This paper, based on pieces of observed data of China ‘s 30 provinces during 2007 to 2019, applies fixed effect model to study the impacts of green financing on dual green innovation, and applies institutional economics theory to discuss the Moderation of institutional environment. Green financing can largely increase the local tentative green innovation, and also increase the open green innovation level in a less manner. Green financing is impacted by local institutional environment during transforming to dual green innovation, the higher marketing degree, intelligence protection extent and governance extent, the higher transforming. Institutional environment promotes the transforming to tentative green innovation of green financing in a stronger manner than to open green innovation.

Rural industrial integration is a fundamental approach to agricultural industrial bloom, and also a key solution to rural, agricultural and farmers’ issues. Increasing rural industrial integration level is a critical means to agricultural economy. This paper uses entropy weights to estimate 31 Chinese provinces’ 2008 to 2020 rural industrial integration level, and analyzes the spatial convergence and differentiated characteristic based on spatial conditionalβconvergence model. Results show that rural industrial integration level is low, only 40% of the target. Regionally, horizontal rising rate displays a deceasing tend from east, west and to central. Provincewide variance is less than cross-provincial. China’s rural industrial integration level is outstandingly of spatially conditionalβconvergence, with its convergence period shortened by 6 years. Rural industrial integration level is mostly contributed by financing agriculture, agricultural technical advances and farmers’ rising consumption level, but its convergence is slightly constrained by human capital. Spatially, rural industrial integration level in three areas is of notable “club convergence”, higher that the national average, also with a stronger spatial positive overflowing effect. Temporally, convergence rate in 2016 to 2020 is higher than 2008 to 2015, in which economic development and human capital work variably in direction and extent. This paper presents suggestions on optimizing top design, and modernizing agricultural industries, boosting financing agriculture, agricultural technical advances and farmers’ consumption level, improving imbalanced agricultural industrial integration, paying attention on talents, fulfilling the positive promotion of human capital on rural industrial integration level and high value convergence, and establishing a concept of wholly national rural industrial integration system and realizing a balanced development of nationwide rural industrial integration.

Urban mining refer to the recyclable secondary resource, its stock is significant to mitigate resource pressure and promote circular economy. This paper uses an up-to-down way to calculate the in-use stock of copper, iron and aluminum in Fujian province during 1978 to 2016. The stocks of copper, iron and aluminum had increased by 10, 15 and 22 times, respectively, equivalent to 2.4, 290, and 7.4 million tons. In 2016, average stock per person of copper, iron and aluminum is 58kg, 7.6t and 191kg, far below the developed nations. Their sources indicate that infrastructure contribute to copper stock at most, up to 62%, most from electronic lines, construction contribute to iron and aluminum up to 80% and 40%, most from residence constructions. This research also sets up a long term stock database of copper, iron and aluminum for Fujian province, which is used to analyze their stock size, increment mode, category and department. This paper provides data support for Fujian to develop and use urban mining, and offers references for provincial or city management of copper, iron and aluminum resources.

Mineral reserve place can help maintain China’s global position in preponderant minerals, increase speaking power, guarantee supply of bulkmineral resources, and promote the global allocation and sustainable use of mineral resources. This paper, based on the geology of Tibetan Plateau, discusses the necessity of Tibetan Plateau as mineral reserve place from national economic security, ecology, balancing resources allocation, increasing global market speaking power, defusing over production capacity, views fromminerals, location,exploration extent and works, and presents suggestions in setting up mineral reserve places exclusive fund, establishing management system and planning. 
