The previous MCC's have the demerits of high cost and much manhour for rework because they are impossible for the standardization of products and have many manual connections. The customers require the products which can operate in connection with SCADA system by digitalizing the functions of the current MCC's and are systematized with capability of remote control. To solve these disadvantages and requirements, we developed the Electronic Motor Control System according to starting type for applying to fields based on this. This system has the various functions such as protection, measurement, and communication. Using these functions, it can monitor motor status through communication with the upper system and define the circuit for lower connection cost according to starting type and shorter manufacture period by program. The development of this product results in establishment of competitive structure with domestic competition and perfect automatic monitoring through linkage with SCADA system. In addition, it provides the comparable dominancy of receiving on orders in switch gear and adaptability to change of MCC market in Japan and Europe.

China has recently (28 August 2004) adopted a new act legalizing the electronic signature. This new act provides electronic signatures with the same legal status as handwritten signatures, and states that on-line certification providers will have to be created in order to ensure the security of on-line operations made using said signatures. This new act is intended to increase Chinese electronic business, and thus to raise the revenue China can expect from said business. And the law grants electronic signatures the same legal effect as handwritten signatures and seals in business transactions, and sets up the market access system for online certification providers to ensure the security of e-commerce. As Internet trade requires a reliable third party to identify the signers, the credibility of online certifying organizations is significant for the transaction security. So, considering the weakness of China's social credibility system, the law regulates that the online signatures certification providers should be approved and administered by governments.

This study aims at evaluating the impact of network formation variables and found to have positive impact on the economic performance and growth of the enterprises. The calucation of the weighted scores of networking statements brought some affirmative results to influence the performance of the enterprises. Through multiple regression and logistic regression models it is identified that network formation variables like service receiving status, consultation of the family, other business dummy and attendance in fair have some significant positive impact both on the growth and performance of the enterprises. In addition to above variables, from the set of enterprise characteristics natural logarithm of the market value of total assets and from the entrepreneurs' characteristics set of variables, schooling year and squared value of the experience have been found to have significant positive impact. Finally, it is concluded in the study that to enhance the performance and growth of the enterprises, government and policy rlated organizations need to consider important variables that have positive impact in supplying the entrepreneurial resources especially, developing the net-working relationship.
