The constriction of global resources and the sustained growth of population bring resources pressure to society. At the same time, the problem of environmental pollution and ecological imbalance cannot be ignored. In 2008, the United Nations Environment Programme launched the “Green Economy” initiative to integrate the concept of green and sustainable development into economic development. In this context, resource conservation, environmental protection and sustainable development are the best choices in this era. The construction industry is the pillar industry of Chinese economy. It is important for the construction industry to implement sustainable development. Faced with the pressure of resources and higher environmental requirements, green supply chain is an important means to enhance the environmental friendliness of construction industry and realize the rapid development of enterprises (Beamon, 1999; Ansari & Kant, 2017).

Nowadays when businesses are facing intense rivalries, it is worthwhile for business organizations to recruit and retain workforce by adopting successful strategies to gain or sustain competitive advantage. Literature indicates that many factors (e.g., economic, financial, legal, structural, technical, procedural, and social) play an important role in determining organizational success (Pourhanifeh & Mazdeh, 2016). Moreover, literature also highlights the importance of workforce which is considered as an essential element for organizations to outperform. Riaz et al. (2018) mentioned that currently organizations are putting more efforts to explore employees’ innovative behaviour in order to obtain and sustain edge over competitors. Farid et al. (2017) highlighted that majority of the studies investigating innovative behaviour of employees were conducted at organizational level. They realized the need to conduct studies exploring innovativeness of employees at individual level.

In the contemporary economic reality, which is based on relations, the role of trust both in the intra- and inter-organisational context is growing in importance. Impersonal trust is characterized by considerable durability and forms a solid framework for developing interpersonal trust. In consequence, many researchers’ attention is drawn towards practices aimed at the development of such trust. The goal of the paper is to analyse potential relations between the degree of impersonal trust and innovative culture and, in particular, to operationalise the variables, i.e. determine the dimensions of impersonal trust and innovative culture, estimate the impact of the individual dimensions of the former onto those of the latter. The survey was conducted in Poland among 630 employees of large and mediumsized enterprises. Verification of the theoretical model was performed based on structural equation modeling. The research led to the identification of dependencies between the particular dimensions of impersonal trust and innovative culture, confirming the importance of impersonal trust in the process of shaping organisational culture. Impersonal trust was recognized as a separate construct which determines the nature of innovative culture. Feeling of security has special significance at workplace because guarantees stability, durability and openness in relations, enhances creativity of staff and gives them freedom to try non-conventional solutions to problems. Organisational assurance, i.e. a conviction about the clarity of rules and principles, open communication and making staff feel they are included in organisational processes, has a weaker impact on the dimensions of innovative culture when compared to feeling of security.

In their response to the necessity to meet the demands of customers, the enterprises are forced to reduce the time of order delivery. Today, almost every enterprise has its own warehouse facilities or outsources warehouse processes. Therefore, the contemporary warehouses play a significant role in production and service networks. The maintenance of high efficiency of warehouse processes determines the competitive functioning of enterprises. Continuous progress in this area sets the pace for these changes. Nevertheless, despite of the desire to reduce costs while increasing the efficiency of the warehouse process, you cannot forget about employees. In addition to efficiency and the level of generated costs, a warehouse employee is one of the factors that not only affects the shape of the logistics system in an enterprise, but also affects all links in the supply chain. This study is intended to research the impact of technological and organizational innovation implemented in the warehousing process on the efficiency of picking processes and staff workload on picking stations. The research was performed with warehouse simulation models developed in FlexSlim 3D Simulation Software. The simulated warehouses represent the warehouses in B2C (Business to Customer) logistics. They are about the layout of bag-type warehouse and the size and shape of the assortment varies. The size of storage zone is the same for all three warehouses. In these warehouses the assortment is arranged randomly. For each model, several simulations have been performed. The conducted research has shown that the results of technological and organizational innovation implemented in the warehousing process should be in general evaluated positively. Both the warehouse productivity and the picking process efficiency increased. The staff workload decreased, which is reflected in greater work comfort for a man and which supports implementation of control activities. However, it should be noted that implementation of the technological and organizational innovation in the warehousing processes adopted in various enterprises changes the labor market, thus it is possible that some problems with maintaining current employment levels will occur.

The paper studies a new point of view and the approach to profit as an inherent part of business finance as well as a symbol of every healthy economy. The fundamental function of the profit is a stimulus; it means initial motivator of the business activity. The profit provides core resources for survival at the business start and after the stabilization, it is the synonym for progress. The aim of this paper is to detect significant change-points in times series of EBITDA during the analysed period in every country of the Visegrad Group to recognize the progress years in the monotonic development. We use a method of homogeneity test of time series that delivers significant robust results. We observe the variable EBITDA to eliminate different tax, interest and depreciation policies of these emerging countries. The original research of this article is based on empirical results of business profits of the sample of 3,853 enterprises covered by the broad theoretical review. Firstly, we identify missing values; and detect the outliers by Z-score and Grubbs test. EBITDA of 1,058 Slovak enterprises, 688 Czech enterprises, 1,376 Polish enterprises and 731 Hungarian enterprises is analysed during the period from 2010 to 2018. We eliminate the inconsistent observations and construct average values of EBITDA. Secondly, we prove normality by Jarque-Bera test, and support it by Shapiro-Wilk test, Anderson-Darling test, Lilliefors test to deliver reliable results. Thirdly, we find an independency of distribution that confirm randomness by the Box-Pierce test. And finally, we identify the years that affect heterogeneity of EBITDA in the countries of the Visegrad Four. We uncover some really surprising results. For all countries in the Visegrad Four, the year 2013 is detected as a change-point at a significance level of 0.05. This significant year shifts EBITDA between two homogeneous series with corresponding central lines and recognizes the similar annual development within the groups. In addition, we discuss the results to the areas and factors affecting the business risk. The adjustable area represented by the business dynamism has no significant impact on the development of EBITDA. The uncontrollable macroeconomic factors such as a GDP, unemployment rate, inflation rate, average monthly gross wage, and Ease of doing business index demonstrate the same development of Slovak, Czech, Polish and Hungarian enterprises. We connect our gained results to the undisputed influence of these factors and its derived components on monotonic development of EBITDA. Despite the fact, that the countries are not economically interconnected as they used to be in the past, in has to be underlined that their mutual relations are still very narrow and close and that might be the reason, why identical results are achieved in the countries with divergent development.
