户的增量回报率是否随流动性的提高而降低。应用的重新搜索方法类似于Pastor和Stambaugh(2003)所描述的方法。实证研究中使用的模型是Fama和Francha(1993)对流动性因素的扩展模型。方法:本文提出了影响流动性的各种因素。本文还将提供华沙证券交易所(WSE)价差与股票回报关系的研究结果。从2004年至2012年期间WSE股票回报中得出的证据表明,使用多因素Pastor Stambaugh,Amihuda测度和其他变量对股票回报有显著影响。调查结果和附加值:在波兰市场的情况下,可以说,在基于Pastor Stambaugh模型的分析中,并非该模型中包含的所有变量都具有统计学意义。然而,与流动性风险相关的方向性参数在所有分析期都具有统计学意义,这使我们能够证实流动性对华沙证券交易所上市股票的回报率有重大影响的假设。

Earnings Forecasts Errors In Prospectuses: Evidence From Initial Public Offerings On The Warsaw Stock Exchange 盈利预测与预期错误:来自华沙证券交易所首次公开募股的证据
IF 5.7 Q1 Economics, Econometrics and Finance Pub Date : 2017-06-30 DOI: 10.24136/EQ.V12I2.12

Research background: Several studies investigated the issue of accuracy of earnings fore-casts disclosed in IPO prospectus because of its importance in the investor’s decisions. Disclosing earnings forecasts can reduce information asymmetry and encourage potential investors to buy offered shares. The accuracy of earnings forecasts, and especially its deter-minants, was explored by some researchers, but for Polish companies such studies have not been conducted. Purpose of the article: The first objective of this study is to examine the bias and accuracy of earnings forecasts disclosed in IPO prospectuses by Polish companies attempting to be listed on the main market of the Warsaw Stock Exchange. The second aim of this paper is to identify the relationship between the absolute fore-cast error employed as a measure of earnings accuracy and a number of company specific characteristics such as company’s size, leverage, forecast horizon, managerial ownership, number of shares offered to investors (in relation to total shares before IPO). Methods: The empirical analysis were conducted on a sample of 102 domestic companies that performed IPOs on the main market of the Warsaw Stock Exchange during 2006-2015 and disclosed earnings forecasts in IPO prospectus. The forecast error (FER) and absolute forecast error (AFER) were adopted as a measure of accuracy of earnings forecasts. The non-parametric test was employed to achieve the adopted aims. Findings & Value added: The results show that, on average, the forecasted earnings exceed the actual earnings (i.e. the earnings forecasts are optimistic) and fore-casts are inaccurate. Moreover, the optimistic forecasts are more inaccurate than pessimistic ones. The findings of multiple regression model show that three independent variables may affect the level of absolute forecast error: the company’s size, managerial ownership and forecast horizon.
研究背景:几项研究调查了IPO招股说明书中披露的盈利预测的准确性问题,因为它在投资者的决策中很重要。披露盈利预测可以减少信息不对称,鼓励潜在投资者购买发行的股票。一些研究人员探讨了盈利预测的准确性,尤其是其决定性因素,但波兰公司尚未进行此类研究。本文的目的:本研究的第一个目的是检验试图在华沙证券交易所主要市场上市的波兰公司在首次公开募股招股说明书中披露的盈利预测的偏差和准确性。本文的第二个目的是确定作为衡量盈利准确性的绝对预测误差与公司的一些特定特征之间的关系,如公司的规模、杠杆率、预测期、管理层所有权、向投资者发行的股份数量(相对于IPO前的总股份)。方法:对2006-2015年在华沙证券交易所主要市场进行IPO并在IPO招股说明书中披露盈利预测的102家国内公司进行实证分析。预测误差(FER)和绝对预测误差(AFER)被用作衡量盈利预测准确性的指标。采用非参数检验来实现所采用的目标。调查结果和附加值:结果显示,平均而言,预测收益超过实际收益(即收益预测是乐观的),预测不准确。此外,乐观的预测比悲观的预测更不准确。多元回归模型的结果表明,三个自变量可能影响绝对预测误差的水平:公司规模、管理层持股和预测期。

