While China’s outward foreign direct investment (OFDI) is growing rapidly, few studies have considered the impact of this growth on product quality. This study uses microdata at the enterprise level to investigate the effects of OFDI on product quality and export trade, from the perspective of enterprise heterogeneity. The results denote that (1) OFDI improves product quality, which is caused by the direct promotional effect of OFDI and the productivity effect brought by OFDI. (2) As OFDI of low productivity enterprises creates a productivity effect and leads to a promotional effect on product quality enhancement, the magnitude is significantly higher than that of high productivity enterprises. (3) Product quality enhancement significantly increases the promotional effect on exports induced by OFDI of low productivity enterprises, while simultaneously significantly suppressing the promotional effect on exports induced by OFDI of high productivity enterprises. (4) The promotional effect of OFDI on exports decreases as productivity increases, and OFDI significantly promotes exports of low productivity enterprises and has no significant effect on high productivity enterprises. These results suggest that China should continue to expand the space for international cooperation and encourage enterprises to invest overseas, especially those facing export pressures.

The outflow of the rural labor force has a great impact on the location distribution of agricultural production, which has not attracted enough attention in existing studies. This article describes the mechanism of agricultural production location adjustment and further studies the influence of a regional difference in labor endowment on agricultural production location adjustment. Based on commodity and province-level panel data calculation, the results show that the agricultural production location in China has been adjusted from the East to the Central and then to the West with accelerating transfer speed. Furthermore, it is found that the regional differences in labor endowment are the main driving force for the shift of low alternative crop production. The more labor-intensive the crop varieties are, the more obvious the influence of the regional differences in labor endowment is on the crop production location adjustment. Moreover, regional differences in labor endowment have little effect on the location adjustment of vegetable production, as expanding the vegetable market demand may offset the effect of labor supply shortage on the adjustment of vegetable production location. Therefore, it is necessary to formulate a regional industrial development plan consistent with the trend of agricultural production location adjustment, as well as promote the construction of agricultural circulation facilities and socialized services in less developed areas.
