Location determinants of high-growth firms

County-level location patterns of INC5000 companies provide one map of American entrepreneurship and innovativeness, and understanding the local factors associated with these firms’ emergence is important for stimulating regional economic growth and innovation. We draw on the knowledge spillover theory of entrepreneurship to motivate our regression model, and augment this theory with additional regional features that have been found to be important in the firm location literature. Zero-inflated negative binomial regressions indicate that these firms exist in counties with larger average establishment size, higher educational attainment and more natural amenities. Income growth, a mix of higher paying industries, and more banks per capita are associated with a smaller presence of these types of firms, all else equal. We conclude that the local conditions favouring high-growth firms are likely to be different from those favouring new firms in general, and that these conditions differ significantly in urban and rural areas and by industrial sectors.     

From Experience: Demystify Creativity, Enhance Innovation

Creativity need not be a chance occurrence. The authors of this article believe there is a technology that facilitates creativity. It is a technology that can be learned and applied and managed. They describe the specific steps that they followed in helping a group of R&D professionals learn, apply, and manage the creative processes in the lab. It is a story of practical steps that dealt with the everyday realities of managing in a large corporation.     

Perspectives for a theory of marketing

Perspectives for a theory of marketing are outlined. Both the so-called marketing and broadened marketing concepts are inadequate conceptualizations of the marketing process. A theory of marketing should be formulated at the macro rather than the micro level and emphasize the positive rather than the normative problem-solving dimensions of the subject matter.     

从5000户企业存货指数看我国经济周期波动

国内外理论和实证研究表明,存货变动具有顺经济周期特征,可以用来监测经济运行。为此,我们基于人民银行5000户企业问卷调查数据,尝试编制了5000户企业产成品存货指数。分析显示,5000户企业存货指数波动基本呈顺经济波动周期特点,与经济波动能够较好地拟合,但存在约1个季度的滞后。从目前情况看,5000户企业产成品存货指数在连续5个季度上升后首次下降,显示企业生产经营扩张态势暂时趋缓。
