Based on data of China's 31 provinces for the year 2003-2014 with panel threshold regression method, we studied the relevance of R&D investment and technological innovation from the perspective of financing environmental. The results show that, R&D funding and technological innovation are significantly positive correlated, and the financial structure and financial support are also significantly positive correlated with the scientific and technological innovation, and the realization of technological innovation and foreign investment intensity are significantly negative correlated. The R&D investment and technological innovation have a higher correlation with higher market-driven degree and financial support degree. While the correlation between R&D investment and technological innovation is lower with foreign investment degree.

The random complex variable is a kind of random variable which in complex number as the random variable. In this paper, study on mathematical conjecture of random complex variable, two-dimensional joint distribution and complex expected, complex variance and other common statistics in the real and imaginary part of the random variables satisfy the independent standard normal distribution condition.

It will certainly obey a probability distribution for any continuous random financial data. If in any period of observation, the observed value of a set of random financial data is finite list, its actual distribution not equal empirical distribution and actual distribution is known but parameters, it is available to estimate the parameters of actual distribution through value of a finite point set. From empirical distribution to actual distribution, this kind of mathematical behavior constitutes the mapping of distributions. Mapping of distributions are able to estimate parameters of actual distribution, thus determine the actual distribution of data, lay the foundation for the subsequent data statistics.
