The Effects of Organizational Structure on the Entrepreneurial Orientation of the Employees

This study aims to investigate the effects of organizational structure on the entrepreneurial orientation of the employees in metal industries of Kaveh Industrial City of Iran. The research was conducted in 2012. The methodology of this research is functional according to its objective, and it is a descriptive survey according to its data collection method, and it is a quantitative research due to the type of its data that have been collected by questionnaire. In order to assess the dimensions of the organizational structure we have used Robin's Standard Questionnaire and in order to measure the entrepreneurial orientations, we have used Dess and Lumpkin's standard questionnaire of entrepreneurial orientation. The pollution of the research was included 4700 employee involved in metal industries of Kavek Industrial City, among whom, 355 people was selected as the research sample by using Cochran formula and sampling method of relational stratified random sampling method. Then we applied Spearman's regression test and multi-regression (in SPSS) and the Structural Equation Modeling (in LISREL) to analyze the data. The analysis showed that the organizational structure has a positive significant effect on the entrepreneurial orientation of the employees of the organization. The finding of this research can help the managers of the metal industry identify the weaknesses and strengths of their organizational structure and the appearance of people's orientations and behaviors toward the entrepreneurial activities. 1.

INTRODUCTION
In recent years, the increasing competition and the instability of the environmental conditions has led to new situations in which the big organizations that have not changed their methods and structures fail to compete the small organizations that are more fl exible and more innovative.e organizations that encourage the entrepreneurship and nurture the talents of the people are very valuable for the society.Nowadays, the organizations are increasingly placed in situations in which it is necessary to tend toward the entrepreneurial activities (Shepherd, et al., 2008).e organizations have to meet the conditions in which the spirit of entrepreneurship governs the whole organization, and the employees can approach the entrepreneurial activities whether individually or in group.is is why diff erent organizations willingly promote the entrepreneurial activities among their employees.One of the most important factors that facilitate the entrepreneurship in organizations is the suitable organizational structure that is appropriate to the goals of that organization.Any organization that intends to do entrepreneurial activities must adopt a fl exible and entrepreneurial structure.e suitable conditions for the entrepreneurial activities cannot be created without the needed backings, but the organizational structure has to make the grounds for appearance of such backings (Johnson and Van de Ven, 2002).us the identifi cation of such factors plays an important role in creating such an entrepreneurial space and reinforces the fl ows of creativity and innovation in organization.
e main problem of this research deals with the eff ects of the diff erent dimensions of organizational structure on the entrepreneurial orientations of the employees in organization, and to specify the relationship between these dimensions to understand the ways of conducting people's orientations and tendencies toward the entrepreneurial activities and to improve the organizational entrepreneurship.

Organizational structure
e studies on the successful organizations show that one of the most eff ective factors on the establishment of diff erent dimensions of entrepreneurial orientation in organizations is the organizational structures of those organizations.Mintzberg (1972) defi nes the organizational structure as follows: organizational structure can be defi ned as a set of methods that separate the tasks of the individuals in diff erent sections and then coordinate those tasks (Willem and Buelens, 2009).Organizations have diff erent types of structures that are used based on the needs and conditions of each organization.In a general classifi cation, there are two types of structures: mechanical and organic.Mechanical structure is used for stable and predictable environments and organic structures are used for turbulent and instable environments (Gresov and Drazin, 2007).Mechanical structure of the organization is known by some characteristics like the complexity, centralization, formalization, and planned behaviors in form of the rules and regulations (Mihm et al., 2010).On the other hand, organic organizational structure is fl exible and is known by some characteristics like decentralized authorities, less rules and regulations, and less formal communications (March and Simon, 2009).
Based on the available defi nitions in the literature about the structural dimensions of the organization, it is too hard to specify a set of dimensions for the structural organization without having a specifi c framework and specifi c goals (Morton and Hu, 2008).Accordingly, referring to the proposed hypotheses of this research, Robbins's research (1998) on the dimensions of the structure (including three dimensions of complexity, formalization and centralization) has been selected as our criteria for studying the organizational structure due to its scientifi c backings.
Complexity: According to Daft, complexity is the number of the management levels that exist in the organization (Daft, 2006).Generally, complexity refers to the number of job titles (inter-organizational job distribution), number of the hierarchy and management levels, educational levels, and geographical distribution of the departments and branches of the organization.complexity is divided to two classes: vertical complexity and geographical complexity (Gresov and Drazin, 2007); Formalization: formalization refers to the scale of using rules and regulations for describing the behaviors (Liao, et al, 2010).Generally, formalization is the scale of defi ning the rules, regulations, instructions, provisions, job descriptions that are part of the organization (Gresov and Drazin, 2007); Centralization: e third dimension of the organizational structure is the centralization.Most researchers agree that the centralization refers to the concentration of the power of decision making at the top levels of the management in organization (Wilm and Bones, 2009;Liao, et al, 2010;Child, 2008).More centralization can integrate the policies of the organization and reduces the risks of the employees at the lower levels of the organization who have less information or skills (Katsikea et al, 2011).