Research background: Managerial scientists use a lot of modelling techniques for business processes. In this paper we are focused on agent-based modelling and simulations, which emerged in the last two decades as a new approach. Autonomous and interacting intelligent agents are able to model and simulate complex systems in the business sphere. With the use of agent-based modelling and simulations we are able to understand how macro level outcomes are affected by micro level processes and vice versa. Purpose of the article: The purpose of the paper is to introduce recent development in the area of agent-based modelling and simulations focused on the business domain. Managers often have to make difficult decisions under the uncertainty and high risks. Agent-based modelling can provide powerful tools for lowering those risks through a possibility of running experiments, which is normally impossible in economics. In the second part we want to support the usefulness of agent-based simulations with our own simulations. Methods: The method used in this article is an agent-based simulation in a multi-agent system. We use a framework called MAREA. It is a simulation environment with integrated ERP system based on REA ontology. Our simulation model is based on a retail company that sells electronics. For simplicity, in our setup we trade with computer cables. Findings & Value added: In our simulations we experimented with the quality of sales service provided by company’s sales representatives. We investigated the impact of quality of sales service on company KPIs under the changing environment circumstances represented by disturbance agent. The quality of sales service is a part of quality of service and thus it affects the perception of brand and loyalty of customers towards the company. In our simulation setup we work with two types of customers, long-term customers and new ones. The result is that quality of sales service has mostly positive effects on company KPIs.
研究背景:管理科学家对业务流程使用了大量建模技术。在本文中,我们专注于基于代理的建模和模拟,这是在过去二十年中出现的一种新方法。自主和交互智能代理能够对商业领域的复杂系统进行建模和模拟。通过使用基于主体的建模和模拟,我们能够了解宏观层面的结果如何受到微观层面过程的影响,反之亦然。本文的目的:本文的目的是介绍以商业领域为重点的基于代理的建模和模拟领域的最新发展。管理者往往不得不在不确定性和高风险的情况下做出艰难的决策。基于代理的建模可以提供强大的工具,通过运行实验的可能性来降低这些风险,这在经济学中通常是不可能的。在第二部分中,我们希望通过自己的模拟来支持基于代理的模拟的有用性。方法:本文使用的方法是在多智能体系统中进行基于智能体的模拟。我们使用一个名为MAREA的框架。它是一个基于REA本体的集成ERP系统的仿真环境。我们的模拟模型基于一家销售电子产品的零售公司。为了简单起见,在我们的设置中,我们使用计算机电缆进行交易。调查结果和附加值:在我们的模拟中,我们对公司销售代表提供的销售服务质量进行了实验。我们调查了在以干扰因子为代表的不断变化的环境条件下,销售服务质量对公司KPI的影响。销售服务质量是服务质量的一部分,因此它影响着客户对品牌的感知和对公司的忠诚度。在我们的模拟设置中,我们与两种类型的客户合作,长期客户和新客户。结果表明,销售服务质量对公司KPI的影响主要是正向的。

Determinants of payout policy and investment attractiveness of companies listed on the Warsaw Stock Exchange 华沙证券交易所上市公司派息政策和投资吸引力的决定因素
IF 5.7 Q1 Economics, Econometrics and Finance Pub Date : 2017-05-01 DOI: 10.24136/EQ.V12I4.35

Making decisions concerning the payout policy depends on many diversified neoclassical and behavioral determinants. Although these factors are well-described in the literature, there is still a research gap concerning the lack of a comprehensive impact model of payout policy determinants on the investment attractiveness of shares. The aim of this paper is to present the diverse nature of relationships between different forms of cash transfer to the shareholders and investments attractiveness of public companies in the context of determinants of payout policy. The possibility to achieve this objective was conditioned by empirical verification of research hypothesis stating that the diversify of payout forms is accompanied by the different determinants of payout policy which condition an effective investment of stock investors capital. The empirical research was conducted on the electromechanical companies which were listed on the Warsaw Stock Exchange in years 2006-2015. The data for analysis were mainly collected from database Notoria Service SA and Stock Exchange Yearbooks. The calculations were carried out using the methodology of taxonomic measure of investment attractiveness, as well as dividend premium and share repurchase premium. The final conclusion of our research is that the companies conducting the payout policy in different forms of cash transfer differ in terms of many characteristics, such as: financial standing, market value, ownership structure, company’s size and age.

