Coagglomeration of formal and informal industry: evidence from India
分析了印度正规与非正规制造业企业的共同集聚模式，发现买卖双方和技术联系是主要驱动因素，且这种集聚主要促进中小型正规企业的进入。
A large and growing informal sector is a major feature of developing countries. I analyze coagglomeration patterns between formal and informal manufacturing enterprises in India, and study (i) the causes underlying these patterns, and (ii) the positive externalities, if any, on the entry of new firms. I find that buyer–seller and technology linkages explain much of formal–informal coagglomeration. I also find that this sectoral, within-industry, coagglomeration matters mostly to small- and medium-sized formal firms births. Traditional measures of agglomeration remain important in explaining new industrial activity, whether in the formal or the informal sectors.
