Content: Although it had a a lower income level than India in 1980, China's 2006 per capita gross domestic product stands more than twice that of India's. This paper investigates the role of the business environment in explaining China's productivity advantage using recent firm-level survey data. The analysis finds that China has better infrastructure, more skilled workers, and more labor-hiring flexibility than India, but a worse access to finance and higher regulatory burden. Infrastructure appears to be a key constraint for India: it lags significantly behind China, yet it has important indirect effects for the effectiveness of labor flexibility. Labor flexibility is also likely a major constraint for India, as evident in the predominance of small firms, the importance of firm size in accounting for India's disadvantage in productivity, and the complementarity of proxies of labor flexibility with infrastructure and access to finance. Interestingly, regulatory uncertainty has adverse effects in India but not in China. The empirical analysis suggests that it is important to consider country-specific growth bottlenecks and the indirect effects of policy reforms

Content: This paper uses a new data set of 12,000 firms in China to estimate the returns to research and development investment and its spillover effects, and investigates how the returns to research and development depend on firm incentives. For the firms in the sample, the results show that on average firm output increases around 0.4 yuan for each additional 1 yuan spent on research and development in the previous year, and there is high research and development return regardless of whether the analysis deals with the endogeneity of research and development intensity. Interestingly, the marginal return to research and development is significantly higher in firms whose chief executive officers were not appointed by the government and lower when the chief executive officer's pay is directly related to annual performance. The return to research and development is higher in relatively poor regions and for firms with worse access to finance. There are also non-trivial research and development spillover effects

Content: This paper examines the role of firms' government connections, defined by government intervention in the appointments of Chief Executive Officers and the status of state ownership, in determining the severity of financial constraints faced by Chinese firms. In line with the previous literature, the paper demonstrates that investment by non-state firms is highly sensitive to internal cash flows, while no such sensitivity is found for government-owned enterprises. Even within the subset of non-state firms, government connections are associated with substantially less severe financial constraints (less reliance on internal cash flows to fund investment). The paper also finds that large non-state firms with weak government connections are especially financially constrained, due perhaps to the formidable hold that their state rivals have on financial resources after the "grabbing-the-big-and-letting-go-the-small" privatization program in China. Firms with government-appointed Chief Executive Officers also have significantly lower investment intensities, due perhaps to their lower-powered incentives. The empirical results suggest that government connections play an important role in explaining Chinese firms' investment behavior and financing conditions, and provide further evidence on the nature of the misallocation of credit by China's dominant state-owned banks