Entrepreneurial orientation
In today's dynamic competitive environments and global rapid changes, the organizations are increasingly committed to do entrepreneurial activities in order to survive and gain competitive successes (Covin and Kuratko, 2008).Nowadays, entrepreneurship is considered as an important tool for the development because the entrepreneurial persons can create the grounds of the successfulness.Naman and Slowin (1993) believe that in turbulent and instable environments the companies are more willing to be innovative, risktaker, and pioneer.An entrepreneurial organization is always able to adjust itself with the changes occurring in its external environment and makes its programs compatible with the environmental changes.e idea of organization entrepreneurship is a subject in the global economy the managers must not only be familiar with it, but they have to understand and implement it in their organization.In order to be successful, the organizations have to have a vision that promotes and encourages the innovation and risk-taking so that they can be adapted to the ever-changing global economy.Organizational entrepreneurship refers to the innovated products or processes that are emerged through creating the entrepreneurial culture in a pre-established organization (Hornsbey et al., 1993).e organizations that wish to conduct the organizational entrepreneurship successfully will need an entrepreneurial orientation.Entrepreneurial orientation refers back to the activities of determining the strategies that the businesses use to identify and conduct new-emerging companies.Entrepreneurial orientation off ers a mental framework and a perspective on the entrepreneurship that is mirrored in the current process of the company and the organizational culture of that company.Most researchers believe that if the organizations have a strong entrepreneurial orientation they would meet their goals more effi ciently (Dass and Lumpkin, 2005;Chen, et al, 2006;Naldi, et al, 2007).In other words, entrepreneurial orientation includes the intentions and activities of the key actors in the process of dynamic productions in light of the new-emerged opportunities.Covin and Slowin (1989) suggest that the entrepreneurial orientation is a multi-dimensional construct and it can be evaluated from diff erent points of view (Chang, et al. 2007).For example, Miller (1983) suggests specifi c dimensions for describing entrepreneurial orientation.He introduces entrepreneurial company as a company dealing with the markets with innovative products, having low risks, being pioneer in market, and pressuring the competitors.Innovation is the scale of the willingness of the companies to approach the new ideas and creative processes whose results may be emerged in new products, services, and/or technological processes.Innovation requires separating the company from its current technologies and moving beyond its current situation (Chadwick, et al, 2008).Risk-taking implies the willingness of the companies to assign its main resources to the projects that may or a) b) c) may not being successful and thus it is possible for these projects to fail.Moreover, risk-taking refers to the rapid following-up of the opportunities, rapid supply of the resources, and courageous activities (Chang, et al, 2007).Pioneer organizations supervise the market procedures, detect the future needs of the customers, and predict changes in demands or any problems that can lead to new opportunities for the company.Lumpkin and Dess (1996) added to further factors that can play important role in the entrepreneurial orientation: aggressive approach and autonomy.Aggressive approach refers to the willingness of the company to be involved in direct and hard challenge with the competitors in order to improve the situation of its own market.e companies that try to build their competitive position aggressively and use the opportunities forcefully to benefi t can preserve their competitive advantage in long term if their goal is to succeed the competitors and not to damage them (Dess and Lumpkin, 2005).Autonomy refers to the independent activities of the individuals or groups in order to come to new ideas and their implementation.In other words, organizational actors follow self-controlling opportunities, independent activities, making key decisions and implementing new ideas independently (Chang, et al, 2007).Generally, the characteristics of entrepreneurial orientation can be generalized to the styles of decision-making and the activities of the members of an organization.ese factors (including innovation, risk-taking, pioneering, aggressive approach and autonomy) usually work together to improve the entrepreneurial performance of the organization.
e literature review shows that the organizational structure has an aff ects the entrepreneurial orientation of the employees.Among the most important studies in the mentioned literature we can refer to the followings: Yao, et al. (2009) have introduced organizational factors such as the organizational structure, organizational strategy, and organizational culture as the important and eff ective factors on the performance.Moreover, Lumpkin, et al, (2010) believe that autonomy is the most important factor among the dimensions of the entrepreneurial orientation.ey found that the autonomy is the most eff ective factor on the performance of the organization.Besides, Katsikea, et al, (2011) point to the positive eff ects of the formalization and centralization on the occupational feedbacks of the employees and add that the centralization has a negative relationship with job independence and job diversity.
Focusing on the both mentioned main constructs, the hypotheses of this research are proposed as follow: Main hypothesis (Ha): the structure of an organization is eff ective on the appearance of the entrepreneurial orientations of the employees of metal industries.Subsidiary hypothesis 1 (Hb1): the scale of the complexity of organization is eff ective on the entrepreneurial orientation of the employees of metal industries.Subsidiary hypothesis 2 (Hb2): the scale of the formalization of organization is eff ective on the entrepreneurial orientation of the employees of metal industries.Subsidiary hypothesis 3 (Hb3): the scale of the centralization of the decision-makings in organization is eff ective on the entrepreneurial orientation of the employees of metal industries.

