Intangible assets ecommerce technologyWhat are the four big factors of intangible assets? Some economists indicated they include knowledgeable capital, human capital, social capital and entrepreneurs capital. Nowadays, globalization and increased competition will cause new types of pressure to influence US economic growth. So, US companies need have flexibility, the ability to immediately adapt to market developments, and pro-activism in creating future markets. The relative importance of physical growth: However, soft production factors, that is those related to personal knowledge are becoming more important to influence US future economic growth, which regards to human capital and knowledge as driving factor of economic growth in industries developed countries, such as US.All these soft production factors can be grouped in what is known intangible assets. These assets can be defined as non-material factors that contribute to enterprise performance in the production of products or the provision of services, or that are expected to generate future economic benefits to the entities or individuals that control their deployment ( Akerlof & Kranton, 2000).Whether it has a close relationship between these intangible assets and US regional economic growth? Some economists had researched to have more reliable quantitative statistical information to do report in above four big factors how to effect on US regional economical growth influence. Their report indicated that returns from human and social capital are taken as homogeneous for US all regions. They also indicated these two sets of questions in their report. The first one, dealing with knowledge accumulation, addresses, among others the following issues: (a) How does innovation and knowledge accumulation occur within firms and hoe does it impact on economic performance?(b) What is the role of universities in regional, national and global knowledge accumulation processes?The second set of questions addresses the key knowledge diffuses over space and how this diffusion impacts on economic performances.In particular: (c) To what extent knowledge diffusion is conditioned by spatial proximity?(d) What is the impact of knowledge accumulation and diffusion on economic performance?They indicated to answer these questions, having reliable measures of how innovation process occurs, of the actors that take part in it and the mechanisms that are in place is important. They pointed out that the systemic nature of US regional intangible asset demands indicators that grasp two kinds of capabilities: network capabilities, i.e. connectivity, both intra-and-inter-regional and organizational capabilities, as well as their dynamic in US. These indicators have been applied to the study of linkages and relationships between US firms and between US firms and US universities, highlighting the mechanisms through which those actors contribute to the processes of knowledge accumulation, generation and diffusion. They also found results: How does knowledge accumulation occur within US firms and how does it impact on US economic performance? They included collaborations with competitors are most commonly undertaken at early stages of the development projects, those with buyers and suppliers are more likely to result in the introduction of new products and processes: At the same, it has been highlighted that, regardless of the industry, the most innovative firms, i.e. those more able to absorb knowledge are more likely to participate in collaborative networks.