有关支付政策的决策取决于许多不同的新古典主义和行为决定因素。虽然这些因素在文献中有很好的描述,但仍然存在一个研究缺口,即缺乏一个全面的股息政策决定因素对股票投资吸引力的影响模型。本文的目的是在支付政策决定因素的背景下,呈现不同形式的现金转移给股东和上市公司投资吸引力之间关系的多样性。实现这一目标的可能性取决于对研究假设的实证验证,即支付形式的多样化伴随着支付政策的不同决定因素,这些决定因素决定了股票投资者资本的有效投资。实证研究对象是2006-2015年在华沙证券交易所上市的机电公司。分析数据主要来源于数据库Notoria Service SA和Stock Exchange yearbook。计算采用投资吸引力分类学度量方法,以及股息溢价和股票回购溢价。我们研究的最终结论是,实施不同形式现金转移支付政策的公司在财务状况、市场价值、股权结构、公司规模和年龄等诸多特征上存在差异。此外,它们的投资吸引力因支付的规律性、证券交易情况和股东偏好而异。本文的附加价值是一种评价资本投资的新方法,特别强调支付政策的决定因素。

Although these factors are well-described in the literature, there is still a research gap concerning the lack of a comprehensive impact model of payout policy determinants on the investment attractiveness of shares. The aim of this paper is to present the diverse nature of relationships between different forms of cash transfer to the shareholders and investments attractiveness of public companies in the context of determinants of payout policy. The possibility to achieve this objective was conditioned by empirical verification of research hypothesis stating that the diversify of payout forms is accompanied by the different determinants of payout policy which condition an effective investment of stock investors capital. The empirical research was conducted on the electromechanical companies which were listed on the Warsaw Stock Exchange in years 2006-2015. The data for analysis were mainly collected from database Notoria Service SA and Stock Exchange Yearbooks. The calculations were carried out using the methodology of taxonomic measure of investment attractiveness, as well as dividend premium and share repurchase premium. The final conclusion of our research is that the companies conducting the payout policy in different forms of cash transfer differ in terms of many characteristics, such as: financial standing, market value, ownership structure, company’s size and age.