THEORETICAL FRAMEWORK OF THE RESEARCH
Considering the main objective of this research that is to study the role f organizational structure on the entrepreneurial orientation of the employees of metal industries, and considering the hypotheses of the research, the theoretical framework of the research is presented in fi gure 1.

METHODOLOGY OF THE RESEARCH
Since in this research a causal relationship is supposed to be studied, the methodology of the research is causal according to the relationship between the variables, while we have used structural equation model to come to a inclusive study of the conceptual model of the research.Structural equation model is the best tool for the researches in which the observed variables have measuring errors, and the relationship between their variables is complex.Using this method we can study the indexes or observed variables on one hand and to assess the causal relationship between the latent variables and the explained value of variance (Hair and et al., 2010).Structural equation model encompasses two models: measurement model and the structural model; and the variables of the model are divided into two groups: latent variables and observed variables.In this research, organizational structure and entrepreneurial orientation are the latent variables, and formalization, complexity and centralization are observed variables that are considered as the indexes of the organizational structure.On the other hand, innovation, risk-taking, autonomy, pioneering and aggressive approach are observed variables that are considered as the criteria for measuring the entrepreneurial orientation.

Statistical population, sampling method, and sample size
e population of the research contains all employees in the companies of metal industry in the Iranian Kaveh Industrial City, which includes 4700 employees.e companies of the metal industry in the Iranian Kaveh Industrial City (36 companies) were divided into 4 groups: aluminum metal manufacturing companies, non-aluminum metal companies, household appliances, and automobile.
Relying on the relative stratifi ed random sampling method, 12 companies out of the 36 active companies in the metal industry were selected as the sample.en using the Cochran formula, we specifi ed the sample size for our 4500 subject population.To use the Cochran formula it is necessary to consider its assumptions.e assumptions of the Cochran formula include: p=q=50% (on the basis of probabilistic method); z is the standard statistic for normal distribution that is equal to 1.96 at the confi dence level of 95%; d is the maximum allowable error (equal to 5% for this research); and N is the number of the employees in all relevant companies.e sample size (n) is calculated according to equation 1 on the basis of the Cochran formula (Saraei, 2000): (1) us using the equation 1, considering the number of the statistical population (4700), 355 subjects were selected as the statistical sample.At the last step, regarding the number of the employees of each company and the total sample, we calculated the sample of each company separately.It is to be mentioned that 370 questionnaires were distributed among which the number of 360 questionnaire were completed and got back (response rate of 97%), and 5 questionnaires were removed due to their incompleteness.us the statistical operation was conducted on 355 subjects.In order to collect the needed data of the research, we used Robbins's standard questionnaire (1998) for measuring the organizational structure, and we have used Dess and Lumpkin's standard questionnaire of entrepreneurial orientation (2005: 153) for measuring the entrepreneurial orientation.e formal validity of the questionnaire was tested through collecting the opinions of the experts (some professors of the University of Tehran) and the needed corrections ware applied on the questionnaire.On the other hand, to evaluate the reliability of the questionnaire we used Cronbach's alpha method, and the Cronbach's alpha coeffi cient for each of the dimensions was obtained as follow: complexity: 0.79; formalization: 0.82; centralization: 0.77; innovation: 0.80; risk-taking: 0.72; autonomy: 0.76; pioneering: 0.77; and aggressive approach: 0.81.Since all coeffi cients are higher than 0.7, thus the measurement instrument of the research is reliable (Nunnally, 1978).After collect-ing the questionnaires, we fi rst conducted exploratory factor loading using SPSS 20.Since all extracted values in the communalities table were higher than 0.5, thus no one of the factors was removed from the analysis.At the next step, we conducted confi rmatory factor analysis using LISREL 8.8 in order to assess the used measuring model.e fi tness conditions of the model are as follow: the signifi cant level obtaining from the chi-square test (p-value) is higher than 0.05; the ratio of chi-square to degree of freedom is less than 3; the value of the statistic of Root Mean Square Error of Approximation (RMSA) is less than 0.05; the value of comparative fi tness index (CFI), general fi tness index (GFI), adjusted general fi tness index (AGFI), and non-norm fi tness index (NNFI) are higher than 0.9 (Joreskog and Sorbom, 1996).As shown in fi gure 2, p-value is equal to 0.073, RMSA statistic is equal to 0.065, and the ratio of chi-square to degree of freedom less than 3.

