Innovation in small family firms: A qualitative multipla case study
Authors: Urban Jan , Caha Zdeněk
Published: January 2021

Family firms, accounting globally for the majority of companies, are the backbone of many national and local economies. Despite their importance as both employers and producers/service providers, research on these firms, analyzing their innovative behavior or comparing it with other forms of companies, has often been describing them as more conservative and less risk-raking, generating thus less innovation compared with other types of businesses. The goal of this study was to analyze the scope innovative activities in family owned companies on the basis of an empirical qualitative survey, founded on descriptive multiple-case study analysis of fifteen small, locally operating family owned firms in retail and service-industry, which have successfully survived 5 or more years in business. It used semi structured interviews with family owners and focused on identifying their attitudes to innovation as well as their skills to apply innovations of various types, important for their market competitiveness. The results of the survey, contrary to some earlier findings pointing to family firms ́ conservativeness, showed that these firms, due to their specific organizational culture, rely on innovations substantially, though the main focus of their innovations tends to be on product/technological changes as well as innovations in clients ́ relations.

The question of business performance assessment has been discussed by many researchers. Some resulting indicators of business performance can be applied in all enterprises (e.g. ROE, ROA), some have limited use (e.g. Tobin ́s Q). This paper focuses on finding the aspects (indicators), that could affect business performance itself, rather than to propose new indicators of business performance. The results of this analysis could help the management of enterprise to focus on the right objectives in the future. The research adopted quantitative approach. It is based on analysis of fourteen indicators (i.e. their values) processed in order to prove or disprove their statistical interrelationship with chosen performance indicators (ROE, ROS). The dataset, describing 784 large enterprises in the Czech Republic, was downloaded from Albertina – Gold edition. Data were statistically tested using Spearman ́s correlation coefficient. Findings of this research indicate that in the case of few indicators (such as Equity or Total debt in the case of ROS) the relationship can be proven. These indicators are presented, and results are discussed in the paper, together with the possible future research.

O objetivo deste artigo consiste em apresentar estudos realizados no território da Comunidade Autônoma de La Mancha (Espanha), em nível de estágio pós-doutoral, com o intuito de investigar a implementação de estratégias de desenvolvimento pautadas no conceito de patrimônio agrário, e, subsequentemente, prospectar bens agrários eventualmente presentes na microrregião de Canoinhas (Brasil), capazes de proporcionar processos de patrimonialização, com vistas à elaboração de estratégias congêneres de desenvolvimento territorial. A abordagem metodológica considerou o exame dos planos de desenvolvimento da Comunidade Autônoma de Castilla-La Mancha, fundamentou-se em trabalhos de campo realizados em várias províncias daquele território espanhol e amparou-se na revisão de literatura disponível sobre a categoria conceitual de patrimônio agrário. Dentre os principais resultados, destacam-se: obtenção de dados e informações acerca dos bens agrários presentes no território espanhol, em especial, a atividade vinícola e a Rota de Dom Quixote, que vem recebendo importantes esforços de patrimonialização; identificação de um conjunto de bens patrimoniais agrários existentes na microrregião de Canoinhas, materiais e imateriais, que admitem patrimonialização, em especial, a produção da erva mate e o pixirum. Conclui-se que a busca por referenciais ao processo de patrimonialização pode se pautar em estratégias análogas desenvolvidas anteriormente em outros territórios, caso da Comunidade Autônoma de Castilla-La Mancha, na Espanha, e que a viabilização desta estratégia dependerá de um processo constituído por várias etapas, que necessariamente exigirá a mobilização dos atores sociais e políticos da microrregião de Canoinhas.

. Концепция Си Цзиньпина "сообщества единой судьбы человечества" (СЕСЧ) является одной из главных философско-дипломатических стратегий КНР в новой эпохе. Цель статьи – показать, каким образом "сообщество единой судьбы человечества" связано с древнекитайскими концепциями политической культуры и марксистской философией. Использованы исторический и структурный методы политологии. Новизна ис- следования состоит в том, что СЕСЧ творчески развивает теорию марксизма, которая отражает взгляд на мир и человечество с точки зрения стран и народов, их культуры и религии. Проанализирована взаимосвязь марксистской теории с политической культурой Китая, основанной на традициях, китайских историко-культурных ценностях. Историко-культурное наследие Поднебесной обогащает и современную политическую культуру Китая, роднит её с марксизмом. Xi Jinping’s concept a community with a shared future for mankind is one of the significant Chinese philosophical and diplomatic strategies in the new era. The purpose of the article is to show how a community with a shared future for mankind is bound with the ancient Chinese concepts of political culture and Marxist philosophy. The authors use the historical and structural methods of political science. The novelty of the study is that the concept creatively develops Marxism, which reflects a view of the world and humanity from the point of view of countries and peoples, their culture and religion. There has been analyzed the relationship of Marxist theory with the political culture of China, based on Chinese traditions, historical and cultural values. The Chinese concept of a community with a shared future for mankind, enriched by Marxist principles, shows the interconnectedness and interdependence in the effective development of large and small countries, opens up the ways of resolving conflicts peacefully for the peoples and governments of various states, leads humanity to a universal prosperity. Chinese historical and cultural heritage enriches the modern Chinese political culture and makes it similar to Marxism.
Перспективы развития трансграничных отношений Дальнего Востока России в контексте выдвинутых ведущими странами СВА стратегий международного сотрудничества
Authors: Севастьянов С. В.
Published: January 2021

В статье исследуются возможности и ограничения, возникающие при попытках сопряжения выдвинутых в последние годы ведущими странами Северо-Восточной Азии (Китаем, Японией и РК) стратегий международного сотрудничества со стратегическими инициативами и планами российского руководства по ускоренному развитию Российского Дальнего Востока (РДВ). В этих целях проанализировано участие иностранных партнеров в бизнес-проектах на РДВ, в том числе с опорой на создаваемый комплекс преференциальных режимов для инвесторов, в первую очередь, таких, как территории опережающего развития (ТОР) и Свободный порт Владивосток (СВП). Особое внимание при этом уделено анализу влияния геополитической останов- ки в мире и регионе на принятие странами СВА решений по участию или неучастию в предлагаемых Россией проектах международного сотрудничества на РДВ. Методиче- ской основой работы стало изучение выступлений лидеров стран СВА, в том числе на Восточном экономическом форуме, статических материалов и научных исследований по данной тематике, и их анализ с опорой на актуальные для региона СВА теории международных отношений. The article examines the possibilities and limitations that arise when trying to match the strategies of international cooperation put forward in recent years by the leading countries of Northeast Asia (China, Japan and the Republic of Korea) with the strategic initiatives and plans of the Russian leadership for the accelerated development of the Russian Far East (RFE). To this end, the participation of foreign partners in business projects on the Russian Far East was analyzed, including with reliance on the created complex of preferential regimes for investors, first of all, such as priority development territories (PDT) and the Free Port of Vladivostok (FPV). Special attention is paid to the analysis of the influence of the geopolitical situation in the world and the region on the adoption by the NEA countries of decisions on participation or non-participation in the projects of international cooperation proposed by Russia on the RFE. The methodological basis of the work was the study of the speeches of the leaders of the NEA countries, including at the Eastern Economic Forum, statistical materials and scientific research on this topic, and their analysis based on the theories of international relations that are relevant for the NEA region.