MACROECONOMIC ASPECTS OF BANKS’ CREDIT RATINGS 银行信用评级的宏观经济方面
IF 5.7 Q1 Economics, Econometrics and Finance Pub Date : 2017-03-31 DOI: 10.24136/EQ.V12I1.6
Patrycja Chodnicka-Jaworska
Research background: The practical analysis suggests that credit ratings are especially significant for banks. The literature review suggests that in previous analysis researchers usually took into consideration financial factors of the banks’ credit ratings methodology. This article analyses the impact of macroeconomic factors on the banks’ credit ratings. Purpose of the article: The paper examines and analyses the impact of the macroeconomic risk factors on the credit ratings received by banks. In the article, the methodology of credit risk assessment proposed by Moody’s Investor Service and Standard & Poor’s Financial Service is presented. Two hypotheses are put herein. The first one is: Changes in countries’ credit ratings convey new information and influence on banks’ financial condition. The second hypothesis is: A highly-developed, stable economy with an advanced financial market has a positive influence on banks’ credit rating assessment. Methods: The study used banks’ and countries’ ratings assigned by Standard & Poor's and Moody's for the period from 1 January 2005 to 1 January 2016. To verify the hypotheses static panel data models have been applied. Findings & Value added: In credit rating agencies guidelines and previous research, the impact of countries’ credit ratings on those received by banks is not indicated. The impact of macroeconomic factors has not been verified. The analysis confirms that changes in countries’ credit ratings convey new information and influence the banks’ environment condition. But only for the assessment given by S&P the condition of banking sector is an important group of factors. For all verified types of credit ratings the risk of country is presented by countries’ credit rating, not by particular factors. These analyses suggest that during the risk estimation process prepared by banks, a country’s risk represented by its credit ratings should be taken into consideration more often than particular macroeconomic factors.
研究背景:实践分析表明,信用评级对银行尤为重要。文献综述表明,在以往的分析中,研究人员通常考虑银行信用评级方法的财务因素。本文分析了宏观经济因素对银行信用评级的影响。文章的目的:本文考察和分析了宏观经济风险因素对银行信用评级的影响。本文介绍了穆迪投资者服务公司和标准普尔金融服务公司提出的信用风险评估方法。这里提出了两个假设。第一,国家信用评级的变化传递了新的信息,对银行的财务状况产生了影响。第二个假设是:高度发达、稳定的经济和发达的金融市场对银行的信用评级评估有积极的影响。方法:研究使用了标准普尔和穆迪在2005年1月1日至2016年1月1日期间对银行和国家的评级。为了验证这些假设,我们采用了静态面板数据模型。发现与增值:在信用评级机构指南和以往的研究中,没有指出国家信用评级对银行收到的信用评级的影响。宏观经济因素的影响尚未得到证实。分析证实,国家信用评级的变化传达了新的信息,并影响了银行的环境状况。但只有在标准普尔给出的评估中,银行业状况才是一组重要因素。对于所有经过验证的信用评级类型,国家的风险都是由国家的信用评级来呈现的,而不是由特定因素来呈现的。这些分析表明,在银行编制的风险评估过程中,应更多地考虑一国信用评级所代表的风险,而不是特定的宏观经济因素。

INTERVENTION ON THE AGRICULTURAL LAND MARKET IN RELATION TO THE END OF THE TRANSITIONAL PERIOD FOR PURCHASING AGRICULTURAL LAND BY FOREIGNERS 外商购买农地过渡期结束后对农地市场的干预
IF 5.7 Q1 Economics, Econometrics and Finance Pub Date : 2017-03-31 DOI: 10.24136/eq.v12i1.9

Research background: A traditional form of state intervention in agriculture comprised regulating the rights to ownership. One of the often discussed aspects of regulations refers to those binding for foreigners. Purpose of the article: The objective of the article was to analyse the position (of the Euro-pean Economic and Social Committee and the Polish legislator) regarding the phenomenon of purchasing agricultural property by foreigners as well as the opinions of farmers on the consequences for the agricultural land market resulting from ending the transitional period in Poland for purchasing agricultural property by foreigners as on 1 May 2016. Methods: Direct studies were conducted in 2015 among 86 farmers in the Warmian-Masurian Voivodeship. Findings & Value added: The main reason for such a discussion conducted glob-ally and in Europe is the phenomenon of excessive concentration and the use of land for non-agricultural purposes. Whereas, the European Economic and Social Committee indicates that in order to limit unfavourable practices in the EU member states, activities directed at preventing speculation, preserving local traditions and ensuring a proper usufruct of land should be permitted. The majority of farmers were afraid of the changes in the agricultural land market after the end of the transitional period in purchasing agricultural property by foreigners. They emphasised the above by expressing opinions on regulations binding in the transitional period and their effectiveness. With regard to the provisions of the Act of 5 August 2015, farmers were afraid of an increase in prices of agricultural land and the capital advantage of foreigners.
研究背景:国家干预农业的传统形式包括对所有权的调节。法规中经常讨论的一个方面是对外国人的约束力。文章的目的:文章的目的是分析(欧洲经济和社会委员会和波兰立法者)对外国人购买农业财产现象的立场,以及农民对2016年5月1日结束波兰外国人购买农业财产过渡期对农业土地市场造成的后果的意见。方法:2015年对温姆-马苏里省86名农民进行直接调查。调查结果&增值:在全球和欧洲进行这种讨论的主要原因是过度集中和土地用于非农业用途的现象。鉴于欧洲经济和社会委员会指出,为了限制欧盟成员国的不利做法,应允许旨在防止投机、保护当地传统和确保适当的土地使用权的活动。大多数农民担心外国人购买农用财产过渡期结束后农用土地市场的变化。他们就过渡期具有约束力的规定及其效力发表了意见,强调了上述问题。关于2015年8月5日法案的规定,农民担心农业用地价格上涨和外国人的资本优势。