Data collection instrument; reliability and validity
Moreover, other outputs of LISREL showed that the value of CFI is equal to 0.943, the evaluated value of Z is higher than 1.96; and the values of GFI and AGFI are equal to 0.927 and 0.911 respectively.us the measurement models of the two main constructs of the research have an acceptable fi tness.

Data analysis
Since the correlation coeffi cient is the base for determining the precision of the regression estimation, thus these two techniques have to be used together.In order to test the hypotheses we fi rst used the Spearman's Correlation test (to determine the direction and intensity of the relationship between the variables) and multi-regression (to predict the changes in dependant variable by the independent variables) using SPSS 20; then the causal relationship between the dependant variable and the independent variables as tested in LISREL 8.8 in the form of structural equation model.Tables 1 and 2 show the results of correlation and regression tests respectively.Since in the regression and correlation matrixes the level of signifi cance is less than the error value (0.05), thus we can claim at 95% confi dence level that the relationship between organizational structure (and its dimensions) and the entrepreneurial orientation is signifi cant.Moreover, the negative sign of the coeffi cients show implies the inverse relationship between the two constructs, and the beta coeffi cients show that 56% of the changes in entrepreneurial orientations is predicted by complexity, 34% of it is predicted by formalization, and 14% is predicted by the centralization.
At the next step, we assessed the causal relationship between the organizational structure (and its dimensions) and the entrepreneurial orientation in structural model.As shown in fi gure 3, all mentioned suitability conditions of the fi tness model are true here.Moreover, the relationship between the organizational structure and the entrepreneurial orientation is signifi cant and inverse; i.e. the organizational structure has a negative effect on the entrepreneurial orientation.is point will be illustrated in the conclusion section in more details.

DISCUSSION AND CONCLUSION
As pointed out in the theoretical foundations of the research, the experts of diff erent fi elds believe that the entrepreneurial activities of the employees in organization have a considerable eff ect on the successfulness of that organization.Many researches show that diff erent factors play role in the appearance of the entrepreneurial orientations of employees, among which one can refer to the resources of the organization, management of the organization, organizational structure, and organizational culture (e.g.Yao, et al, 2009;Learner and Shaker, 2007;Caruana, et al, 2002).In the main hypothesis of the research we found that the structure of the organization aff ects the entrepreneurial orientation of the employees.In this regard, the results of Jogartnam, et al (2006) showed that organic structure of the organizations can lead to the increase of innovative activities of the employees considerably.Moreover, Zahra and Covin (1995) stated that the organizational structure is one of the factors that play a decisive role in the organizational entrepreneurship.
us our fi ndings are consistent with the fi ndings of the mentioned researches.Besides, on the subject of the complexity, Learner and Shaker (2007) have stated that the lack of complexity of the organizational structure and the consistency of the structure with the organizational criteria will lead to the improvement of the organizational entrepreneurship.Strict and rigorous rules and regulations in the organization is a factor that decreases the entrepreneurial orientation of the employees in organization.Evangelia, et al, (2011) have concluded that the formalization is a factor that has a negative eff ect on the job independence and job diversity.Since the autonomy is one of the dimensions of entrepreneurial orientation, the mentioned research confi rms the eff ect of the formalization on the entrepreneurial orientation of the employees of organization.In yet another research, Caruana, et al, (2002) found that in the organizations with decentralized systems, higher levels of creative ideas will be produced.And fi nally, Lumpkin, et al, (2010) have stated that the autonomy has a direct relationship with the centralization and it is the most important and most eff ective dimension of the entrepreneurial orientation that leads to the improvement of the organizational performance.e fi ndings of our research confi rm they results.

SUGGESTIONS
Considering the confi rmation of the main hypothesis of the research, we suggest that the managers of metal industries reduce the scale of the formalization and complexity of the organizational structure on one hand, and make the employees participate in the decisions of the organization on the other hand to make them ready to nurture their entrepreneurial orientation.Additionally, for the next researches we suggest the researchers to focus on the other factors like the organizational culture, management styles, and other factors that aff ect the entrepreneurial orientation.Moreover, the researchers can study the barriers that make trouble for the establishment of new businesses from both individual and organizational points of view and study each of these organizational factors on the diff erent types of individual factors one of which is the entrepreneurial orientation of the people.Next studies can investigate the factors that play a mediating role in the relationship between the organizational structure and the entrepreneurial orientation, as Lumpkin and Dess (1996) had suggested to study the mediating variables in the relationship between the entrepreneurial orientation and the organizational performance (including the environmental variables and the organizational variables).