INTERREGIONAL R&D SPILLOVERS AND REGIONAL CONVERGENCE: A SPATIAL ECONOMETRIC EVIDENCE FROM THE EU REGIONS 区域间研发溢出与区域趋同&来自欧盟区域的空间计量证据
IF 5.7 Q1 Economics, Econometrics and Finance Pub Date : 2017-03-31 DOI: 10.24136/EQ.V12I1.1
Andrea Furková, M. Chocholatá
Research background: Many contemporary empirical studies and also most of economic growth theories recognize the importance of innovation and knowledge for achieving an economic growth. A large part of empirical literature has treated the issue of beta convergence without the spatial aspect, i.e. the possible spatial dependence among regions or states in growth process was neglected. Purpose of the article: In this paper, we investigate the link between selected R&D (Research and Development) indicators as proxies for the regional innovation and knowledge and economic performance of the region. We also assume a significant role of regional R&D spillovers in the regional growth process determination. Methods: The main methodological basis for our analysis is beta convergence approach and the dataset under the consideration consists of 245 NUTS 2 (Nomenclature of Units for Territorial Statistics) EU (European Union) regions during the 2003–2014 period. Our anal-ysis is made with respect to spatial interactions across the EU regions. Findings & Value added: The influence of R&D indicators on the economic growth has been confirmed, and spatial interconnection across the EU regions have been proven. Potential existence of geographical R&D spillovers across the EU regions was examined by for-mulation of additional beta convergence model with spatial lag variables. We have identified that the influence of R&D spillovers is not strictly restricted to the neighbouring regions, but they spread across a larger area. For the construction of spatial lags of R&D indicators different spatial weight matrices were considered.
研究背景:当代许多实证研究以及大多数经济增长理论都认识到创新和知识对实现经济增长的重要性。大部分实证文献在没有空间方面的情况下处理了贝塔收敛问题,即忽略了增长过程中区域或状态之间可能的空间依赖性。本文的目的:在本文中,我们调查了作为区域创新指标的选定研发指标与该地区知识和经济绩效之间的联系。我们还假设区域研发溢出效应在区域增长过程决定中发挥着重要作用。方法:我们分析的主要方法论基础是贝塔收敛法,所考虑的数据集由2003-2014年期间的245个NUTS 2(领土统计单位命名法)欧盟(欧盟)地区组成。我们对欧盟各地区的空间互动进行了分析。研究结果与附加值:研发指标对经济增长的影响已得到证实,欧盟各地区的空间互联互通也已得到证实。通过模拟具有空间滞后变量的附加贝塔收敛模型,考察了欧盟各地区地理研发溢出的潜在存在。我们已经发现,研发溢出效应的影响并不严格局限于邻近地区,而是蔓延到更大的地区。对于研发指标空间滞后的构建,考虑了不同的空间权重矩阵。

Rafal Zelazny, J. Pietrucha
Research background: A literature review on innovativeness and institutions pointing to their correlation and the possibility of their joint examination. Purpose of the article: This paper attempts to devise a measurement method for a creative economy, where as a result of feedback between institutions, human capital and technology conditions facilitating the development of creativity are created. Methods: An empirical meta-analysis of indicators characterising innovativeness and insti-tutional environment was carried out, following the hypothesis that at least in part they contain common information on creative economy. Findings & Value added: The new synthetic index, a creative economy index (CEI), was constructed. The study was conducted for a group of 34 economies of the European Union and its associated states for the period of 2005–2014.
